Compile on Mac generates error but generates dylib anyway in invisible .libs folder about vapoursynth-colorbars HOT 2 OPEN

That's a silly warning, not an error.

Pretty sure it's expect behavior for autotools to put its output in .libs. The same thing happens on Windows at least. All the cool kids are switching to meson, so maybe I'll try that some time.

As in the README, you can just compile it yourself with gcc. It'll need a little tweaking for OSX, though:

gcc -c colorbars.c -I include/vapoursynth -O3 -ffast-math -mfpmath=sse -msse2 -march=native -std=c99 -Wall
gcc -shared -o colorbars.dll colorbars.o -Wl,--out-implib,colorbars.a

If you figure out a one or two-liner for OSX, I'll document it.

For OSX

• Install homebrew: https://brew.sh
• Install dependencies via command line:
  • brew install VapourSynth
  • brew install autoconf
  • brew install libtool
• run instructions for "autotools" compile of VapourSynth-colorbars and ignore generated error message
• move libcolorbars.dylib to VapourSynth default plug-ins folder or define it as per instructions @ http://www.vapoursynth.com/doc/autoloading.html

Optional (this will allow you to export different video formats thru pipe)
