[petsc-dev] Are there both a function AND a #define to retrieve PETSc version?

[Barry Smith]

  Eric,

   We don't have this but I guess we could add some support.

   Do you need the actual versions or would a single check be all you need such as

   PetscLibrarySubminorVersonMatchsIncludeSubminorVersion() and PetscLibraryMinorVersonMatchsIncludeMinorVersion() ?

   If we were willing to make PetscInitialize() a macro we could even do

#define PetscInitialize(a,b,c,d)  (PetscLibraryMinorVersonMatchsIncludeMinorVersion() || PetscInitialize_Private(a,b,c,d))  

:-(

BTW: it looks like PETSC_VERSION_PATCH is not used anymore and it has been replaced with PETSC_VERSION_SUBMINOR
