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.
