2020-02-13Adding a link to the *crt*.o files in the local install directoryMohammad Akhlaghi-1/+16
Until now, we defined `LIBRARY_PATH' to fix the problem of the `ld' linker of Binutils needing several `*crt*.o' files to run. However, some software (for example ImageMagick) over-write `LIBRARY_PATH', therefore there is no other way than to put a link to these necessary files in our local build directory. With this commit, we fixed the problem by putting a link to the system's relevant files in the local library directory. This fixed the problem with ImageMagick. Later, when we build the GNU C Library in the project, we should remove this step. This bug reported by Raul Castellanos Sanchez.
2020-02-11Using backup server when original download server failsMohammad Akhlaghi-4/+12
Until now, the main download script could only check one server for the given URL. However, ultimately the actual server that a file is downloaded from is irrelevant for this project: we actually check its checksum. Especially in the case of software (which are distributed over many servers), this can usually be very annoying: the servers may not properly communicate with the running system and even the 10 trials won't be enough. With this commit, the download script `reproduce/analysis/bash/download-multi-try' can take a new optional argument (a 5th argument). It assumes this argument is a space-separated list of server(s) to use as backup for the original URL. When downloading from the original URL fails, it will look into this list and try downloading the same file from each given server.
2020-02-01IMPORTANT: reproduce/software/bash renamed to reproduce/software/shellMohammad Akhlaghi-3/+3
Until now the shell scripts in the software building phase were in the `reproduce/software/bash' directory. But given our recent change to a POSIX-only start, the `configure.sh' shell script (which is the main component of this directory) is no longer written with Bash. With this commit, to fix that problem, that directory's name has been changed to `reproduce/software/shell'.
2020-01-27Initial scripts compatible with Dash (minimalistic POSIX)Mohammad Akhlaghi-1/+1
Until now, the initial project scripts were primarily tested with GNU Bash. But Bash is not generally available on all systems (it has many features beyond POSIX). Because of this, effectively we were imposing the requirement on the user that they must have Bash installed. We recently started this with setting the shebang of `project' and `reproduce/software/bash/configure.sh' to `/bin/sh'. After doing so, Raul and Gaspar reported an error on their systems. To fix the problem, I installed Dash (a minimalist POSIX-compliant shell) on my computer and temporarily set the shebangs to `/bin/dash', ran the project configuration step and fixed all issues that came up. With this commit, it can go all the way to building GCC on my system's Dash. After this stage (when `high-level.mk' is called), there is no problem, because we have our own version of GNU Bash and that installed version is used. Probably some more issues still remain and will hopefully be found in the future. While doing this, I also noticed the following two minor issues: - The `./project configure' option `--input-dir' was not recognized because it was mistakenly checking `--inputdir'. It has been corrected. - The test C programs now use the `<<EOF' method instead of `echo'. - In `basic.mk', the extra space between `syspath' and `:=' was removed (it was an ancient relic!).
2020-01-22Perl is now a dependency of Coreutils, LD_LIBRARY_PATH in basic.mkMohammad Akhlaghi-66/+79
Until now Perl was built after Coreutils, but I recently noticed that Coreutils actually uses Perl while creating its manpages. So it is now built before Coreutils. Also, while testing on an Amazon AWS EC2 server, we noticed that Coreutils can't build its man page for `md5sum'. The problem was found to be due to the fact that until now, we weren't actually setting LD_LIBRARY_PATH to our installed library path in `basic.mk'. Therefore, it would crash because the server had an older version of OpenSSL than the one that the template's Coreutils was built with. In the meantime (while addressing the issues above, because we only had one thread on the AWS server) I also noticed a few programs that were using a summarize compilation command (that just prints `CC xxx.c' instead of the whole command) so I fixed them by adding `V=1'. This bug was found by Idafen Santana Pérez.
2020-01-20IMPORTANT!!! Configuration Makefiles now have a .conf suffixMohammad Akhlaghi-3/+3
Until now, the configuration Makefiles (in `reproduce/software/config/installation' and `reproduce/analysis/config') had a `.mk' suffix, similar to the workhorse Makefiles. Although they are indeed Makefiles, but given their nature (to only keep configuration parameters), it is confusing (especially to early users) for them to also have a `.mk' (similar to the analysis or software building Makefiles). To address this issue, with this commit, all the configuration Makefiles (in those directories) are now given a `.conf' suffix. This is also assumed for all the files that are loaded. The configuration (software building) and running of the template have been checked with this change from scratch, but please report any error that may not have been noticed. THIS IS AN IMPORTANT CHANGE AND WILL CAUSE CRASHES OR UNEXPECTED BEHAVIORS FOR PROJECTS THAT HAVE BRANCHED FROM THIS TEMPLATE. PLEASE CORRECT THE SUFFIX OF ALL YOUR PROJECT'S CONFIGURATION MAKEFILES (IN THE DIRECTORIES ABOVE), OTHERWISE THEY AREN'T AUTOMATICALLY LOADED ANYMORE.
2020-01-19GNU Make updated to version 4.3Mohammad Akhlaghi-1/+1
GNU Make 4.3 was just announced, so I have updated it here is well. This was important because until now the installable version was in alpha-mode (4.2.90), now its a stable version.
2020-01-19LIBRARY_PATH is set accordingly based on the hostMohammad Akhlaghi-4/+11
Until now, GCC wouldn't build properly on Debian-based operating systems because `ld' needed to link with several necessary C library features like `crti.o' and `crtn.o' (this is an `ld' issue, not GCC). The solution is to add the directory containing them to `LIBRARY_PATH'. In the previous commit, I actually searched for these files, but while testing on another system, I noticed that it can be problematic (other architectures may exist). With this commit, we are actually finding the build architecture of the running GCC (which is the same as the `ld') and using that to fix a fixed directory to `LIBRARY_PATH'.
2020-01-01Copyright statements updated to include 2020Mohammad Akhlaghi-2/+2
Now that its 2020, its necessary to include this year in the copyright statements.
2019-12-04Perl built without -shared on macOSMohammad Akhlaghi-1/+11
Until now, while building Perl, the `-Dlddlflags="-shared $$LDFLAGS"' option was being used for all systems. However, this caused `symbol(s) not found for architecture x86_64' problems on macOS systems. With this commit, this configure option is only passed for GNU/Linux systems. With it, Perl can be built nicely on both GNU/Linux and macOS.
2019-11-08Matplotlib problem on macOS system with GNU GCC fixedMohammad Akhlaghi-2/+2
Until now when building Matplotlib on macOS systems, we were using the default C compiler. However, while Yahya Sefidbakht (previously) and Mahdieh Nabavi (now) were trying to build the template, on their macOS using the GNU Compiler Collection (GCC), we found that Matplotlib needs special macOS headers that GCC doesn't recognize. With this commit, when Matplotlib is being built on macOS systems, it uses `clang' and this fixed the problem (so far checked on Mahdieh's machine).
2019-11-08Minor corrections applied in software buildsMohammad Akhlaghi-2/+7
While working on a different branch to build the GNU C Library, I noticed a few places in the template that need corrections which are now applied: 1. A new-line character after the "C compiler works" notice at the start of the configure script. 2. Removing possible `::' in the `LD_LIBRARY_PATH' definition of `basic.mk'. Note that its not necessary in the other steps because we don't use any outside-defined `LD_LIBRARY_PATH'. 3. Building GMP for C++ and also with `--enable-fat'. 4. Removing the unpacked Perl tarball directory after its installation.
2019-11-06Perl is now built as a basic dependency of the templateMohammad Akhlaghi-4/+50
Perl is necessary to build Texinfo and later to build LaTeX. Until now we were just using the host operating system's installation of Perl, but in some instances that Perl can be too old and not suppor the features necessary. With this commit, Perl is now built from source during the basic installation step of the template. This was reported by Idafen Santana Pérez, after trying the pipeline on an Amazon AWS EC2 system (a Linux distro by Amazon for its cloud services).
2019-10-30Tarballs set as order-only prerequisites, not needed for build callsMohammad Akhlaghi-134/+136
Until now, the tarballs were the first normal prerequisite of the software. As a result if their date changed, the whole software would be re-built. However, for tarballs specifically, we actually check their contents with a checksum, so their date is irrelevant (if its newer than the built program, but has the same checksum, there is no need to re-build the software). Also, calling the tarball name as an argument to the building process (for example `gbuild') was redundant. It is now automatically found from the list of order-only prerequisites within `gbuild' and `cbuild' (similar to how it was previously found in the `pybuild' for Python building). A `README.md' file has also been placed in `reproduce/software/make' to help describe the shared properties of the software building Makefiles. This will hopefully grow much larger in the future.
2019-10-28HEALPix, Autoconf and Automake now in libraryMohammad Akhlaghi-0/+1
The tarball of HEALPix includes multiple languages and doesn't include the ready-to-run GNU Build System by default, we actually have to build the `./configure' script for the C/C++ libraries. So it was necessary to also include GNU Autoconf and GNU Automake as prerequisites of HEALPix. However, the official GNU Autoconf tarball (dating from 2012) doesn't build on modern systems, so I just cloned it from its source and bootstrapped it and built its modern tarball which we are using here.
2019-09-26Working project when downloaded from arXivMohammad Akhlaghi-12/+19
Until now, we were assuming that the users would just clone the project in Git. But after submitting arXiv:1909.11230, and trying to build directly from the arXiv source, I noticed several problems that wouldn't allow users to build it automatically. So I tried the build step by step and was able to find a fix for the several issues that came up. The scripting parts of the fix were primarily related to the fact that the unpacked arXiv tarball isn't under version control, so some checks had to be put there. Also, we wanted to make it easy to remove the extra files, so an extra `--clean-texdit' option was added to `./project'. Finally, some manual corrections were necessary (prior to running `./project', which are now described in `README.md'. Most of the later steps can be automated and we should do it later, I just don't have enough time now.
2019-09-06Updated versions of several softwareMohammad Akhlaghi-36/+35
New versions of astropy, bash, cmake, curl, findutils, gawk, gcc, ghostscript, git, make, gsl had recently come so they are updated with this commit. About GNU Findutils and GNU Make: I was bootstrapping (building the tarball of) these two separately separately because their standard tarball release had problems on some systems. Both have been updated now so I am no longer using my own webpage as their main URL. A special note about GNU Make. I just noticed that during bootstrapping, GNU Make would use the fixed version string of `4.2.90' for any commit!!! But fortunately they have officially released their 4.2.90 version, so we are safely using their own webpage. The only difference is the compression format. My old bootstrapped build was `tar.lz', but the standard release is `tar.gz'. Also, all the basic programs (installed in `.local/bin') in `basic.mk' are now existance-only dependencies (after a `|'). Because later programs just use them at a very basic level, so there is no need to rebuild everything when Bash gets updated for example.
2019-08-08Static PatchELF only built when static C library existsMohammad Akhlaghi-7/+10
Until now, when building PatchELF, we would always require that it be done statically. However, some systems don't have a static C library available for linking. This cause a crash in the static building of PatchELF. But a static PatchELF is necessary for correcting RPATH in GCC's outputs. With this commit, in the configure script we check if a static C library is linkable for the compiler. If it isn't then `host_cc' will be set to 1 and GCC won't be built. We also pass the result of this test to `basic.mk' (through `good_static_lib'), so if a static C library isn't available, it builds a dynamically linked PatchELF. This bug was reported by Elham Saremi.
2019-08-05Backup repository set to http://akhlaghi.org/reproduce-softwareMohammad Akhlaghi-11/+13
Some of the software tarballs are directly available on their webpage (for example due to build problems on systems, where we had to clone the software and build its tarball ourselves until the next release). Until now, only for these software, these tarballs were hosted on `http://akhlaghi.org/src'. But now, I have moved a clone of the software backup repository (including all its software) to `http://akhlaghi.org/reproduce-software'. To be more clear and have a single place for the backup software, the URL of those software has also been updated in the project source.
2019-08-01Typo in previous commit correctedMohammad Akhlaghi-1/+0
After making the previous commit, I noticed an extra line (redundantly defining a wrong `BASH_ENV') that should have been deleted. It has been corrected.
2019-08-01Bash startup script for every recipeMohammad Akhlaghi-0/+5
Until now the only way to define the environment of the Make recipes was through the exported Make variables (mostly in `initialize.mk' for the analysis steps for example). However, there is only so much you can do with environment variables! In some situations you want slightly more complicated environment control, like setting an alias or running of scripts (things that are commonly done in the `~/.bashrc' file of users to configure their interactive, non-login shells). With this commit, a `reproduce/software/bash/bashrc.sh' has been defined for this job (which is currently empty!). Every major Make step of the project adds this file as the `BASH_ENV' environment variable, so the shell that is created to execute a recipe first executes this file, then the recipe. Each top-level Makefile also defines a `PROJECT_STATUS' environment variable that enables users to limit their envirnoment setup based on the condition it is being setup (in particular in the early phase of `basic.mk', where the user can't make any assumption about the programs and has to write a portable shell script).
2019-07-31GCC: libstdc++ has a link to libiconvMohammad Akhlaghi-0/+1
After adding the libiconv library to the template, the C++ library uses three of its functions (`libiconv', `libiconv_open' and `libiconv_close'). However, it doesn't explicity link with it inside its shared library! I tried by exporting `LIBS=-liconv' before the GCC configure script but it crashed as soon as it went on to the second GCC building stage (because this environment variable was no longer present there). I also tried adding the C++ configure option of `--enable-cstdio' to the GCC configure options (so it doesn't use iconv according to the manual), but it made no change. With this commit, as a brute-force solution, `patchelf --add-needed' is run on the installed `libstdc++.so', so `libiconv.so' is explicitly included inside the `libstdc++' shared library. This bug was found by Roberto Baena Galle while trying to load Matplotlib (which needed the C++ library). This fixes bug #56702.
2019-07-29Checking software tarball checksums before building softwareMohammad Akhlaghi-60/+76
Until now, there was no check on the integrity of the contents of the downloaded/copied software tarballs, we only relied on the tarball name. This could be bad for reproducibility and security, for example on one server the name of a tarball may be the same but with different content. With this commit, the SHA512 checksums of all the software are stored in the newly created `checksums.mk' (similar to how the versions are stored in the `versions.mk'). The resulting variable is then defined for each software and after downloading/copying the file we check to see if the new tarball has the same checksum as the stored value. If it doesn't the script will crash with an error, informing the user of the problem. The only limitation now is a bootstrapping problem: if the host system doesn't already an `sha512sum' executable, we will not do any checksum verification until we install our `sha512sum' (as part of GNU Coreutils). All the tarballs downloaded after GNU Coreutils are built will have their checksums validated. By default almost all GNU/Linux systems will have a usable `sha512sum' (its part of GNU Coreutils after all for a long time: from the Coreutils Changelog file atleast since 2013). This completes task #15347.
2019-07-28Single wrapper instead of old ./configure, Makefile and ./for-groupMohammad Akhlaghi-3/+7
Until now, to work on a project, it was necessary to `./configure' it and build the software. Then we had to run `.local/bin/make' to run the project and do the analysis every time. If the project was a shared project between many users on a large server, it was necessary to call the `./for-group' script. This way of managing the project had a major problem: since the user directly called the lower-level `./configure' or `.local/bin/make' it was not possible to provide high-level control (for example limiting the environment variables). This was especially noticed recently with a bug that was related to environment variables (bug #56682). With this commit, this problem is solved using a single script called `project' in the top directory. To configure and build the project, users can now run these commands: $ ./project configure $ ./project make To work on the project with other users in a group these commands can be used: $ ./project configure --group=GROUPNAME $ ./project make --group=GROUPNAME The old options to both configure and make the project are still valid. Run `./project --help' to see a list. For example: $ ./project configure -e --host-cc $ ./project make -j8 The old `configure' script has been moved to `reproduce/software/bash/configure.sh' and is called by the new `./project' script. The `./project' script now just manages the options, then passes control to the `configure.sh' script. For the "make" step, it also reads the options, then calls Make. So in the lower-level nothing has changed. Only the `./project' script is now the single/direct user interface of the project. On a parallel note: as part of bug #56682, we also found out that on some macOS systems, the `DYLD_LIBRARY_PATH' environment variable has to be set to blank. This is no problem because RPATH is automatically set in macOS and the executables and libraries contain the absolute address of the libraries they should link with. But having `DYLD_LIBRARY_PATH' can conflict with some low-level system libraries and cause very hard to debug linking errors (like that reported in the bug report). This fixes bug #56682.
2019-07-27DYLD_LIBRARY_PATH also fixed for macOS systemsMohammad Akhlaghi-6/+7
Until now we were only setting the `LD_LIBRARY_PATH' environment variable for GNU/Linux systems. But macOS systems use the `DYLD_LIBRARY_PATH'. With this commit, for better control over the environment, we are also fixing `DYLD_LIBRARY_PATH' in all the places that we are setting the general environment variables.
2019-07-26PatchELF built statically and updatedMohammad Akhlaghi-1/+7
Until now, like all other software, PatchELF would install with dynamic linking. However, PatchELF links with `libstdc++' so on one system, I noticed that PatchELF gives a segmentation fault and corrupts `libstdc++' while correcting its RPATH (after installing GCC). The solution is to build PatchELF statically. With this commit, we force PatchELF to be built statically (it only installs on GNU/Linux systems anyway, so there is no problem with static linking on macOS). This solved the problem on that system. While looking at its documentation, I also noticed that a new version of PatchELF has been released after almost three years, so it has been updated in the template also. This fixes bug #56673.
2019-07-08Rpath in libstdc++ and passing host_cc to high-levelMohammad Akhlaghi-1/+1
Until this commit, the addion of `-liconv' to `CXXFLAGS' in `high-level.mk' dependend on `host_cc', but I had forgot that `host_cc' isn't defined for `high-level.mk'. It is now defined for this Makefile also in the configure script. Also, the Standard C++ library depends on `libgcc_s.so.1', so after building GCC, it was necessary to add Rpath to it.
2019-07-07Texinfo installed as a dependency of M4Mohammad Akhlaghi-7/+18
While testing on a system with no Texinfo, we noticed that M4 depends on Texinfo. To fix this problem, with this commit, it is now included in the pipeline. While doing a clean build, a few minor issues were also found and corrected in the other rules.
2019-07-04Configuring wget without libiconvMohammad Akhlaghi-0/+4
On some Fedora systems, Wget's build conflicts with libiconv. With this commit, we use Wget's `--without-libiconv-prefix' configure option so it will be built without an outside libiconv.
2019-06-30Removing libiconv before building pkg-configMohammad Akhlaghi-0/+8
An existing `libiconv' can cause a conflict with `pkg-config', this is why `libiconv' depends on `pkg-config'. On a clean build, `pkg-config' is built first. But when we don't have a clean build (and `libiconv' exists) there will be a problem. With this commit, before re-building `pkg-config', we'll remove any possibly existing installation of `libiconv'.
2019-06-29Imported recent correction from Pierre Gajda, no conflictsMohammad Akhlaghi-1/+1
There was only a conflict with `.file-metadata'.
2019-06-29Added citation for TIDES, sorted progs alphabeticallyMohammad Akhlaghi-1/+3
While reviewing Prasenjit's commits, I noticed that we had forgot to add the citation for TIDES, also to make things clear, the program/library build rules are now sorted alphabetically. Finally, I noticed that after building the TiKZ PDF figures, it is crashing (like on Prasenjit's computer). After looking around, I noticed its because we were setting the of the `TEXINPUTS' environment variable to be the installed TeX Live directory (which was ultimately redundant because by default TeX will look into where it was installed). The important thing is just that we remove any possible value the host system has, not to set new directories.
2019-06-28Fixed a conflict with libiconv and pkg-configPierre Gajda-1/+1
Libiconv has to be installed before pkg-config otherwise there would be a compilation error: gconvert.c:61:2: error: #error GNU libiconv not in use but included iconv.h is from libiconv 61 | #error GNU libiconv not in use but included iconv.h is from libiconv
2019-06-28Corrections to basic buildPrasenjit Saha-1/+2
Several corrections were necessary in the basic build: 1) the version of GCC on some systems includes an `_' which would cause a crash when building the PDF. 2) libcharset had to be manually added to the Git build.
2019-06-28Libiconv built as a dependency of GitMohammad Akhlaghi-15/+22
Prasenjit Saha reported that while building on a macOS, Git complained about not finding `libiconv' functions. Therefore with this commit, `libiconv' is also built as a dependency of Git. Also, since the build of Binutils (and the subsequent GCC) doesn't depend on the exact versions of the other basic software, they are set as existance-only prerequsites (ignoring their timestamps). This is done to avoid re-building when it is not needed.
2019-06-14Binutils is built alone, before GCCMohammad Akhlaghi-40/+55
Until now, on GNU/Linux systems, GNU Binutils was built in parallel with other programs. As a result, the moment that the Binutils executables (most importantly `ld') are being installed, if another program is using them, we can have a crash. For some reason, this crash doesn't happen on Fedora or Arch Linux, but on some Debian-based distors, it causes the following crash when we are building Git (which happened to be built while Binuntils is being installed): credential-cache--daemon.o: file not recognized: File format not recognized In a following run of `./configure' (when Binutils has been installed), Git will build and install successfully. To fix this problem, with this commit, all basic programs are now a prerequisite of Binutils and Binutils is the sole prerequisite of GCC (which is the final target of `basic.mk'). Also, the GCC configure options were re-ordered to be easier to read (the `--with-*' options under each other, the `--enable-*' options under each other and so on).
2019-06-13Metastore now has rpathMohammad Akhlaghi-10/+16
Until now we hadn't noticed that Metastore's build doesn't include an `rpath'. As a result I got a crash during a Git commit. With this commit, on GNU/Linux systems, we now add rpath to the installed Metastore executable. During the build, I also cleaned up the Metastore build recipe to be more clear and readable (in particular we only check the user name and group name when metastore is actually built).
2019-06-12Imported recent work on Imfit, minor conflicts fixedMohammad Akhlaghi-2/+6
The recent work by Raul to import Imfit is now merged into the master branch. Only a few minor conflicts came up due to the update with CFITSIO (that Raul also done in parallel on this branch).
2019-06-12Imfit and libcurl: manually adding rpath on GNU/Linux systemsRaul Infante-Sainz-1/+5
While trying to debug the installation of Imfit, we found out that libcurl doesn't have rpath and is thus linking with the host system's libraries. So rpath is now manually added to the build of libcurl. We also found out that Imfit executables don't have rpath, so it was added to them too.
2019-05-09Typo, space instead of TAB, corrected in recipe of MetastoreMohammad Akhlaghi-27/+27
In the previous commits where Metastore's recipe was updated, all the `TAB's in the recipe were saved as spaces just before the commit (due to a copying and pasting from the terminal, not the text editor). With this commit, I am correcting this.
2019-05-09Metastore Git hooks properly written after its installationMohammad Akhlaghi-35/+34
Until now, in the recipe to build Metastore, we would store the current directory in a `current_dir' Bash variable before running `gbuild' to build Metastore. However, in this Makefile, we aren't using `.ONESHELL'. As a result, each un-quoted new-line character creates a new shell and the `current_dir' variable that we used afterwards was empty! This happened because until recently, Metastore was being built in `high-level.mk' (where `.ONESHELL' is activated, because we are using GNU Make to call that Makefile). But in `basic.mk', we are using the host's Make, which may not be GNU Make, so we can't use any GNU-only features. Also, this error was hard to notice, because we weren't using `&&' before writing the final target of Metastore! With this commit, both this issues are addressed: all the lines in the recipe are now quoted in the end with a backslash, and the steps before making the target are separated by `&&', not `;' (which doesn't cause a crash if the command fails). This fixes bug #56295.
2019-05-09Removed extra Binutils from GCC's prerequisitesMohammad Akhlaghi-1/+0
Until this commit, Binutils was brough up as a GCC prerequisite two times: Once as a special (`host_cc') dependency (for when we want to build GCC), another time as a dependency in every build. The first one is now obsolete: on MacOS systems where we don't build Binutils, we define its symbolic links in the same recipe. With this commit, we remove the first one, so Binutils is always a dependency of GCC.
2019-05-05Upgraded to GCC 9.1Mohammad Akhlaghi-26/+27
GCC 9.1 was just released and includes many new optimization features that can benefit projects in this template also. Also, the build directory of GCC has been moved inside the unpacked directory (similar to all the other programs). As a result, while GCC is being built, the `.build/software/build-tmp' directory will only have one directory for GCC. Until now, there was one `gcc-build' directory and one unpacked tarball.
2019-04-30New rule to build Coreutils, it is now built alongMohammad Akhlaghi-84/+107
Recently, after the installation of Coreutils, we added a step to manually run PatchELF over all the contents of the `$(ibdir)'. However, after a fresh test, this method failed: because while PatchELF was updating `mv', another program that was using `mv' couldn't do so and crashed. To fix this problem, Coreutils is now installed in a dummy directory also and the exact files that need `rpath' are identified and PatchELF is run on them (to be clean). Also, higher-level `basic.mk' software (higher-level than Bash), were re-organized so they depend on Coreutils. With this, we are no sure that when Coreutils is being built, it is the only program that is being built and PatchELF won't interfere with any other program. Also, OpenSSL and CMake were set to be bulit in parallel to speed up their build.
2019-04-30Imported some recent/parallel work, conflicts fixedMohammad Akhlaghi-4/+6
Especially because of the new convention regarding backslashes, there were many conflicts that are now fixed. But none were substantial.
2019-04-30End-of-line Backslashs no longer right under each otherMohammad Akhlaghi-378/+380
When we need to quote the new-line character we end the line with a backslash (`\'). Until now, our convention has been to put all such backslashes under each other to help in visual inspection. But this causes a lot of confusion in version control: if only one line's length is larger, the whole block will be marked as changed and thus makes it hard to visually see the actual change. It also makes debuging the code (adding some temporary lines) hard. With this commit, I went through all the files and tried to fix all such cases so only a single white space character is between the last command character and the backslash. Where there was an empty line (ending with a backslash, to help in visually separating the code into blocks), I put the backslash right under the previous line's. This completes task #15259.
2019-04-30Better configure checks to see if GCC can be builtRaul Infante-Sainz-2/+2
Until now, to test if GCC can use `sys/cdefs.h', we were building a small test program using it. But after testing on an Ubuntu 14.04, we noticed that the GCC test during the configure script passes, but GCC still can't be built. After some investigation we noticed its available in other directories, but during the build of GCC, those directories aren't used, and it only assumes it to be under `/usr/include'. So with this commit, we are only checking this particular location for this header, not a test run of GCC. After fixing this, we noticed that GCC's build crashed again because it couldn't link with `libc.a' (or `libc.so'). So we also added a for this library and added a new warning to inform the user what they might be able to do. Finally, we noticed that in one of the last steps of building GCC, we weren't using `&&', but `;', so the GCC name file would be built, even when the GCC build failed.
2019-04-30Running PatchELF on all programs after CoreutilsMohammad Akhlaghi-8/+27
Even though the Coreutils configure script says that it adds `rpath' to its executables, its executables don't have it. As a result, it goes to use the host operating system libraries, causing failures when they don't match with the template. Unfortunately after some tests with the configure script, I couldn't find any way to include `rpath'! Even though `-rpath-link' is present in all linking commands during Coreutils' build, the installed files still don't have it! So I was forced to use PatchELF. However, one problem is that Coreutils installs many programs, not just one like Bash or AWK. As a brute-force solution, with this commit, we are running PatchELF on all the installed programs. It won't hurt those that already have it, but it will fix all those that don't. With this commit, I am also making the following non-related small changes: - In `build-rules.mk', the `&&' characters were placed at the start of the line for better readability. - Bash, Readline and NCURSES are now built in parallel on systems that support it (during `basic.mk').
2019-04-29Added M4 as prerequisite of GMPRaul Infante-Sainz-1/+2
Until this commit, `m4' was not a prerequisite of `gmp'. However, during a test in Ubuntu 14.04 using one single core in the configure step, it crashed complaining about not having `m4' installed. With this commit, we set `m4' as a prerequisite of `gmp'.
