[ili3p]

It's not due to Cuda 7.5, it fails with 7.0 too with the same error

[ili3p]

I tried wth C and CXX 4.8.2 still the same problem. On one server it succeeds but I cannot figure out why..

[ili3p]

OK I think I figured it out why it works on one server. That server has an older installation of torch. So, spectral-lib cannot be installed with the latest version of torch.

[ili3p]

Ok the problem was the Lua version, it only works with 5.1 not 5.2!
