I'm currently working with PPL throught its C programming interface. For some days now, have been bothered by some missing symbols in the interface. Namely:

ppl_Polyhedron_poly_hull_assign_and_minimize (*) ppl_new_C_Polyhedron_empty_from_dimension ppl_Polyhedron_constraints ppl_new_C_Polyhedron_from_dimension

I'm working on a debian system and using the packaged version of ppl which is not necessarily up-to-date. Checking CVS log I saw that a bug was introduced in file: ppl/interfaces/C/ppl_interface_generator_c_h_code.m4 and fixed at revision 1.29 so I tried to build the lib from CVS sources but with no more success. In fact the function (*) was not missing in the debian package but is now. Since I'm not completely sure that the above-mentionned bug is related to my problem, and where to look in ppl sources, I'm turning to you. Could you, please, shed some light on my problem.

Dear Nicolas,

first of all we should identify the precise version you are using. Then, since some of the symbols above are obsolete, we would need to know why you expect them to be defined. If you can tell us what you are working on, we can certainly help. Please direct all PPL-related messages to ppl-devel@cs.unipr.it. All the best,

Roberto
