Thank you, it worked (almost). Compilation is ok and openmp is properly taken into account. Unfortunately when I try the binary, an error occurs:
john --test
/usr/lib/libgomp.so.1: version GOMP_4.0 required by /usr/ports/security/john/work/john-1.7.9-jumbo-7/run/john not found
Of course.
/usr/lib/libgomp.so.1 is in the base system and provides GOMP_1.
/usr/local/lib/gcc5/libgomp.so.1 is installed with gcc5 port and provides GOMP_4.0.1.
I'll have to tweak settings at compile time to use library provided with gcc5 at runtime automatically. In the mean time, using LD_LIBRARY_PATH helps:
LD_LIBRARY_PATH=/usr/local/lib/gcc5 john --format=des --test
Benchmarking: Traditional DES [128/128 BS SSE2-16]... (2xOMP) DONE
