# Written and placed in public domain by Jeffrey Walton
# This script builds GetText and friends from sources.

# GetText is really unique among packages. It has circular dependencies on
# iConv, libunistring and libxml2. build-iconv-gettext.sh handles the
# iConv and GetText dependency. This script, build-gettext-final.sh,
# handles the libunistring and libxml2 dependencies.
#
# The way to run these scripts is, run build-iconv-gettext.sh first.
# That bootstraps iConv and GetText. Second, run build-gettext-final.sh.
# That gets the missing pieces, like libunistring and libxml support.
#
# For the iConv and GetText recipe, see
# https://www.gnu.org/software/libiconv/.
#
# Here are the interesting dependencies:
#
#   libgettextlib.so: libiconv.so
#   libgettextpo.so:  libiconv.so, libiunistring.so
#   libgettextsrc.so: libz.so, libiconv.so, libiunistring.so, libxml2.so,
#                     libgettextlib.so, libtextstyle.so
#   libiconv.so:      libgettextlib.so
#   libiunistring.so: libiconv.so

# iConv has additional hardships. The maintainers don't approve of
# Apple's UTF-8-Mac so they don't support it. Lack of UTF-8-Mac support
# on OS X causes other programs to fail, like Git. Also see
# https://marc.info/?l=git&m=158857581228100. That leaves two choices.
# First, use a GitHub like https://github.com/fumiyas/libiconv.
# Second, use Apple's sources at http://opensource.apple.com/tarballs/.
# Apple's libiconv-59 is really libiconv 1.11 in disguise. So we use
# the first method, clone libiconv, build a release tarball,
# and then use it in place of the GNU package.
