--- Comment #8 from LE GARREC Vincent <legarrec.vincent at gmail dot com> --- Thanks, you're right. I was able to build with CFLAGS="-march=native -ggdb2 -g2 -pipe -fno-omit-frame-pointer -O0" CXXFLAGS="-march=native -ggdb2 -g2 -pipe -fno-omit-frame-pointer -O0" but with adding : export CFLAGS_FOR_TARGET="-O2 -g" export CXXFLAGS_FOR_TARGET="-O2 -g"
