That works perfectly now. I have another question regarding accessing the quadrature information. When I use PetscFEGetQuadrature(), then PetscQuadratureView(), I see what I expect regarding point locations, weights. However, when I try to use PetscQuadratureGetData() the pointers seem to point to random memory locations. The exact line from my test problem is: call PetscQuadratureGetData(quad,q_nc,q_dim,q_num,pq_points,pq_weights,ierr); where the pq_* are the pointers giving strange output. The q_nc, q_dim, and q_num are all giving what I would expect to see. You are clearly the first Fortran user interested in this stuff ;) Handling of arrays in Fortran demands some more work from us. I need to write a wrapper for that function. I will do it as soon as I can. Thanks, Matt Happy to send along the file if that helps.

I recently updated my PETSc and am now getting the following error during compile/linking on an existing application: Undefined symbols for architecture x86_64: "_petscfecreatedefault_", referenced from: _MAIN__ in fe_test.o ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status make: *** [dist/fe_test] Error 1 I'm running Mac OS X Yosemite (10.10.5). I've created a "minimum working example" (attached) that re-creates the problem. It's basically just dm/impls/plex/examples/tutorials/ex3f90, but tries to create a PetscFE object. Everything goes fine and the DM looks like what is expected if PetscFECreateDefault is commented out. Any idea what am I missing? Yes, I had not made a Fortran binding for this function. I will do it now. I have merged it to the 'next' branch, and it will be in 'master' soon. Thanks, Matt Thanks, Matt Many thanks!
