because a simple platform dependency in gimpcoreconfig.c doesn't do
the trick (there can be both manual builds and bundled builds on
windows and macos). Use an AC_DEFINE() instead.
Also, make sure the system gimprc and its manpage are generated with
the correct values.
Some gimprc properties' default values depend on the machine where
"make dist" in run. We had an ugly hack in place to force
(num-processors 1) in the installed system gimprc and its manpage, but
were still leaking "tile-cache-size" and "mypaint-brush-path".
The files are generated by the hidden options --dump-gimprc-system
and --dump-gimprc-manpage which exist only for this purpose.
In gimpconfig-dump.c, special case the three properties in
dump_gimprc_system() and dump_gimprc_manpage() to output constant
default values for "num-processors" and "tile-cache-size" and
output @mypaint_brushes_dir@ in "mypaint-brush-path" which can
be replaced at configure time.
Also introduce etc/gimprc.in so @mypaint_brushes_dir@ can actually be
substituted for the installed system gimprc.
This was hard-coded to what I guess was a personal prefix (commit
368c7c0511), which is obviously wrong. This has to be constructed at
compilation and the man must mirror whatever is the actual installation
path of mypaint-brushes package.
I hesitated keeping both the pkg-config and freetype-config (which is
mostly a wrapper to pkg-config nowadays apparently) as fallback, but
anyway I can see in their repositories that they have a pkg-config file
since 2003. Really I don't think it makes sense to hold onto such old
and deprecated dependency configuration systems.
Move gimp-debug-tools.c from tools/ to a new app-tools/ subdir,
which should contain external tools needed by app/, and which is
built *after* app/ (unlinke tools/). This allows gimp-debug-tool
to depend on libapp and libappwidgets, instead of on actual source
files from app/. Building sources from app/ in another subdir
screws with the distclean rules, and breaks distcheck.
If running for instance in a cross-compilation, I need to make clearer
the fact we are looking for a native GEGL and also that we are looking
for the executable (used during the build), not the library. This is a
different test as the one for the library with PKG_CHECK_MODULES (which
looks for the target platform's library).
gimp_spawn_async() is similar to, but more limited than,
g_spawn_sync(). Unlike the latter, gimp_spawn_async() uses
vfork(), instead of fork(), when possible.
On Linux, a process that uses large amounts of memory (as GIMP may)
can hang during a fork() if overcommitting is enabled, and there's
not enough memroy. Using vfork() avoids that, since it doesn't
duplicate the parent's address space.
On Linux, when /proc/sys/kernel/yama/ptrace_scope is 1, a process
may only ptrace its descendants by default, which prevents the GDB
process spawned by gimp_stack_trace_print() from attaching to, and
producing a backtrace for, the calling process.
Use prctl() with PR_SET_PTRACER, when available, in the parent
process, to allow the child process to ptrace it.
In a previous commit, I bumped it for Windows only, where major bugs had
been fixed in recent fontconfig. Yet as Mitch notes, Debian testing has
Fontconfig 2.12.6, so we can simply use the same requirement on all
platforms. No need to make our configuration script over-complicated
with per-platform requirements here.
Fontconfig has a new slowness issue, this time apparently because of
locked cache files, preventing a successful cache update.
See: https://bugs.freedesktop.org/show_bug.cgi?id=99360
Furthermore the slowness apparently happens at every GIMP startup, and
also even when GIMP closes according to various reports. So let's bump
Fontconfig version (for Win32 builds only).
Also let's not make it a recommendation anymore, but a requirement. That
makes quite a few Win32-specific fontconfig bugs which have been fixed,
and most are quite serious so this should not be considered as optional
anymore, I guess.
It is nice because when available (Linux only?), it is a lot faster than
using a dedicated debugger such as GDB or LLDB, and also it allows to
always have a backtrace, even when no debuggers are installed.
Unfortunately the output is a lot less detailed, with no file paths, no
line numbers (even when debug symbols are there), no local values
printout, etc. It's pretty bare, with function names and the stack
levels. This is why it is not given priority, and GDB and LLDB are still
preferred when available.
I completely forgot to rename the appstream file according to the new
ID. While doing so, I also make it a .in.in file, with initial
processing by the autotools. Indeed I need @GIMP_COMMAND@ to be replaced
by AC_CONFIG_FILES().
Finally I fix a badly closed XML tag (which reminds me I should always
test a commit, even when it's a simple non-C 1-liner change!).
This makes no functional differences since this package has a pkg-config
file only since 0.4.7, our current requirement. This means that
searching for any poppler-data through pkg-config is the same as
searching for this minimum version.
But at least that makes for better output in case of error. People who
wish to build GIMP will have proper error information of the minimum
requirement for poppler-data.
This ensures that MyPaint default brushes are installed, otherwise this
makes the MyPaint brush tool quite useless and confusing unless MyPaint
is installed (which was making MyPaint a de-facto dependency of GIMP
until this commit!). Also we won't have to guess anymore the right path
for these brushs. The path will be known at compile time.
Since they are both mandatory dependencies now, no need to do a nested
check anymore. Also I was getting some weird warnings in the configure
output (maybe also because of missing square brackets?), which are
coincidentally fixed this way as well.
So it seems that [[]] are needed to quote the command part of
AC_CONFIG_COMMANDS(), in particular when square brackets are used inside
the command (which is our case since we used sed with regex classes []).
It is not even in the docs of AC_CONFIG_COMMANDS() but I found this
information in the docs of the deprecated AC_OUTPUT_COMMANDS()!

By default, autoconf only takes care of po/POTFILES, not any
po-*/POTFILES. The file contents has to go in po-*/Makefile, after
running `config-status`, step which was consequently not properly done.
And last consequence is that `make update-po` in any po-*/ was quite
broken. Now things should be better.
In configure.ac, add --enable-windows-installer option (off by
default), which should be set to generate the necessary files for
the installer translations during the build. Using this option is
only supported when building from git, since the installer files
are not included in source tarballs.
Rename setup.isl.desktop.in to setup.isl.in, and instruct intltool
to treat it as an .ini file explicitly.
Delete generated message files during make clean.
Use intltool for managing the translations for the Windows
installer, instead of manually maintaining the translated message
files.
The message files are generated in the source directory, under
build/windows/installer/lang, as part of the build, and can be
subsequently used to build the installer, as before.
It never belonged inside "tools". Also rename its "pdb" subdirectory
to "groups". This had to happen before 2.10 so cherry-picking between
branches doesn't become a nightmare in the future.
This variable is used for the MimeType key in the desktop file, which
allows to know if a software can open a file with the Exec key command.
Whether GIMP can also export such format is not to be taken into
consideration.
Poppler and poppler-data are now hard dependencies.
PDF is a common-enough format nowadays that import support is likely
considered as a granted feature by everyone. Moreover the current
fallback to the PostScript plug-in for PDF support just gives a degraded
experience with less features (and probably a lot of bugs since
basically nobody uses this code).
Poppler-data is also considered mandatory because non-western language
support should never be considered an "option". People using non-western
languages are not second class citizens and therefore if we say that PDF
import is now a hard feature, it should also include PDF using CJK or
Cyrillic languages.
