Custom Solver _PYMFIX=ON

MFiX
#1

Building a custom solver for the Silane Pyrolysis example. Getting an error about ENABLE_PYMFIX=ON. Do I have to deactivate it? and if so how? (I couldn’t find any similar flag, yet). Thanks

Building custom solver for SP2D.mfx
Running cmake command:

Unfortunately, the interactive solver (Fortran wrapped with python) only works with GNU Fortran Compiler. If you need to build with the Cray compiler, follow these instructions for the batch solver: https://mfix.netl.doe.gov/doc/mfix/18.1.5/user_manual/howto/batch_solver.html

You can also build the solver from the source using cmake. See the documentation here: https://mfix.netl.doe.gov/doc/mfix/18.1.5/user_manual/developers/index.html

thanks!
after you msg I realized the actual problem. I am on a Cray system and although I had GNU module loaded the Cray one was superseding. I unloaded it and interactive build completed smoothly.
