undefined reference to LAPACKE_***
Sat Nov 18 18:20:00 GMT 2017
Â so I am using a cmake and it is of the format:
set(BLAS_LIB "/usr/lib/libblas.so") for my ubuntu system,
which I changed it to:
set(BLAS_LIB "/usr/lib/libblas.a") for the cygwin.
If I set the set(LAPACK_LIB "/usr/lib/liblapacke.a") it complains that
it doesn't exist, since as you also said this package doesn't exist in
Cygwin. So in my code I am calling at some point functions like the
LAPACKE_zlange and there is the issue. I guess I cannot use them in
Cygwin, and I will have to change it to FORTRAN calls
