  • How to fix the "No working C compiler found." problem for compiling x264 in Linux ?

    27 février 2023, par gc xu

    Firstly I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I git clone the source code from https://code.videolan.org/videolan/x264.git.
Then, I run command ./configure, it shows

    


    ./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
No working C compiler found.


    


    I check the file "config.log". It shows :

    Plus I wonder is there something to do with nasm ? Becasuse I install nasm with some C grammer problems :

    I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I want to install x264 to configure it in ffmpeg. Thanks for all your answers !
