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.

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.

We recently moved the system's `rm' program absolute address to a shell
variable that is found during the `./project' script. But I had forgot to
account for the difference between the Make and Bash variable naming
differences. I had also forgot to add a value to the HOME variable.
With this commit both are corrected: the system's `rm' path is now called
`sys_rm' and the HOME variable is set.

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.

Until now the description of the commit message guidelines wasn't clear
enough and could cause confusion, in particular because it didn't describe
why some basic formatting issues are mandatory.
With this commit, it is explained that the main reason we require
contributors for follow this format is "consistency" within the
project. Also generally it was edited to become more elaborate and explain
the points more clearly.
I also ran a spell check over the whole file and fixed a few typos.
This correction was suggested by Mohammad-reza Khellat.

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.

Some bugs have been fixed in the new version of WCSLIB, so it has been
updated in the template.
|
|
The previous implementation of using shared memory to build software was
edited to be more clear and less prone to errors.
|
|
More than two releases and bug fixes have been made to libgit2. So we are
now using a more recent version in the template.
|
|
Until now, the template would unpack the software and build them directly
in the build directory of each project. After installation, the whole
unpacked directory is deleted. However, building the software involves the
reading and writing of millions of files, so on the long run, it can be bad
for the non-volatile memory (HDDs or SSDs), it can also be slightly slow.
To fix this, if the system has a shared-memory directory (commonly named
`/dev/shm'), we can do the temporary building of the software there. The
great thing about this unique directory is that it is actually in the RAM,
not on the HDD/SSD. This can slightly improve the speed (not much
probably), but more importantly it will not do any long-term harm to the
host's HDDs/SSDs.
With this commit, when there is a shared memory directory mounted in
`/dev/shm', and it has enough space (currently set to 2GB), the
`./configure' script will make `.build/software/build-tmp' as a symbolic
link to a fixed directory there. Otherwise, it will just build it as a
directory in the project's shared directory.
The structure has been defined in such a way that we can later easily add
different standard shared-memory locations (for different operating
systems).
This completes task #15336.

Configure script: when `texlive-ready-tlmgr' is not created, it is similar
to not having installed TeXLive. A check was added so in this scenario the
`./configure' script doesn't crash.
high-level.mk: `cairo' and `pixman' are now installed in parallel and with
`V=1' (so the full compilation and linking command is printed).
|
|
In one of the last few commits, the commands in the recipe of libgit2 was
merged with `&&' so it stops if anything fails. But I had forgot to add a
`;' at the end of the `install_name_tool' command. This is corrected with
this commit.
|
|
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.
|
|
While doing a clean build, several issues were found in the pipeline and
corrected. The main issue was that with the recent installation of
`libiconv', the GCC standard C++ library depends on `libiconv', so we need
to explicity add an `-liconv' to any C++ compilation.
The other corrected points are:
- The C++ compiler is now explicitly defined in `CXX'.
- libgit2 and WCSLIB's recipes weren't using `&&' between statements, so
if there was an error, it would still build the target!
- The CMake bootstrapping script now builds much faster in parallel.
|
|
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.
|
|
To build the software, we need a C/C++ compiler. But until now at configure
time there was no check on this. As a result, when the system didn't have
them, the user would only learn in a crash of the programs.
With this commit, some checks have been added at configure time to do basic
checks and inform the user if necessary.
|
|
Until now there was no guideline in `README-hacking.md' to describe/suggest
a good format for commit messages.
With this commit a point has been added in the "Tips" section to help new
developers contribute more smoothly.
The necessity of this paragraph was pointed out by Mohammad-reza Khellat.

Until now, we were using the `--enable-single' configure-time option of
FFTW to build its single-precision library. The reason was that according
to the output of `./configure --help', this was equivalent to
`--enable-float'. However, the single precision library wasn't being built.
As a result, on systems that already had it, SExtractor would use the
system's library and on other systems, it would simply not pass the
configure step.
With this commit, we are now using `--enable-float' which fixes this
problem and installs the `libfftw3f*' libraries (showing that it is not
equal to `--enable-single'!). Also, some optimization flags were added to
hopefully make it faster.
This issue was found thanks to Zahra Sharbaf and Hamed Altafi.
This fixes bug #56588.
|
|
Until now, we were letting the TeXLive installer use the default
CTAN-chosen mirror based on the host. But in many cases, this is not
efficient and sometimes those servers don't work.
With this commit, we manually set the server to use (`rit.edu'), which is
relatively fast and up to date. In this way, until we build TeXLive from
source, every user will be using the same CTAN mirror.
|
|
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.
|
|
On some Fedora systems, libffi installs under `lib64', not `lib'. As a
result, Python's Setuptools can't find it and will not built (complaining
about not finding the `_ctypes' module).
With this commit, we fix this problem by explicitly putting a copy of
libffi's installed libraries within the `lib' directory.
This issue was found while testing the pipeline with Elham Saremi and Hamed
Altafi.
|
|
Until now, we weren't explicitly setting the C and Fortran compiler
environment variables (`CC' and `F77'). As a result, if the user's system
had already set them, there would be a problem (and the system's compilers
would be used).
With this commit, we are explicitly setting these two environment variables
at the start of `high-level.mk'.
This bug was found after a discussion with Elham Saremi.
|
|
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'.
|
|
There was only a conflict with `.file-metadata'.
|

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.
|
|
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
|
|
TIDES is an ODE integrator with multiple-precision arithmetic.
|
|
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.
|
|
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.
|
|
The comment above Gnuastro's build rule is not longer relevant, so it has
been removed.
|
|
The new command-box wasn't being rendered properly, so another correction
is made here. I also added the prompt `$' sign in another box of commands.
|
|
After checking the previous commit on Gitlab (to see how it is rendered), I
noticed that the code has come in the same line, not as a sperate
box. Hopefully this commit will fix it.
|
|
It is useful to visually see how the building of software is progressing
when running configure. I have been using a simple Bash `while' loop for
this, so I added it in the `README-hacking.md' to be useful for others too.
|

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).
|
|
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).
|
|
Until now, for some reason, the permission flags of `top.mk' were 755 (good
for an executable), not 644 (which is what they should be for a plain text
file that is run by another program).
This is corrected with this commit.
|
|
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).
|
|
Until now, TeXlive would only attempt to download/update LaTeX packages,
but after some time, it will be necessary for it to update itself. When
this happens, it complains about running it with `update --self'.
To fix this problem, before installing/updating the LaTeX packages, we will
first update tlmgr in any case.
Also, we weren't removing the TeXlive package version file before appending
the values to it. So it was just repeating the packages every time it was
updated. With this commit, it is being removed on every new build.
Finally, the version of Git was updated to its most recent version.
|
|
Until this commit, 'imfit' was installed using proper flags in order to
use our own libraries. However, it looks first of all to the default
system. As a consecuence, `imfit' program was linked to the host system
libraries, even when we told to use our own libraries!!
With this commit, the installation of `imfit' has been modified in order
to remove the default paths already set in the `SConstruct' script. By
doing this, only our paths are take into account for compiling the
program. It has been tested on Mac OS laptop and it works fine. Test on
GNU/Linux systems remain before merge into the main project branch.
|
|
Until this commit, `fftw' was building single precission float library
because `scamp' had problem on using the default double precission
library. However,`imfit' and maybe other programs will use double
precission float libraries.
With this commit, `fftw' installation is done twice in order to build
single and double precission float libraries. It does not complain and
goes up to the end without crashing. However, more tests are needed in
order to ensure that there is not problem on having both libraries
because in principle, they share the same header file and that could
cause problems.
|
|
`cfitsio' was recently updated and it cames up with a problem when
trying to build shared libraries (on Mac OS system laptop). This is
because the `configure' script for building `cfitsio' include by default
`rpath'.
With this commit, this issue is fixed by modifying the installation of
`cfitsio'. Using `sed', each ocurrence of `@rpath' in `configure' is
replaced by `$(ildir)'. Once it has been done, the installation of
`cfitsio' goes as normal.
In this commit, the version of the `cfitsio' has been also updated to
the most recent one.
|
|
With this commit, I have corrected a typo in the installation of
`imfit'. In principle it is working on Mac OS system but when I tried to
install it in GNU/Linux system it crashed. It complains about a problem
with the `cfitsio' library:
/pathto/libcfitsio.a: error adding symbols: File format not recognized
As in the last commits done by Mohammad in the project, `cfitsio'
installation has been upgraded and also the installation has been
modified, I am going to try this new version. I will also check if it is
a problem about dynamic/static library.
It also seems that the installation is taking libraries and variables
from the host system, so I will check that everything used is from our
own programs/libraries.
|
|
Until now, CFITSIO had several peculiar features which needed special
attention: 1) Its tarball didn't have a `.' in the version name and would
sometimes have extra `0's. 2) When unpacked it was just `cfitsio'. 3) It
hard coded the directory to search for cURL library. All of these forced us
to do a lot of extra steps for CFITSIO.
So I got in touch with them and fortunately they were very open to
correcting these issues and with version 3.47 all such issues have been
addressed in the tarball. Thanks to these changes, with this commit,
CFITSIO's build rule is now very similar to many other programs.
I also noticed that it has an optional `--with-bz2' feature to enable
unpacking `.fits.bz2' files. So this feature is also added.
|
|
Until this commit, `imfit' paper was not included into the
acknowledgements.
With this commit, a bib tex file for `imfit' has been added. So, now it
is properly cited into the final paper.
|
|
With this commit, `imfit' has been included into the project. As described
in the official webpage (http://www.mpe.mpg.de/~erwin/code/imfit/):
Imfit is a program for fitting astronomical images -- especially images
of galaxies, though it can in principle be used for fitting other
sources.
This program uses the `scons' program to build itself (not the traditional
GNU `configure' and `make' system). I have tested it by using an example
that can be found in the `examples' directory of the decompressed
tarball. It works fine without any error on my Mac OS system.
|
|
With this commit, SCons has been included into the project. As in the
official webpage of this program says:
SCons is an Open Source software construction tool—that is, a
next-generation build tool. Think of SCons as an improved,
cross-platform substitute for the classic Make utility with integrated
functionality similar to autoconf/automake and compiler caches such as
ccache. In short, SCons is an easier, more reliable and faster way to
build software.
The motivation for including this software into the project is because
there are some software that use this system for the installation. In
particular, the necessity of installing it comes from Imfit. This is an
astronomical software that uses this system so that is why it has been
included into the project. In principle it is simple, and I have tested
it on Mac OS sytem without any problem.

|
Until this commit, the name of the decompressed tarball directory of
PyYAML Python package was wrong. It has to be `PyYAML-version' instead
of `pyyaml-version'. When I run the installation on Mac OS system it
went up to the end of the installation with no error. However, when I
tried to install it on a GNU/Linux system, it complained about no
finding the `pyyaml-version' directory, which is the expected because
the name was wrong!
With this commit, I have fixed this issue by writting correctly the name
of the decompressed tarball directory.
|
|
With this commit, PyYAML Python package has been added into the project.
It is widely used in the Python community and the goal is to have human
readable configuration files. As in the web page
(https://pypi.org/project/PyYAML/) says:
YAML is a data serialization format designed for human readability and
interaction with scripting languages. PyYAML is a YAML parser and
emitter for Python.
|
|
With this commit, LibYAML library has been added. This library is a
prerequisite of the Python package PyYAML, which is widely used in the
Python community when configuration scripts are needed.
|
|
By default (when you run `make' within CFITSIO), it only builds a static
library. So until now, the template would only install a static version of
this library.
To be more clear about which libraries are used during the linking of
programs that use CFITSIO, it would be helpful to have shared library
versions also. Also, if the system has problems with static libraries (like
macOS systems), then it won't go looking outside the template to link with
them (these paths are hardcoded in the linker, which we don't build on
macOS and just use the system's tools).
With this commit, we are explicity running `make shared' in the CFITSIO
installation to have shared CFITSIO also. I also removed the old `static'
element (which we don't use anymore in any of the programs and have to
remove some time later!).
