[Mypaint-discuss] scons - can't compile MyPaint, g++ options of unknown origin

2013-03-09 Thread Daniel Ziólkowski 
scons uses weird options causing compilation fail:
 -OPT:Olimit=0
and
 -march=core2 -O2 -fplugin=/usr/lib64/llvm/dragonegg.so

Second line is probably from /etc/portage/make.conf, but even after
commenting line with variable CFLAGS, these options are added.

The first one causes error:
 cc1plus: error: argument to ‘-O’ should be a non-negative integer
And the second:
 cc1plus: error: cannot load plugin /usr/lib64/llvm/dragonegg.so
 /usr/lib64/llvm/dragonegg.so: undefined symbol: tree_map_base_marked_p

What can be problem and how to fix it?

I'm using Gentoo with clang and
 CFLAGS=-march=core2 -O2 -fplugin=/usr/lib64/llvm/dragonegg.so
 CXXFLAGS=${CFLAGS}
in /etc/portage/make.conf

 CFLAGS=-march=core2 -O2 -fplugin=/usr/lib64/llvm/dragonegg.so
 CXXFLAGS=${CFLAGS}
 in /etc/portage/make.conf

The MyPaint scons file does neither add -OPT:Olimit=0 nor
-march=core2 -O2 -fplugin=/usr/lib64/llvm/dragonegg.so.
It will capture CFLAGS/CXXFLAGS from the environment, so please first
try to unset CFLAGS and unset CXXFLAGS before trying to build.
Furthermore, it will use cflags as specified by its dependencies in
their pkg-config files. So try to do pkg-config --cflags json-c
python gtk-2.0 lcms-2.0 (note: names of the dependencies are from my
head, check with the scons file for the exact names). Could also grep
your pkg-config files for this strange -OPT thing.

Hope that helps,
Jon
