If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

I think I have seen this before but got it fixed somehow. Maybe we need to force a modern compiler for zvbi?

[ryandesign (Ryan Carsten Schmidt)]

It's not immediately clear to me what the problem would be. ffmpeg does depend on pkgconfig and zvbi. zvbi does install zvbi-0.2.pc. Please attach the config.log.

Replying to ryandesign:

Ah, I guess this: #64212

Why does it have to be _not_ disabled for any platform? MacPorts avoids rpaths, AFAIK, and they are known not to work correctly on numerous instances.

[ryandesign (Ryan Carsten Schmidt)]

Ah yes. zvbi has -R/opt/local/lib in its zvbi-0.2.pc on 10.6 and later.

I agree with disabling rpath unconditionally, provided the build still succeeds on newer OS versions.

[kencu (Ken)]

this software should not use the “-R” flag at all on darwin.

zvbi has moved to ​https://github.com/zapping-vbi/zvbi and has had many updates since our version.

perhaps newer versions don’t use that “-R” flag any longer…
