Thanks, that indeed helped. Now I am getting different errors during the make command. Could you take a look at it please? First first guess is that maybe the newer `icpx` does not work with FreeFEM, and I should go back to `icpc`.

It works, I’m using `icpx` for about two years. Again, this is specific to your installation/machine.

Here is a successful compilation of `FreeFem++` with `icpx`.

Thanks for looking into it! I will look into it whether I did not mix modules up, and talk to the sysadmin for machine specific help.
