Hello everyone,
I’ve been trying to compile Blender 2.78 on the Raspberry Pi 3B. Because I wanted to be able to render (the raspberry pi is very usable for a renderfarm) and to open the gui, (an opengl driver has been in development for some time).
I came across various problems that could be solved like: no sse and missing libraries, but now I came to compiling Open shading Language, I’m stuck. It gives an error about some integer that it tries to convert to some weird thing. It was compiling through cmake and with GNU CC 4.9.2 (both C and C++) and i got the following output:

ERROR! OpenShadingLanguage-1.7.3 failed to compile, exiting
I had to cut some succesfully compiled things away, otherwise it would be too long.
I’m new to C, but it’s hard to believe that there is an error in the code of OpenShadingLanguage.
I tried it with boost 1.60 (self-compiled) and 1.62 (self-compiled), tried compiling LLVM myself and with OSL 1.7.3 and 1.7.4, but none of this gave a different output.
I wish somebody could help me, because I’m completely lost:confused:.
Greetings, Animajosser
