I'm a little surprised the cygblas-0.dll (x86_64, 0.2.12-1) does not appear to be linked to libgfortran. Were you seeing your test executables using multiple cores? I think you may have to build with USE_THREAD=1 to enable threading (or USE_OPENMP=1 for openmp)? I may be doing this wrong, but I'm getting errors from your openblas build, but not the reference blas package, when I run the following: $ curl -O https://raw.githubusercontent.com/xianyi/OpenBLAS/develop/test/sblat2.f $ gfortran -o sblat2 sblat2.f -lblas $ rm -f SBLAT2.SUMM $ curl https://raw.githubusercontent.com/xianyi/OpenBLAS/develop/test/sblat2.dat | ./sblat2 This outputs messages like: ** On entry to SGEMV parameter number 1 had an illegal value and so on for the other single-precision level 2 functions in that test. This does seem to work okay on Linux or an existing i686-w64-mingw32 build. -Tony -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
