Description concavemail 2019-10-02 22:16:25 UTC 
This error has persisted at least since version 1.14.0. I suspect it has to do with my enabling of the cuda flag. I have attached my build log and will follow with my emerge info.

build.log.tar.gz

Why did you store a single file in a tar archive when you can compress the file itself?
Comment 4 concavemail 2019-10-03 11:11:04 UTC 
No good reason, I just have never used the gzip command before and thought the compression levels would be about the same either way. Thanks for pointing it out, I will use gzip in the futere.

Rebuilding jsoncpp with gcc8 allowed tensorflow to build successfully for me.
Comment 6 Jason Zaman gentoo-dev 2019-12-08 10:37:24 UTC 
its working then? cuda doesnt support gcc9 yet yeah.
