我正在尝试在 Windows 上使用 cuda 11.1 编译 ffmpeg。我像这样运行 configure：
./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/
并且配置成功。
当我运行该命令时，make -j 8出现如下错误：
$ make -j 8
