Follow-up Comment #98, bug #44478 (project octave):

Well, there aren't that many common global variables that are present in both
libraries (i.e., common name, both of which have a "T" alongside it),
discounting the glXYZ family which I think are just table entries:


000000000004ba00 T _glapi_create_table_from_handle
000000000028b2c0 T _glapi_create_table_from_handle

0000000000019cb0 T _init
000000000004e748 T _init


There are a few cases where the function might be in OSMesa lib referenced by
GL lib.  (Why it would go that direction, I don't know.  Where would these
functions come from if OSMesa were not linked in?  Is that a conflict?)


                 U _glapi_check_multithread
00000000002a5840 T _glapi_check_multithread

                 U _glapi_get_dispatch_table_size
00000000002a5770 T _glapi_get_dispatch_table_size

                 U _glapi_get_proc_address
00000000002a5680 T _glapi_get_proc_address

                 U _glapi_get_proc_offset
00000000002a5640 T _glapi_get_proc_offset

                 U _glapi_set_context
00000000002a5850 T _glapi_set_context

                 U _glapi_set_dispatch
00000000002a5860 T _glapi_set_dispatch


My guess would be that the conflict lies with one of the above routines.  I
could send this to the OSMesa discussion list and see what they say.  (I'll
make sure I have the absolute latest of all code to see if these names may
have changed.)
