Re: [racket] Detecting 32/64-bit racket

Another not so great way, in Racket, to tell if the current racket is built as a 64 bit or 32 bit executable (is that what you're wanting?) ;; 64bit? : -> boolean (define (64bit?) (eq? (expt 2 61) (expt 2 61))) I don't know if this is promised to always work going forwards, but it is hard for

[racket] Detecting 32/64-bit racket

Greetings. Is there a recommended way to detect whether racket is a 32- or 64-bit executable? I'm writing a racket extension to wrap a C library , and in the configure.ac, I want to be able to detect whether racket is a 32- or 64-bit executable, so I kn
