--- Comment #19 from Maxime Boissonneault <maxime.boissonneault at calculquebec dot ca> --- Hi again, I notice in the first line that leads to an error of bits/c++config.h not found : /software6/src/gcc-4.8.2-build/./gcc/xgcc -shared-libgcc -B/software6/src/gcc-4.8.2-build/./gcc -nostdinc++ -L/software6/src/gcc-4.8.2-build/x86_64-unknown-linux-gnu/libstdc++-v3/src -L/software6/src/gcc-4.8.2-build/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -B/software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/bin/ -B/software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/lib/ -isystem /software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/include -isystem /software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/sys-include -c -O2 -march=native -pipe -Wall -D_GNU_SOURCE -std=c++98 -fno-exceptions conftest.cpp I see that /software6/compilers/gcc/4.8.2/include/c++/4.8.2/x86_64-unknown-linux-gnu/ is not listed in the -isystem. Shouldn't it be there ? This is where the bits/c++config.h should be found. On the other hand, a couple of paths are given as -isystem argument that do not exist : /software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/include /software6/compilers/gcc/4.8.2/x86_64-unknown-linux-gnu/sys-include Those folders do not exist.
