Hello everybody !!!! I have been spending hours on the same Cython problem, which I hope you can solve instantly :-)
I have a Cython file, which happens to be sage/numerical/mip_coin.pyx which defines the following function : cdef float osi_solve(self,c_OsiSolverInterface * si,bool log,bool objective_only) I would like to use this function outside of mip_coin, so I wrote in this other file : cimport sage.numerical.mip_coin from mip_coin cimport osi_solve Well, everything seems to be fine in this other module, though when Sage compiles mip_coin.pyx, it looks at its .pxd file and notices the following line : cdef float osi_solve(self,c_OsiSolverInterface * si,bool log,bool objective_only) Well, this is (I hope) perfectly normal. As I want to be able to use this function outside, I have to declare it in the .pxd... But then Cython tell me the following thing : /usr/local/sage/devel/sage-cplex/sage/numerical/mip_coin.pxd:88:20: Non-extern C function 'osi_solve' declared but not defined So it sounds like Sage does not find the declaration of osi_solve even though it is made in mip_coin.pyx Please, tell me that you know where it comes from :-) Nathann -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
