I installed Fortran Intel Parallel Studio XE 2018. I am trying to compile a fortran program on my macbook using and but I am getting undefined symbols for blacs package. I read that blacs are already installed as part of the Intel Math Kernel library. Can someone help me with some pointers?
source /opt/intel/bin/compilervars.sh -arch intel64 -platform mac
user@system:~/Downloads/test$ ifort test.f

Hi Jakes,
If you get "Undefined symbol error message" that probably caused by your link line, you have to specify link with MKL libraries. Please use MKL link advisor help you to generate compiling & linking line. Thanks.
Best regards,
Fiona
