Bug#1125347: webkit2gtk: Please build with GCC options to avoid OOM issues on 32-bit targets
Source: webkit2gtk
Version: 2.50.4-1
Severity: normal
User: debian-powerpc@lists.debian.org
Usertags: m68k hppa powerpc sh4

Hi,
on hppa, powerpc and sh4, the build fails due to GCC running out of memory [1]:
FAILED: [code=1] Source/WebCore/CMakeFiles/WebCore.dir/__/__/WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-40.cpp.o
/usr/bin/c++ -DBUILDING_GTK__=1 -DBUILDING_WEBKIT=1 -DBUILDING_WITH_CMAKE=1 -DBUILDING_WebCore (...)
-c /build/reproducible-path/webkit2gtk-2.50.4/build-soup3/WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-40.cpp
virtual memory exhausted: Cannot allocate memory
After reading through the ReduceBuildMemoryOverhead article [2] on the Debian wiki,
I discovered the option "-no-integrated-cpp" which helps work around the OOM issue
above. Together with the "--param ggc-min-expand=10" option, the build suceeds:

endif
But since armhf and i386 don't run out of memory, I suggest to use the workaorund on
hppa, m68k, powerpc and sh4. For sh4, an additional patch is required to disable the
musttail attribute.
Thanks,
