SlepcHasExternalPackage#

Determine whether SLEPc has been configured with the given package.

Synopsis#

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

Not Collective

Input Parameter#

  • pkg - external package name

Output Parameter#

  • has - PETSC_TRUE if SLEPc is configured with the given package, else PETSC_FALSE

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”, “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.
