cmus missing dependencies

[nerdling (Jeremy Lavergne)]

cmus looks for ffmpeg, among others, at startup and fails to find them. they're not listed as dependencies:

cmus: Error: dlopen(/opt/local/lib/cmus/ip/ffmpeg.so, 2): Library not loaded: /opt/local/lib/libavformat.dylib

Two of them are straightforward: libmodplug and libmpcdec. not sure where libavformat comes from but it might very well be ffmpeg like i assumed.

Which version of cmus do you have installed and with which variants? Do you happen to have uninstalled ffmpeg, libmodplug, libmpcdec since you installed cmus? I don't have modplug nor ffmpeg and hence, no ffmpeg.so or modplug.so were built.

2.3.3, default variants.

None of those packages were installed by or before cmus, so there was nothing to uninstall :-)

I removed autodetection in the configure phase (r72055). However, the .so should not have been built if you don't have the dependency. Anyway, is it OK now?

[nerdling (Jeremy Lavergne)]

Okay, here's the short of what happened: I installed one of the archives I had previously built of cmus. At the time, said ports must have been installed so it built them.

Ports that magically adapt based on what you have installed are a bad thing. I had this issue working on KDE: you should never build differently depending on the environment, force the configuration instead. That is, configure should say ffmpeg/libmodplug/libmpcdec are enabled or disabled like you added in the last revision.

Those changes should address the issue! Thanks.

So you indeed uninstalled those ports since the build of cmus. But yes, it was my fault for not seeing those new configure options for detecting libraries I don't have. Thanks for your report.
