Trouble building ffmpeg with cuda for windows 32 with visual studio 2022
27 juillet 2022, par manouHere is my building process


I open mingw32 from the x64 Native Tools Command Prompt for VS 2022


then in the mingw32 shell :


# cd /
# ./c/Program\ Files/Microsoft\ Visual\ Studio/2022/Community/VC/Auxiliary/Build/vcvars32.bat
# cd ~
# pacman -Sy diffutils git make gcc yasm pkg-config --noconfirm
# git clone --depth 1 https://git.ffmpeg.org/ffmpeg.git ffmpeg 
# git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git nv-codec-headers 
# cd nv-codec-headers/
# make PREFIX=/usr/local
# make install PREFIX=/usr/local
# cd ..
# mkdir nv_sdk
# cp -r /c/Program\ Files/NVIDIA\ GPU\ Computing\ Toolkit/CUDA/v11.7/lib/Win32/* nv_sdk
# cp -r /c/Program\ Files/NVIDIA\ GPU\ Computing\ Toolkit/CUDA/v11.7/include/* nv_sdk
# export PATH="/c/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.32.31326/bin/Hostx86/x86/":$PATH
# export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7/bin/":$PATH
# ./configure --disable-everything --enable-decoder=h264 --enable-decoder=hevc --enable-cross-compile --disable-avdevice --disable-swresample --disable-postproc --disable-avfilter --target-os=mingw32 --enable-cuda-nvcc --enable-nonfree --toolchain=msvc --extra-cflags=-I../nv_sdk --extra-ldflags=" -m32 -L../nv_sdk" --enable-shared --shlibdir=SHARED_LIBS --arch=x86_32 --enable-runtime-cpudetect --enable-w32threads
# make -j8
# make install


first I have a bunch of warnings during the making looking like that :

libavutil/opt.c(1075): warning C4133: 'fonction' : types incompatibles - de 'AVPixelFormat *' à 'int *'

And finally the make install returns :

What am I doing wrong ?
shall I install others packets from pacman ?
