#include "slepcsys.h" 
PetscErrorCode SlepcHasExternalPackage(const char pkg[], PetscBool *has)

Not Collective

Input Parameter#

  • pkg - external package name

Output Parameter#

Notes#

This is basically an alternative for SLEPC_HAVE_XXX whenever a preprocessor macro is not available/desirable, e.g., in Python.

The external package name pkg is, e.g., arpack or primme. It should correspond to the name listed in ./configure --help.

The lookup is case insensitive, i.e. looking for ARPACK or arpack is the same.
