OK, I have now largely succeeded in getting vasilis's cells-gtk running under AllegroCL with UFFI as the FFI. Some rough edges remain, but with lambda-gtk now out there (also on c-l.net) I feel like getting back to Cello for OS X.
I plan to move vasilis's original CLisp-only source into the cells-gtk project and make the UFFI version a separate module because I was really hacking/slashing and have probably created some issues which should not be allowed to ruin Vasilis's fine work.
As for Cello OS X, all library tests are functional under OpenMCL: Glut, FTGL/FreeType, OpenAL, ImageMagick, and of course OpenGL. Tomorrow I will try to resurrect the Fabulous Spinning Shape Demo.
Then I port back to win32 under AllegroCL and maybe Lispworks. With that done I will hunker down with cvs and try to sort out the mess in the repositories. I plan to make Cells just be Cells again, put cells-gtk source under the cells-gtk project, then move everything else back into the Cello project. (I know.) If anything, things like cl-magick and cl-openal stand a chance of getting their own projects, perhaps even cl-opengl and cl-ftgl. But that is down the road.
After that I want to try text-to-speech, perhaps by going directly at OS-specific libraries instead of looking for a C project (Festival?) already portable. That or something to read some standard XML or VRML model format so things can be designed in a proper tool and then pulled into Cello.
