Yep — GYRE uses the ‘fpx3’ preprocessor, which helpfully writes out a dependency list (as Fortran comments) in the top of each source file it creates. I then use another script, ‘fpx3_deps’, to extract the dependency info and automagically create a make dependency list.

Both fxp3 and fpx3_deps are part of the MESA SDK (to allow GYRE to compile correctly). But for compiling MESA, it would probably be better to use a different tool that does dependency extraction without the pre-processing. 

cheers,

Rich
