NuPIC on Ubuntu 16.04 LTS


the new LTS version of the popular Linux OS is available and I’m considering migration; wanted to ask if anybody is successfully running Nupic (and nupic.core) on this version?

Are we still stuck with gcc-4.8 compiler for some reason? (And no limits on clang?)

The LTS upgrade will be available in June, will we consider upgrading the Travis envs at some point too?

I had problems compiling on Ubuntu 15.10, which you can see here. You can find even more details by searching for Ubuntu 15 on our search page.

I have not tried on 16 yet.

Unfortunately, we don’t have control over the Travis-CI environment. We’ll get upgraded when they upgrade. :rolling_eyes:

Thanks @rhyolight, I’ll test it in a VM tonight and spawn new issues along the way :stuck_out_tongue:

Created PR #984 for gcc 4.9 (and higher) compatibility (gcc >= 4.9 requires gcc’s own wrappers for some binutils (ar, ranlib)). Works fine on Ubuntu 15.10 with gcc 4.9.x. The proposed fix might also work with Ubuntu 16.04.

Just tested PR #984 on Ubuntu 16.04 LTS with gcc 5.3.1; build and tests (unit-tests, cpp-region) successful.
