It looks your link doesn't have "libcgm" in the link library list after "libiGeom", but I don't know why. Can you tell me how your "libiGeom_la_LIBADD" in itaps directory is defined? Hong-Jun ----- "Robert Smith" <[email protected]> wrote:

Has anyone encountered a problem building a parallel version of CGM with OCC (the patched version)? This is built on the new Ubuntu 10 release installed on the ANL compute servers (thrash specifically). It is using MPI compiled with

GCC 4.4.3.

The issue comes during make check. It first appears in the src/itaps

directory when building chaman. But it occurs in all 3 link steps taken in that directory.

The log lines for the compile and link are below.

I've looked at .libs/libiGeom.so. It does have undefined references to

the above routines. But it also has a dependency on the libcgm.so.0

shared library that exists in the main CGM source directory (in .libs). And that shared library has definitions for the routines.
