How can I tell which options PETSc was compiled with?

Question

I'm working on a machine with a version of PETSc compiled by someone else. Is there a straightforward way to find out which options were used at compile time from the installation itself? For example, is there a file that has all of the compile time options that is generated by make?

Try looking inside the Makefile and files which it includes. — milancurcic, Dec 16 '11 at 22:38

There are a few ways to do this:

Check $PETSC_ARCH/conf/reconfigure-$PETSC_ARCH.py (where $PETSC_ARCH is expanded, i.e. for me that is 'arch-c')
Depending on which information you want, you could use make getlinklibs or make getincludedirs
Also, you could check $PETSC_ARCH/include/petscconf.h for all the standard #ifdef's that PETSc was configured with

For lower level information, the file $PETSC_ARCH/conf/petscvariables has everything defined for make (there are some generated rules in petscrules), but Sean is right that looking in the reconfigure script is best. – Matt Knepley Dec 18 '11 at 23:42

In the source directory, there is a log file to record every output of the screen including the commands has been input.
