[QUESTION] Using Custom KPP Mechanisms in GC 12.9.3

[JFBrewer]

Hi folks,

I'm still working in GC 12.9.3 for a little while longer, and I wanted to make a custom mechanism for some comparison work. Unfortunately, as far as I can tell, the CMake setup for KPP in 12.9.3 doesn't appear to be set up to allow for the creation of Custom mechanisms.

“Custom” is not included as a valid mechanism in /CMakeScripts/GC-ConfigureClassic.cmake, and there is no corresponding CMakeLists.txt file within /KPP/Custom for it to run even if I add the option to do so within /CMakeScripts/GC-ConfigureClassic.cmake. I tried to replicate the CMakeLists.txt from /KPP/SOA_SVPOA/, but was unable to produce compilable code - I mostly just got odd errors appearing throughout the rest of the code anywhere GC tried to reference KPP subroutines.

In the end, I was successful in getting the model to compile by simply copying my Custom.eqn file into /KPP/SOA_SVPOA and compiling within that framework, but this is obviously not the preferred solution. I'm posting here in case anyone has already solved this issue, but mostly I'm aiming to create a record.

Thanks,
Jared
