I am building ffmpeg/x264 on Windows 10.
Have built 64-bit successfully.
The 32-bit configuration gives
"Host Compiler lacks C11 support"
Gcc version is 14.2.0 and should have c11 from wah
This is how I set up the environment to compile.
Installed msys2-x86_64-20250221.exe
In the UCRT64 command window:
- pacman -S git
- pacman -S mingw-w64-i686-toolchain
- pacman -S mingw-w64-x86_64-toolchain
- pacman -S base-devel
- pacman -S yasm
- pacman -S nasm
- mkdir /src
- cd /src
In mingw32:
- git clone http://git.videolan.org/git/x264.git
- git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
- cd x264
- make clean
- ./configure --prefix=/mingw32 --enable-shared --disable-cli
--disable-gpl --enable-lto --host=i686-w64-mingw32
- make -j8
- make install
- cd ../ffmpeg
- As we have a license I edit ./configure: move libx264 from
EXTERNAL_LIBRARY_GPL_LIST to EXTERNAL_LIBRARY_LIST
- make clean
./configure --prefix=/mingw32 --enable-shared --disable-static
--disable-programs --disable-lzma --disable-doc --disable-sdl2
--enable-libx264 --disable-debug --host=i686-w64-mingw32
Error:
"Host Compiler lacks C11 support"
ffmpeg version 7.1.1.1 and also from git March 15
built on Windows 10
