ffmpeg @4.2.1 +nonfree: Install fails on Catalina 10.15.1

[beremour]

I have fresh Catalina 10.15.1 and empty MacPorts 2.6.2 installation. FFmpeg is the very 1st port to install. I'll attach log file.

ld: unexpected token: !tapi-tbd-v3 file '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/lib/libSystem.tbd' for architecture x86_64

please try installing the cctools port and then try against with a clean install attempt.

[cjones051073 (Chris Jones)]

Correction. Please make sure you have the ld64 port installed, and that it is using the Xcode variant, i.e.

 > port installed ld64
The following ports are currently installed:
  ld64 @3_1+ld64_xcode (active)

[cjones051073 (Chris Jones)]

Note, with the above ffmpeg +nonfree builds fine for me on 10.15.

[beremour]

Thank you very much for help! It was not obvious for me to install ld64 first. Is it common practice for every fresh MacPorts install ?

Success scenario:

sudo port -fp uninstall installed
…
sudo port -fp clean all
…
port installed
No ports are installed.

port variants ld64
ld64 has the variants:
   ld64_127: Use ld64-127 as the default linker (last version that supports ppc and works on Leopard)
     * conflicts with ld64_236 ld64_97 ld64_xcode
   ld64_236: Use ld64-236 as the default linker (last version that builds against OS X's libstdc++)
     * conflicts with ld64_127 ld64_97 ld64_xcode
   ld64_97: Use ld64-97 as the default linker (last version that works on Tiger)
     * conflicts with ld64_127 ld64_236 ld64_xcode
   ld64_xcode: Use ld64-xcode as the default linker (version provided by the selected Xcode.app toolchain)
     * conflicts with ld64_127 ld64_236 ld64_97

Use -h to get full help or, even better, run 'man ffmpeg'

Glad that helped. No, its not normal to need it, but it often helps. I think in this case adding it as a build dep makes sense.

[Chris Jones <jonesc@…>]

In 98d0e83811a621b23b65593d07a21614a1e22715/macports-ports (master):

ffmpeg: Add ld64 as build dep
Closes: #59604

[beremour]

Is it just "ld64" build dep, or "ld64 +ld64_xcode" build dep ?

[ryandesign (Ryan Carsten Schmidt)]

It doesn't seem like this is an ffmpeg-specific problem, and surely the ld64 dependency is not needed on older systems. And it's not clear that it's still needed on Catalina either, because the logs provided here are old: they show clang > 1099 being blacklisted, which has already been removed from the port in favor of using the xcode_workaround portgroup, whatever that does.
