Hello, as discussed with sleep deprived guys on IRC, I'm having trouble binding libcdd.a. I designed a minimalistic example that show my problem. It builds fine, but fails at sage startup (during import) with the following error: ImportError: /usr/local/sage/local/lib/python2.5/site-packages/sage/geometry/pymcdd.so: undefined symbol: dd_set_global_constants
The example is attached as a patch against sage 3.2.3. As burcin pointed on IRC, this might have something to do with the fact that dd_set_global_constant is mangled: nm local/lib/libcdd.a | grep dd_set_global_constants 00000185 T _Z23dd_set_global_constantsv However, I don't know how I should interpret it... I would be very glad if someone had look at this. Thanks ! Sebastien Here are the logs from the build and the import. ## building ################################################################## $ sage -b ---------------------------------------------------------- sage: Building and installing modified Sage library files.
