Well.... install make (nvidia's instructions include that).

What's your intended build environment? VisualStudio of msys2/mingw? If mingw, did you install the 'c' compiler?

The nvidia instructions don't cover installing a heap of things, like the compiler and a lot of packages. (They also say "–-toolchain=msvc" even as they're giving instructions for mingw, which is suspect (I haven't looked at the code yet to see if it matters.)

So first, make sure you have a working build environment, that's out the scope of this list. Then look at the instructions for building ffmpeg-

I use "Option 2: MSYS2" of
https://trac.ffmpeg.org/wiki/CompilationGuide/MinGW

If you're using visual studio, see
https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC

You'll have to manually install any needed packages, usually ./configure will tell you when something's missing.

Once you can build ffmpeg without cuda, then try building with cuda. And you may want to follow up with nvidia if you're using their instructions.

Later,

z!
