Hi Bill,
PETScSolver.C should be also recompile by cg???.
So, according to your message, I should change the cg makefile in a way that
buildEquationSolvers.C is recompile during cg compilation?. Because so far I'm
just copying these two files (PETScSolver.C and buildEquationSolvers.C ) from
the overture installation dir.
HAve a nice day,
Joel

Hi Joel,
Your error message is different now since Oges cannot find PETScNew
(which
is the parallel PETSc solver)
> Oges::buildEquationSolvers:ERROR: solver PETScNew is not currently
available
Check the file Overture/oges/buildEquationSolvers.C to see where this
error
occurs. You may need to recompile this file. A new version of this file
should be
compiled by cg with the compile flag -DOVERTURE_USE_PETSC, and this
new version over-rides
the version that is in the Overture library.

this is driving me nuts. With the serial version of cg ins I don't have

present and also all the required libraries. I also checked the shared
library dependencies and the executable is proper linked to the petsc
libraries. At this point I dont know what could be the problem, do I need
to change something in the source code in order to have the parallel
petsc solver ????
