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:
