https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227438 Bug ID: 227438 Summary: -fopenmp=libgomp doesn't work Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: toolchain@FreeBSD.org Reporter: jbeich@FreeBSD.org libomp has limited platform availability (currently, only i386 and amd64), so ports/ may prefer to use another library to avoid ugly conditionals. Using GCC isn't always an option due to conflicts in libgcc_s, libstdc++, broken ASAN and hard to use with LLD. Steps to reproduce: $ pkg install ca_root_nss gcc7 $ fetch https://computing.llnl.gov/tutorials/openMP/samples/C/omp_hello.c $ cc -fopenmp=libgomp -isystem$(find /usr/local/lib/gcc7 -name omp.h | xargs dirname) -L/usr/local/lib/gcc7 omp_hello.c Actual result $ ./a.out Hello World from thread = 0 Number of threads = 1 Expected result: $ ./a.out Hello World from thread = 4 Hello World from thread = 0 Number of threads = 8 Hello World from thread = 2 Hello World from thread = 1 Hello World from thread = 6 Hello World from thread = 5 Hello World from thread = 7 Hello World from thread = 3 -- You are receiving this mail because: You are the assignee for the bug.
