Okay, so I started all over again, installing OSMC using the install GUI, and then updating tp the latest version (May release) using the OSMC update interface. So now my version number is 4.9.29-5-osmc running on raspi 3.
I carefully followed all instructions, checking my history to ensure that I had indeed copy and pasted all commands correctly, and I encountered my first error when trying to make h.256

This seems to be a common bug on raspi 3 builds using gcc 4.9.2, so I modified the Makefiles by replacing every instance of “-mcpu=native” with “-mcpu=cortex-a53”
and “-march=native” with “-march=armv8-a”. That seemed to fixed the make problem and all else went well with building and installing ffmpeg (i.e. successful build with no errors). To be sure that everything was indeed installed, I ran a quick ls /opt/vc/lib and ffmpeg -encoders | grep omx.

I then proceeded to follow the comskip instructions. And once again I had the same error as before

Makefile:423: recipe for target 'comskip' failed
make: *** [comskip] Error 1
In one final attempt of dismay I restarted the whole process all over again, but this time when building the h.256 encoder, I replaced every instance of “-mcpu=native” with “-mcpu=arm1176jzf-s” and “-march=native” with “-march=armv6”. This sets the build to a more general raspi ARM build as opposed to my first attempt which was tailored exactly for the raspi3 architecture. That seemed to fixed the make problem once again and all else went well with building and installing ffmpeg (i.e. successful build with no errors). But to my great dismay, tis more general method still led to the same make error with comskip.
Although I am still a novice with ‘make’, I am fairly competent with linux (my day job is a scientist working exclusively with Cent OS), but I cannot seem to figure out this build process. I am beginning to wonder if anyone else has succesfully followed these instructions on a raspi 3?
Any help or direction is much appreciated.
