Seems like a C++ compilation problem. Can you tell me what version of g++ you have on the machine? Unfortunately the external yocto library I use is using a lot of poorly supported C++ features.

[ptvirgo]

Sure, thanks for looking at it:

I've been trying the release instructions on a series of virtual machines; so far I've tried FreeBSD 12, Debian Jessie, and Ubuntu Trusty64. So far I haven't gotten one to compile. Is there a preferred system / configuration that you recommend for Unix users?

[guillaumechereau]

I usually compile goxel with ubuntu 19.04. There is also a travis build run on an ubuntu 16.04 machine. Both work properly at the moment. As a workaround, can always disable the path tracing rendering compilation with this build command:

scons mode=release yocto=0

[ptvirgo]

That worked. In case anyone else runs into the question, the latest version of Debian also works without additional flags.

Thanks for putting this together and helping me out..!
