main.log

It's saying that gnutls is not being recognized using pkg-config. The log also says that macports thinks that gnutls is installed.

However, I can't reproduce the problem here so may be something specific to your installation.

/opt/local/var/macports/build/_opt_macports_trunk_dports_multimedia_ffmpeg/ffmpeg/work/config.log should show more detail about what the problem is. Please attach.

Also please make sure that gnutls is properly installed and that /opt/local/lib/pkgconfig/gnutls.pc exists.

What does

pkg-config --libs --cflags gnutls

return?

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_multimedia_ffmpeg/ffmpeg/work/ffmpeg-2.5.3/config.log

[wangsix (Cheng-i Wang)]

pkg-config --libs --cflags gnutls

returns

Package zlib was not found in the pkg-config search path.
Perhaps you should add the directory containing `zlib.pc'
to the PKG_CONFIG_PATH environment variable
Package 'zlib', required by 'gnutls', not found

and /opt/local/lib/pkgconfig/gnutls.pc exists.

Thank you, the config.log file is attached.

[dbevans (David B. Evans)]

Is zlib installed?

$ port installed zlib
The following ports are currently installed:
  zlib @1.2.8_0 (active)

and /opt/local/lib/pkgconfig/zlib.pc ?

[dbevans (David B. Evans)]

Note that config.log also shows the problem is missing zlib.

check_pkg_config gnutls gnutls/gnutls.h gnutls_global_init
pkg-config --exists --print-errors gnutls
Package zlib was not found in the pkg-config search path.
Perhaps you should add the directory containing `zlib.pc'
to the PKG_CONFIG_PATH environment variable
Package 'zlib', required by 'gnutls', not found
ERROR: gnutls not found using pkg-config

Anonymous:~ User$ sudo port installed zlib
The following ports are currently installed:
  zlib @1.2.8_0+universal (active)

but /opt/local/lib/pkgconfig/zlib.pc does not exist. After reinstall via

sudo port install zlib

The file zlib.pc exists.

Then retry install ffmpeg via

sudo port clean ffmpeg
sudo port install ffmpeg

get the following

The new main.log is attached. (main 2.log)

[dbevans (David B. Evans)]

Per the log, error this time is

:info:configure ERROR: libass not found using pkg-config

So you may need to do the same with it.

However, this all looks like something is definitely not right with your ports installation. These errors are saying the the ports in question are installed but not all expected files are available (.pc files for instance).

If you continue to run into this sort of problem, you may need to remove MacPorts completely and reinstall to make sure you have a consistent installation.

Have you recently upgraded your OS from another version? If so did you follow the ​Migration instructions?

[wangsix (Cheng-i Wang)]

After repeat the similar process. Finally the ffmpeg is installed.
