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.

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. (I shouldn't assume that the condition was left exclusively to ensure it is not fixed for 10.6 on ppc, lol.)

[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.

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…
