error 'couldn't open "libgirepository-1.0.dylib" '

[spdegabrielle]

Hi,

Firstly - thank you for making #lang overscan - it is much appreciated and I look forward to twitch streaming some coding sessions using it.

I have found that Overscan fails to find libgirepository-1.0.dylib.

When I run:

#lang overscan
(broadcast (videotestsrc)
           (audiotestsrc)
           (filesink "/dev/null"))

DrRacket returns:

Welcome to DrRacket, version 7.2 [3m].
Language: overscan, with debugging; memory limit: 2048 MB.
. ffi-lib: couldn't open "libgirepository-1.0.dylib" (dlopen(libgirepository-1.0.dylib, 6): image not found)

Interactions disabled: overscan does not support a REPL (no #%top-interaction)

I understand if you have moved on from this project. I'm going to persist in trying to get it working and will submit a PR if I'm successful.

If you can offer any advice it would be appreciated.

Kind regards,

Stephen

• Another language, #lang video (a DSL for editing videos), uses(require ...) to get dependencies via the package https://github.com/videolang/native-pkgs (see https://github.com/videolang/video/blob/testing/info.rkt ) - maybe this is a better approach than brew
