• ffmpeg install fail OSX 10.7.2

  3 mars 2012, par egermano

  Can you help me ?

  I try to install a ffmpeg using a brew, but i can't.

  It seems like the dependencies was successfully installed.

  I am using a Mac OSX 10.7.2 and the XCode 4.2.1.

  I couldn't install ffmpeg.

  I've tried :

  brew install ffmpeg
  
  brew install --use-clang ffmpeg
  
  brew install --use-clang --HEAD ffmpeg

  And they've all failed.

  This is the result log.

  $ brew install --use-clang ffmpeg

  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.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  ==> /usr/bin occurs before /usr/local/bin
  
  This means that system-provided programs will be used instead of those
  
  provided by Homebrew. This is an issue if you eg. brew installed Python.
  
  
  
  Consider editing your .bashrc to put:
  
    /usr/local/bin
  
  ahead of /usr/bin in your PATH.
  
  Some brews install binaries to sbin instead of bin, but Homebrew's
  
  sbin was not found in your path.
  
  
  
  Consider editing your .bashrc to add:
  
    /usr/local/sbin
  
  to the PATH variable.
  
  
  
  Some "config" scripts were found in your path, but not in system or Homebrew folders.
  
  
  
  `./configure` scripts often look for *-config scripts to determine if software packages
  
  are installed, and what additional flags to use when compiling and linking.
  
  
  
  Having additional scripts in your path can confuse software installed via Homebrew if
  
  the config script overrides a system or Homebrew provided script of the same name.
