> What compiler option did you use to compile BLAS and LAPACK?
It is mentioned on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29621#c0:
1. Build blas:
gfortran -c BLAS_SRC\*.f -O3
ar -r libblas.a *.o
2. Build lapack:
gfortran -c LAPACK_SRC\*.f -O3
ar -r liblapack.a *.o
... which means the (default) optimization options as provided by -O3 only.
