[petsc-users] Using real and complex matrices together

[Povolotskyi, Mykhailo]

Hi Evan,

I’m one of those users, who has multiple shared libraries.

It is quite stable since I create wrappers around the PETSc functions and hide the native PETSc symbols.

But, yes, the interoperations are not possible.

Michael.

It is not supported, sorry.  Some users do it with careful linking via
multiple shared libraries, but that is fragile and doesn't interoperate.
