Hi, I'm trying to work out how to use 'copy-foreign-libs' [1], but not having much luck. I believe the implementation of the collection using ' copy-foreign-libs' is correct because it works in '#lang video', but I've been unable to use it myself.
I created a collection 'testffi-1' that would make use of the existing(known working) 'libvid-x86_64-macosx' package [2] used by `#lang video`. I installed 'testffi-1' with 'raco pkg install' , but attempts to call it with a short test program fail with an error that the foreign library cannot be found. Thinking that I hadn't 'provided'ed the foreign lib to my test script let me to create a 'main.rkt' in 'testffi-1', but that also fails to fine the foreign lib with the same error message, and using the DrRacket 'trace' functionality seems to blame 'kw.rkt' (/Applications/Racket v7.2/collects/racket/private/kw.rkt: 1325:47), which seems odd to me because the error is in my code, not in the standard racket libs. I used (require setup/dirs <https://docs.racket-lang.org/raco/dirs.html?q=get-lib-dirs>) to see if the foreign lib was included, but get-lib-search-dirs <https://docs.racket-lang.org/raco/dirs.html#%28def._%28%28lib._setup%2Fdirs..rkt%29._get-lib-search-dirs%29%29> returns /Users/spdegabrielle/Library/Racket/7.2/lib /Applications/Racket v7.2/lib when called from both the test script and the 'testffi-1' collection. Any suggestions on how I can test or resolve this issue would be appreciated.
