We could support both 6.3 and 6.5 by writing some configure logic to detect the version and then using #ifdef's in the code. The question is whether or not we *want* to support both 6.3 and 6.5. One reason we might want to is that Ubuntu includes binary packages for OCC 6.3. - jason

Hi, Jed Thanks for working on OCC6.3 to OCC6.5 migration issue, your patches have been applied to build CGM on OCC6.5. As to your question, since Opencascade doesn't support compatibility of OCC6.3 and OCC6.5, CGM won't be able to support it either. Which means your patches are necessary for migrating CGM from OCC6.3 kernel to OCC6.5 kernel.

The dynamic libraries in Cubit have path references to one another that are relative to subdirectories the Cubit.app bundle, and I think it might be complicated to convince these libraries to work with one another when loaded from an executable outside of the app bundle. Dynamic library loading works somewhat differently on OSX than on Linux, and I'm not as familiar with it, so I don't whether there's something I'm overlooking. I'll give it a try with OCC next week. ~S > > On 04/07/2011 10:48 AM, Steve Jackson wrote: >> On Apr 7, 2011, at 10:24 , Tim Tautges wrote: >> >>> On 04/07/2011 09:21 AM, Avery Bingham wrote: >>>> I have a few questions on installing MeshKit. >>>> >>>> First, has it been installed on a Mac?

I spent some time trying to build CGM (merge-cubit12 branch) against Cubit 12.2 on Mac OS 10.6, and I got nowhere: I cannot find a way to successfully link against the libcubiti19 file that's inside in the Cubit application. (I can convince the linker to link against this file, but I cannot reference any symbols without producing undefined symbol errors.) This prevents CGM from passing its configure step. >> >> I haven't time to work on this further, but if anyone with a Mac wants to look at this more closely, they can contact me for details about what I've tried so far. >> >> (Would it be practical to set up MeskKit to build without CGM, or with a CGM that doesn't have a geometry backend installed?
