[petsc-dev] [Suggestion] Configure QOL Improvements

[Faibussowitsch, Jacob]

I think Jed is referring to the fact that configure appears to do all of these checks after doing the compiler, MPI, MathEnv, etc which take a long time. The change would be to check missing external library dependencies before even doing the compiler checks.

Best,

Jacob

You can verify that Z works in a fraction of a second, but building X
may take minutes.  Work bottom up, verify everything that is given
before building anything.

That is exactly what we do now. What are you talking about?
