I think using the 2 --enable options together does it; when I do that in my out of source builds, I see a problem with unresolved externs too, though they're from the OCC libraries. - tim On 10/08/2010 04:22 PM, Robert Smith wrote:

Yes, this is an in source build. Also, I'm using --enable-shared and --enable-static to get both types of libraries out of the build. I'm not sure if that's a contributing factor.

I don't see this problem in parallel either. I've (double/triple/quadruple) checked I don't have any local mods. Can you try an autoreconf? Also, these are all out of source builds, is the one you're doing an in source build?

I don't see this problem, in serial at least (will try building in parallel next).

You're right it isn't explicitly in the link line.

It's defined as follows in the Makefile:

libiGeom_la_LIBADD = $(top_builddir)/libcgm.la

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?

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.

make[3]: Entering directory `/nfs/fathom/libs/cgm/cgm-4.0.1/parallel/

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.
