Ok: Opengl-ffi.lpr loads fine and running lesson-14 shows the window with the fonts and moving text fine. Loading Cloucell.lpr insteads gives a few errors still (not many at all): *Error Part1* ; While compiling CELLS-TIME-REPORT in c:\dvx\cells\debug.lisp: Warning: EXCL::TIME-REPORT should be given exactly 9 arguments. It was given 8 arguments. Problem detected when processing (EXCL::TIME-REPORT CPU-GC-USER CPU-GC-SYS ...) inside (BLOCK CELLS-TIME-REPORT (TRC "cpu-gc-user" CPU-GC-USER) ...) inside (PROGN (BLOCK CELLS-TIME-REPORT (TRC "cpu-gc-user" CPU-GC-USER) ...)) *Error Part2* in "structure-view" Error: No class named: EXCL::STRUCTURE-EFFECTIVE-SLOT-DEFINITION. [condition type: PROGRAM-ERROR] *Error Part3* Cannot find c:\dvx\cello\lesson6.lisp. Will skip and continue compiling project. and that's it. Ah by the way in cloucell.lpr you still refer to "c:\\dev\\cello\\*whatever*" rather than "c:\\dvx\\cello\\*whatever*". _________________________________________________________________ Add photos to your e-mail with MSN 8.
