I tried to install ffnvcodec for ffmpeg on windows and when I try to install it I get:

make: *** No rule to make target 'install'. Stop.". The command is: "make install PREFIX=/usr

and:

  1. Since I'm still learning, I get that PREFIX=/usr is the directory where I want my program to be installed (correct me if I'm wrong), but I don't know how to specify the location (if you could give me an example it'd be great).

  2. On Nvidia site it says to copy all headers files in a specific directory, which I did, but it gives me this error. I'm new to this, so I don't know what to do and I can't find any solution to this problem.

  • Supposing that the build instructions direct you to run the `make install` command you present, my best guess would be that you are running it from a different directory than the one in which you built the program. – John Bollinger Mar 14 '23 at 19:21
  • Also, if `PREFIX=/usr` does anything in that command, that would be specific to the makefile(s) involved. It has no particular significance to `make` itself. – John Bollinger Mar 14 '23 at 19:23
  • Ahhhhh okay I get it, thank you so much for the answer. Though I feel I'll be back on this site to ask more questions ahah. – Danmrk Mar 14 '23 at 20:05
