Okay, I've tried from /gpfs/home/HCBG142/axs02/lxc83-axs02/gcc-5.2.0/build: ../configure --build=powerpc64-bgq-linux-gnu --host=powerpc64-bgq-linux --prefix=/gpfs/home/HCBG142/axs02/lxc83-axs02/gcc5 --with-gmp=/gpfs/home/HCBG142/axs02/lxc83-axs02/aux/gmp --with-mpfr=/gpfs/home/HCBG142/axs02/lxc83-axs02/aux/mpfr --with-mpc=/gpfs/home/HCBG142/axs02/lxc83-axs02/aux/mpc and make reports the same error: Markus, I assume that --disable-libgomp disables OpenMP and that is not an option, I need OpenMP. The config.log under libgomp shows this error: configure:3657: /gpfs/home/HCBG142/axs02/lxc83-axs02/gcc-5.2.0/build-up/./gcc/\ xgcc -B/gpfs/home/HCBG142/axs02/lxc83-axs02/gcc-5.2.0/build-up/./gcc/ -B/gpfs/\ home/HCBG142/axs02/lxc83-axs02/gcc5/powerpc64-bgq-linux/bin/ -B/gpfs/home/HCBG\ 142/axs02/lxc83-axs02/gcc5/powerpc64-bgq-linux/lib/ -isystem /gpfs/home/HCBG14\ 2/axs02/lxc83-axs02/gcc5/powerpc64-bgq-linux/include -isystem /gpfs/home/HCBG1\ 42/axs02/lxc83-axs02/gcc5/powerpc64-bgq-linux/sys-include -V >&5 xgcc: error: unrecognized command line option '-V' xgcc: fatal error: no input files compilation terminated.
