[Bf-committers] Compile from source

[Post]

Dear Blender,

I am attempting to compile Blender from source using instructions posted 
on 'Dev:Doc/Building Blender/Linux/Generic Distro/CMake'. I was/am 
hoping to establish a dedicated console for running  and testing 
Mechanical Blender even though, as I understand it, it is in a 
pre-release stage. I have a full Blender package, which is fantastic, on 
another system and want to try Mechanical as well.

Following instructions for this procedure as publish all was proceeding 
well until I had a repeated glitch compiling the 'Open-Shading-language'.

Copied from terminal:

This issue may be entirely due to an inadequate operating system, not 
the most powerfull rig in the world nor a particularly good graphics 
card. Operating system MX16 out of Antix out of Debian.
Although, I can and have had Blender running on it quite happily.

Wondering if there is anything to be done other than report and if I 
reload Blender from synaptic will I be able to re-compile it as 
Mechanical in some way?

Many thanks

Steve
