I'm not sure if this is really a CFFI issue or not, but when I'm trying to use the gtkairo backend for McCLIM (which uses CFFI) I get the following: * (clim-demo::run-test 'clim-demo::demodemo) debugger invoked on a SIMPLE-ERROR in thread #<THREAD "initial thread" {B28F279}>: Trying to access undefined foreign variable "_gdk_error_warnings". Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. restarts (invokable by number or by possibly-abbreviated name): 0: [ABORT] Exit debugger, returning to top level. (CFFI::FOREIGN-SYMBOL-POINTER-OR-LOSE "_gdk_error_warnings") 0] Is this a CFFI issue? Cheers, CY __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
