I have added a togl opengl canvas widget into MUVES for a new results viewer. On linux and irix, this viewer works fine. However, on osx, it will compile but not run.
Using the BRLCAD tcl libraries to build the MUVES shared library, it dies with a NULL main window error, and it appears the interp structure passed to Muves_Init is corrupted as it is being passed to that function.
However, if I build my own tcl libraries (tcl/tk 8.4.15, itcl/itk3.3, iwidgets 4.0) then the added widget works, although using wish instead of bwish causes other problems.
