A lot of values need to be increased in gdata.h and elsewhere (e.g., MAX_EQN) when the chemical mechanism becomes too large. It would be great if KPP would use dynamic memory allocation depending on the size of the chemical mechanism. This is probably a big task, and I don't think I will be able to do it. However, I've created this issue so we can discuss this.

Thinking about this feature again, I fear that it won't be possible in C. For the time being, I guess we'll have to recompile KPP every time we reach one of the limits.

I've added the milestone 4.0.0 to this issue.

Bug fix: Make sure FIX is the 2nd arg to Fun in gckpp_Integrator.F90
63e3fa2 
KPP/carboncycle/gckpp_Integrator.F90
- Added a kludge: In routine FunTemplate, we now pass FIX (and not VAR)
  as the 2nd argument to Fun.  This error was causing the F variable
  within Fun to be corrupted, which was propagating negatives through
  the code.
- NOTE: We have patched this file for KPP 2.5.0, but a final fix will
  be issued in KPP 3.0.0.  We will eventually rebuild all mechanisms
  with KPP 3.0.0 anyway.
- See KineticPreProcessor/KPP#6 for more info.
