I am trying to compile ffmpeg with cuda 11.1 on Windows. I run configure like this:
./configure --arch=x86_64 --target-os=mingw64 --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --enable-gpl --enable-libx264 --extra-cflags='-U__STRICT_ANSI__ ' --extra-cflags=-I../nv_sdk --extra-ldflags=-L../nv_sdk --extra-cflags=-I/usr/local/include/and configure succeeds.
When I run the command make -j 8 I get an error like this:
$ make -j 8CC libavdevice/alldevices.oCC libavdevice/avdevice.oCC libavdevice/dshow.oCC libavdevice/dshow_common.oCC libavdevice/dshow_crossbar.oCC libavdevice/dshow_enummediatypes.oCC
