[petsc-users] error of compiling complex

[Satish Balay]

Is there a reason you can't use petsc build tools?

config/gmakegen.py processes the mkaefiles in source dirs - and determines the list of files to build [for a given configure setup]

src/ksp/pc/impls/tfs/makefile has:

#requiresscalar real

i.e the sources in this dir are compiled only when --with-scalar-type=real and not when --with-scalar-type=complex etc..
