(sorry about the possible duplicate; I sent this from the wrong email address...)
Hey there! I found a bug in the `opengl` package. (Not the sgl bindings! The opengl you get by doing raco pkg install opengl) Since http://pkg.racket-lang.org is down, and because there's no authorship information in the README or info.rkt, I can't find the maintainer of the `opengl` package. (Jay perhaps?) Since it's likely that they're reading the mailing list, I'll just send it to everyone via the "shotgun responsibility" approach :) Problem: (load-shader-source shader port) strips newlines from each line in the port. This has consequences: any shaders that start with a #version proeprocessor definition fail with "preprocessor error: syntax error, unexpected IDENTIFIER, expecting NEWLINE", and shaders that contain comments also fail similarly. Fix: Replace the load-shader-source function with the following: (define (load-shader-source shader port) (let* ((lines (for/vector ((line (in-lines port))) (string-append line "\n"))) (sizes (for/list ((line (in-vector lines))) (string-length line))) (sizes (list->s32vector sizes))) (glShaderSource shader (vector-length lines) lines sizes))) Note the (string-append line "\n"). Hope that helps! ____________________ Racket Users list: http://lists.racket-lang.org/users
