[petsc-users] Cannot find a C preprocessor OSX

This code is a bit convoluted..
There is CPP, CPPFLAGS, CXXCPP, CXXCPPFLAGS. But then no FPP or FPPFLAGS..
And then base.py has: [which is wrong for 'Cxx', 'FC'?]
def getPreprocessorFlagsName(self, language):
if language in ['C', 'Cxx', 'FC']:
flagsArg = 'CPPFLAGS'
elif language == 'CUDA':
flagsArg = 'CUDAPPFLAGS'
else:
raise RuntimeError('Unknown language: '+language)
return flagsArg
And config/compile/FC.py has [which reuses CPP,CPPFLAGS for FC]:
class Preprocessor(config.compile.C.Preprocessor):
'''The Fortran preprocessor, which now is just the C preprocessor'''
def __init__(self, argDB):
config.compile.C.Preprocessor.__init__(self, argDB)
Matt - should we have FPP,FPPFLAGS supported here?
Perhaps using CPPFLAGS with FC is a bug? So we should atleast do:
diff --git a/config/BuildSystem/config/compile/FC.py b/config/BuildSystem/config/compile/FC.py

return
And then [I'm not sure where this gets used..]
