[Chicken-users] Another easyffi problem

[William Ramsay]

Now I have another problem with easyffi.    The screen comes up 
correctly, but the program fails with
callbacks.

The old version (and the examples still on the web) used:

/* the ___callback marker is needed, because gtk_main() may
  (*and* will) call Scheme callbacks. */
___callback void gtk_main()/;
/


But this now fails in compile because ___callback is no longer valid.   
If you take it out the code still works until
you hit a callback.   Then you get the following:

        callback invoked in non-safe context - execution terminated

Again, I'm missing something that's changed.
