petsc version 3.3 not compatible with slepc version 3.2

[Amy.Troschinetz@…]

As of r94054 petsc has been upgraded to 3.3, however slepc 3.3 has not been released yet and the current version, 3.2, is not compatible with the new version of petsc. petsc is a dependency of slepc.

Confirmed by Satish Balay on the petsc-maint@… mailing list:

for petsc-3.3 - you need slepc-dev [as the corresponding slepc-3.3 is not yet released]

I'm not sure if you can tell macports to use slepc-dev instead of slepc-3.2 [which is compatible with petsc-3.2 - but not petsc-3.3]

The compile error, stemming from a file which includes <slepceps.h>:

The latest release of slepc, 3.2-p5, seems to compile fine with petsc 3.3. I committed an update. Can you check if this works for you too?

[Amy.Troschinetz@…]

After pulling the update I'm not getting the error anymore. Seems to compile fine now!

[Amy.Troschinetz@…]

Sorry, I was mistaken. I'm still getting errors. Here is a minimal test example:

test.cpp:

#include <slepceps.h>
int main() { }

I'm using clang++ here because it seems to generate better error messages, however just for sake of completeness here's what g++ generates:

test.cpp:2: error: expected constructor, destructor, or type conversion before ‘int’

The problem seems to stem from the fact that PETSC_EXTERN_CXX_END is not defined. In version 3.3 of PETSc:

$ cd /opt/local/lib/petsc/include
$ grep -HIin "define PETSC_EXTERN_CXX_BEGIN" *
# no results

I have a backup on Time Machine of PETSc version 3.2:

$ cd /path/to/time/machine/backups/opt/local/lib/petsc/include
$ grep -HIin "define PETSC_EXTERN_CXX_BEGIN" *
petscsys.h:45:#define PETSC_EXTERN_CXX_BEGIN extern "C" {
petscsys.h:48:#define PETSC_EXTERN_CXX_BEGIN

Note that I am perfectly able to install slepc 3.2-p5 and PETSc 3.3 side by side using MacPorts... they're just not compatible with each other so when you start trying to use them things break down.

fixed in r96224 now that slepc 3.3 has been released.
