no c compiler found libx264 build [closed]
24 août 2012, par kerim yucelI have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.
However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.
Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.
Any help will be appreciated. Thanks a lot.
P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.
Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.
Another edit :
I have tried this code and obtained the following.echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?

1 exit status 1I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.
