  fate : use an even more exotic channel layout mov-mp4-pcm-float test
  The old layout happened to be a native layout and therefore missed some
  
  recently fixed layout parsing bugs.

• ffmpeg build fails with gcc error even with gcc installed (C compiler test failed)

  15 mars 2023, par Martin

  I am on macos 11.2.3, trying to build ffmpeg in my terminal. When I run my script sh buildffmpeg.sh which is below :

  


  #!/bin/bash

# If you get error `c compiler failed` run `sudo apt install libglfw3-dev libglew-dev`
# apt-get install build-essential
# apt-get build-dep ffmpeg
# when running this on mac, you need to install some libraries such as 'brew install opus'

  It fails with this error :

  


  > sh buildffmpeg.sh

Extracting...
Building...
gcc is unable to create an executable file.
C compiler test failed.

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 "ffbuild/config.log" produced by configure as this will help
solve the problem.


  


  I have been trying to solve this error, and have installed gcc with brew, if i run gcc -v I can see my installed gcc version :

  


  $ gcc -v
Using built-in specs.

  So if gcc is installed correctly (i think) why is it failing with a gcc error when I build ffmpeg ?
