[Pkg-electronics-devel] Bug#1098791: kicad: Please include patch to link against libatomic on powerpc

[John Paul Adrian Glaubitz]

Source: kicad
Version: 9.0.0+dfsg-1
Severity: normal
Tags: patch
User: debian-powerpc at lists.debian.org

Hi,

src:kicad currently fails to build from source due to missing linking against libatomic:

[ 34%] Linking CXX executable bitmap2component
cd /build/reproducible-path/kicad-9.0.0+dfsg/debian/build/bitmap2component && /usr/bin/cmake -E cmake_link_script CMakeFiles/bitmap2component.dir/link.txt --verbose=1
/usr/bin/ld: ../common/libcommon.a(wx_view_controls.cpp.o): undefined reference to symbol '__atomic_fetch_add_8@@LIBATOMIC_1.0'
/usr/bin/ld: /lib/powerpc-linux-gnu/libatomic.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

This can be fixed by patching debian/rules to append -latomic to DEB_LDFLAGS_MAINT_APPEND:

Please see the attached patch. I have also included armel, m68k and sh4 in the
architecture list as this should also be necessary on these architectures.

PS: Would be nice if kicad could be built for any architecture.

Thanks,
Adrian
