Getting an error attempting to use Monogame on Debian Linux

I’ve got Monogame working mostly, just that when I try to compile anything that uses Monogame.Framework.Linux I get a bunch of build errors.

Here is my build log:

Any other information you guys might need?

I have few questions:

How did you install monogame?
did you try to build it from source?
did you install the extension?
which extension did you use?

I’m so sorry this is such a late reply. I kinda gave up

But I’ve got it to work, now. I’m not sure how I got it, but I just downloaded from the github and compiled and added OpenTK and it worked.
