Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

# Make it possible to pass version numbers extracted from a file in
|
|
# $(srcdir) to autoconf.
|
|
#
|
|
# Autoconf insists on passing the package name and version number to
|
|
# every generated .h file and every Makefile. This was a reasonable
|
|
# design at times when a version number was changed only once a month.
|
|
# Nowadays, people often assign a new version number once a week, or
|
|
# even change it each time a 'git' commit is made. Regenerating all
|
|
# the files that depend on configure.ac (aclocal.m4, configure,
|
|
# config.status, config.h, all Makefiles) may take 15 minutes. These
|
|
# delays can severely hamper development.
|
|
#
|
|
# An alternative is to store the version number in a file in $(srcdir)
|
|
# that is separate from configure.ac. It can be a data file, a shell
|
|
# script, a .m4 file, or other. The essential point is that the maintainer
|
|
# is responsible for creating Makefile dependencies to this version file
|
|
# for every file that needs to be rebuilt when the version changes. This
|
|
# typically includes
|
|
# - distributable documentation files that carry the version number,
|
|
# but does not include
|
|
# - aclocal.m4, configure, config.status, config.h, all Makefiles,
|
|
# - executables.
|
|
#
|
|
# autoconf and automake make it hard to follow this approach:
|
|
#
|
|
# - If AC_INIT is used with arguments, there is a chicken-and-egg problem:
|
|
# The arguments need to be read from a file in $(srcdir). The location
|
|
# of $(srcdir) is only determined by AC_CONFIG_SRCDIR. AC_CONFIG_SRCDIR
|
|
# can only appear after AC_INIT (otherwise aclocal gives an error:
|
|
# "error: m4_defn: undefined macro: _m4_divert_diversion").
|
|
# Furthermore, the arguments passed to AC_INIT must be literals; for
|
|
# example, the assignment to PACKAGE_VERSION looks like this:
|
|
# [PACKAGE_VERSION=']AC_PACKAGE_VERSION[']
|
|
#
|
|
# - If AC_INIT is used without arguments:
|
|
# Automake provides its own variables, PACKAGE and VERSION, and uses them
|
|
# instead of PACKAGE_NAME and PACKAGE_VERSION that come from Autoconf.
|
|
# - If AM_INIT_AUTOMAKE is used with two arguments, automake options
|
|
# like 'silent-rules' cannot be specified.
|
|
# - If AM_INIT_AUTOMAKE is used in its one-argument form or without
|
|
# arguments at all, it triggers an error
|
|
# "error: AC_INIT should be called with package and version arguments".
|
|
# - If AM_INIT_AUTOMAKE is used in its one-argument form or without
|
|
# arguments at all, and _AC_INIT_PACKAGE is used before it, with
|
|
# the package and version number from the file as arguments, we get
|
|
# a warning: "warning: AC_INIT: not a literal: $VERSION_NUMBER".
|
|
# The arguments passed to _AC_INIT_PACKAGE must be literals.
|
|
#
|
|
# With the macro defined in this file, the approach can be coded like this:
|
|
#
|
|
# AC_INIT
|
|
# AC_CONFIG_SRCDIR(WITNESS)
|
|
# . $srcdir/../version.sh
|
|
# gl_INIT_PACKAGE(PACKAGE, $VERSION_NUMBER)
|
|
# AM_INIT_AUTOMAKE([OPTIONS])
|
|
#
|
|
# and after changing version.sh, the developer can directly configure and build:
|
|
#
|
|
# make distclean
|
|
# ./configure
|
|
# make
|
|
#
|
|
# Some other packages use another approach:
|
|
#
|
|
# AC_INIT(PACKAGE,
|
|
# m4_normalize(m4_esyscmd([. ./version.sh; echo $VERSION_NUMBER])))
|
|
# AC_CONFIG_SRCDIR(WITNESS)
|
|
# AM_INIT_AUTOMAKE([OPTIONS])
|
|
#
|
|
# but here, after changing version.sh, the developer must first regenerate the
|
|
# configure file:
|
|
#
|
|
# make distclean
|
|
# ./autogen.sh --skip-gnulib
|
|
# ./configure
|
|
# make
|
|
#
|
|
|
|
# gl_INIT_PACKAGE(PACKAGE-NAME, VERSION)
|
|
# --------------------------------------
|
|
# followed by an AM_INIT_AUTOMAKE invocation,
|
|
# is like calling AM_INIT_AUTOMAKE(PACKAGE-NAME, VERSION)
|
|
# except that it can use computed non-literal arguments.
