A lot of warnings when building FFmpeg in Windows 10

[nothingnew]

I followed what has been told in https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT
Unfortunately, I got a lot of warnings when building the FFmpeg from Windows 10 x64. This is the one of the warning that I got when I run the make command:



I couldn't find Build/Windows10/x64 folder that is supposed to contain all the generated libraries. Please help....
Does it mean the FFmpeg wasn't installed correctly? Please help me...

Would someone please explain the solution?

I have never compiled ffmpeg, but I do have compiled ffmbc, which is a modification of ffmpeg.
And yes, compiling ffmbc successfully does return some tons of warnings.
As long as you get a functional ffmpeg.exe, the warnings can be safely ignored, I presume.

That's the problem, I couldn't seem to find the ffmpeg.exe either. I don't know what's wrong...

"unreferenced local variable" isn't a problem. It's simply telling you that a local variable was declared but never used.

"size_t to int" probably isn't a problem. Look at the code to see if there could be a numeric overflow.

Something tells me "look at the code" is not an option here.

You posted the middle of the output which is not instructive. What are the last couple of lines from each of the configure, make, and make install commands?

I can find the Build/Windows10/x64 folder. But, I can't find the ffmpeg.exe
