Summary	0003174: leqm-nrt does not properly depend on libsndfile
Description	In packaging DCP-o-Matic for nixpkgs (Nix/NixOS), it was discovered that the leqm-nrt fork used does not properly link against libsndfile in some situations (such as the one invoked during Nix builds). The output ELF does not include the required "NEEDS" line for libsndfile, and hence the hooks in Nix do not make the package available at link time.
Additional Information	The following downstream patch to wscript resolves the issue: https://github.com/thetayloredman/nixpkgs/blob/e51b4a6b8d686cfd56723b7ba43ace703e6510f2/pkgs/by-name/dc/dcpomatic/leqm-nrt-libsndfile-linking.patch
Tags	No tags attached.

carl 2026-08-23 20:59 administrator ~0007361	Hi, thanks for the fix (and your work with nix!) I applied it to my leqm-nrt git repo. Let me know if I need to do anything else.
