Calling Fortran Blas routine from C

Hello,

I am trying to call Fortran subroutine that calls zdotu from C.

I am using linking flags from Advisor https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/

These linking flags for both C and Fortran work when I compiled samples dgemm and matrix multiplication.

However, I am getting SIGSEGV, when running my simple app when both Fortran and C linking flags are used.

I am using GNU compiler, Intel OpenMP lib, intel64 platform, sizeof(int)=4, tried both dynamic and static linking.

The code I am trying to run is actually from R configure script.

Please let me know, how to link both Fortran and C at the same time.
