# Libraries
# ---------
#
# We would prefer to build static libraries, but some compilers like LLVM
# don't have static capabilities, so they'll only build dynamic/shared
# libraries. Therefore, we can't use the easy `.a' suffix for static
# libraries as targets and there are different conventions for shared
# library names.

# Until version 0.11.0 is released, we are using the version corresponding
# to commit 014954db (603 commits after version 0.10.0, most recent when
# first importing log4cxx into this project).
#
# Note that after cloning the project, the following changes are necessary
# in `configure.ac'.
#  - Update the final name of the tarball and its version (from `git
#  - describe') by modifying the `AC_INIT' line:
#        AC_INIT([apachelog4cxx], [0.10.0-603-014954db])
#  - Because of the long file names in the project, some files will not be
#    packaged by default, so pass the `tar-ustar' option to Automake (the
#    `AM_INIT_AUTOMAKE' line of `configure.ac':
#        AM_INIT_AUTOMAKE([foreign subdir-objects -Wall tar-ustar])
#
# You can then simply bootstrap the project and make the distribution
# tarball like this:
#        ./autogen.sh && ./configure && make -j8 && make dist-lzip
#
# Unfortunately we have to re-run the `autogen.sh' script on the tarball to
# build it because it will complain about the version of libtool, so until

# Libraries with special attention on Mac OS
# ------------------------------------------
#
# Libgit2 and WCSLIB don't set their installation path, or don't do it
# properly, in their finally installed shared libraries. But since we are
# linking everything (including OpenSSL and its dependencies) dynamically,
# we need to also make a shared libraries and can't use static
# libraries. So for Mac OS systems we have to correct their addresses
# manually.
#
# For example, Libgit2 page recommends doing a static build, especially for
# Mac systems (with `-DBUILD_SHARED_LIBS=OFF'): "It’s highly recommended
# that you build libgit2 as a static library for Xcode projects. This
# simplifies distribution significantly, as the resolution of dynamic
# libraries at runtime can be extremely problematic.". This is a major
# problem we have been having so far with Mac systems:
# https://libgit2.org/docs/guides/build-and-link
# On macOS system, `libgit2' complains about not finding `_iconv*'
# functions! But apparently `libgit2' has its own implementation of libiconv
# that it uses if it can't find libiconv on macOS. So, to fix this problem
# it is necessary to use the option `-DUSE_ICONV=OFF` in the configure step.
