I'm trying to get cells3 + Celtk up and running on sbcl/linux, and I found three issues: (i) in utils-kt/core.lisp, defmacro export!: sbcl does not like the export at compile time: `(eval-when (#-sbcl :compile-toplevel :load-toplevel :execute) (ii) in Celtk/run.lisp, defun run-window: (CG:kill-splash-screen) ---> CG is an unknown package for me. This is Allegro Common Graphics, I assume? I changed that to #+allegro (CG:... (iii) in Celtk/tk-interp.lisp, the names do not match the latest tcl/tk. Something with :or would work better: (define-foreign-library Tcl (:darwin (:framework "Tcl")) (:windows (:or "Tcl85.dll")) (:unix (:or "libtcl.so" "libtcl8.5.so.0" "libtcl8.5.so" "libtcl8.4.so.0" "libtcl8.5.so")) (t (:default "libtcl"))) (define-foreign-library Tk (:darwin (:framework "Tk")) (:windows (:or "Tk85.dll")) (:unix (:or "libtk.so" "libtk8.5.so.0" "libtk8.5.so" "libtk8.4.so.0" "libtk8.4.so")) (t (:default "libtk"))) (define-foreign-library Tile ;(:darwin (:framework "Tk")) (:windows (:or "tile078.dll")) (:unix (:or "libtk.so" "libtk8.5.so.0" "libtk8.5.so" "libtk8.4.so.0" "libtk8.4.so")) (t (:default "libtk"))) HTH someone, Peter
