CGM inner workings are still mysterious to me :( . When we build cgm "with cubit" we are using ACIS geometry engine from cubit libraries. What we build in cgm is just a small interface. With occ, the interface we build is bigger.<br>Jane and Tim have probably better explanations.<br>This is the message I got 2 years ago from Jason: (he meant to "build cgm", not cubit). GME and GQE are geometry modeling engine, respective geometry query engine.<br><br>"It won't work to build cubit with both acis and occ support if the acis
support is from linking against cubit. It is very unlikely that such a
configuration would be stable. If the GME and GQE interfaces are stable
it might work a little better to build only the OCC subdir in that case.<br><br>Iulian Grindeanu <<span class="Object" id="OBJ_PREFIX_DWT1264_com_zimbra_email"><span class="Object" id="OBJ_PREFIX_DWT1265_com_zimbra_email">iulian@mcs.anl.gov</span></span>> wrote:<br><br>>Yes, good point.<br>>Right now, I have a separate CGM build with occ, and one for cubit (actually, more, for cubit-12, parallel, serial, etc)<br>>Does anybody regularly build with both?<br>><br>>I have some strange errors when I build CGM with both, that do not appear when I build just with occ, or just with cubit.<br>>...<br>>./.libs/libiGeom.a(iGeom_CGMA.o): In function `igeom_load_':<br>>iGeom_CGMA.cc:(.text+0x631): undefined reference to `CGMParallelComm::CGMParallelComm(int, int*)'<br>>iGeom_CGMA.cc:(.text+0x67c): undefined reference to `CGMReadParallel::CGMReadParallel(GeometryQueryTool*, CGMParallelComm*)'<br>>iGeom_CGMA.cc:(.text+0x6ae):

You said<br><br>> You cannot configure with cubit and occ at the same time.<br><br>and I was curious: what causes the limitation? I understood from the CGM paper that models from multiple geometric kernels could be loaded at once in order to perform joint modeling; is it just the combination of cubit and OCC/OCE that cause trouble?<br><br> Thanks,<br> David<br><br></blockquote><br></div></body></html>
