Hi, I tried the following file as a prelude to doing conditional compilation and ran into the following snag,
----------------------------- example.scm ----------------------- (define A #t) (define B 'undefined) (if A (set! B 'good) (set! B 'bad)) (print B) ------------------------------ end ---------------------------------- running csi prints out the expected message 'good' compiling using 'csc example.scm' and running the executable results in 'undefined' being printed. the code generated by 'csc -t example.scm' is given below. BTW I would dearly like to get objc egg to compile.
