Description Andrew Savchenko gentoo-dev

Hello,

galaxy-2.2 suffers from underlinking with -lpthread:

i686-pc-linux-gnu-g++ -march=native -m32 -O2 -funswitch-loops -fpredictive-commoning -Wl,-O1,--as-needed -pipe galaxy.o zfuncs.o `pkg-config --libs gtk+-3.0` -o galaxy       
/usr/lib/gcc/i686-pc-linux-gnu/4.7.3/../../../../i686-pc-linux-gnu/bin/ld: zfuncs.o: undefined reference to symbol 'pthread_create@@GLIBC_2.1'

Can be fixed by adding -lpthread to the compilation command.

galaxy-2.2-pthread.patch

Fix underlinking with pthread. This also moves pthread CFLAGS modification from ebuild to Makefie patch, because we need to patch anyway.

galaxy-2.2.ebuild.patch

Apply patch and remove flags mangling because it is moved to the ebuild.
