Issue: Build Fails on Gentoo with CUDA 9.1, GCC 6.4, Python 3.5
Labels: module: build,triaged

Hello,
I have been unable to compile the source on my gentoo box.  Here are the error messages I'm currently getting:

and then several more pages of this.  Any ideas?  Please let me know if there's particular information that I'm omitting that would be helpful.
