Builds fine for me with gcc-6.3.0

[Comment 2 Oleg Korsak 2017-03-22 21:07:42 UTC]

how is that possible? please show gcc -v

[Comment 3 Andreas Sturmlechner 2017-03-22 22:09:28 UTC]

Works for me as well. Of course this problem is brought to you by the green graphics mafia.

Sorry.  Forgot USE="cuda".  I'll try again.

I still have no trouble emerging it.


gcc -v is:

[Comment 6 Andreas Sturmlechner 2017-03-22 23:34:33 UTC]

The message is coming from cuda.eclass, and its content depends on the result of cuda-config from dev-util/nvidia-cuda-toolkit.

Closing, as there is nothing to be done here.
