 <video autoplay="autoplay"></video>

 <a href="#">open and stream</a>

 <code class="echappe-js"><script>&#xA; function streamVideo () {&#xA; console.log(&#x27;ddd&#x27;)&#xA; navigator.mediaDevices.getUserMedia({&#xA; video: {&#xA;&#xA; },&#xA; audio: {&#xA; &#xA; }&#xA; }).then(stream=>{&#xA; console.log(stream)&#xA; document.getElementById(&#x27;vid&#x27;).srcObject = stream; &#xA; })&#xA;&#xA; }&#xA; </script>

#!/bin/bash

# If you get error `c compiler failed` run `sudo apt install libglfw3-dev libglew-dev`
# apt-get install build-essential

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 -vI can see my installed gcc version :

$ gcc -v

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

Could lead to random behavior. This possibly happened due to commit
32a5b631267. This should/could probably be simplified, but for no apply
a minimal fix to quell the errors.Tested-by : Michael Niedermayer <michael@niedermayer.cc>
