Re: [racket-dev] Problem with planet and Windows shortcuts
To catch up the list: Antonio sent me more information, and the problem is that Racket was handling symbolic links but not junctions (which are a different kind of link on Windows). Antonio: I've pushed a repair to handle junctions, so let me know if it works for you.

Re: [racket-dev] Working Cairo-bindings for Racket?
No, I'm suggesting that while I think a real binding to cairo would be a good idea, it should be based on the code already in racket/draw and that the code in my library is probably useless. Feel free to use any of it that you find useful, though.

In any case, at least I realized that (require racket/draw/unsafe/cairo-lib) followed by (define libcairo cairo-lib) is (just ?) a more portable way of saying: (define libcairo (ffi-lib "libcairo")) [Or in Windows: (define libcairo (ffi-lib "libcairo-2")) because it is called libcairo-2.dll] Like this: #lang racket (require racket/draw/unsafe/cairo-lib) (require ffi/unsafe) cairo-lib # > (define libcairo (ffi-lib "libcairo")) . . ffi-lib: couldn't open "libcairo.dll" (The specified module could not be found.; errno=126) > (define libcairo (ffi-lib "libcairo-2")) > libcairo # > (eq? cairo-lib libcairo) #t > So I guess making my own set of bindings shouldn't be too much of racket-science...
