Compile error #39

PatWalters commented 6 years ago

This package looks great, but I can't build it. I'm getting this error when building on Ubuntu 14.04.5 with cuda 8. Any help would be greatly appreciated. Thanks.

Hi! What's your gcc version?

PatWalters commented 6 years ago

gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

vmarkovtsev commented 6 years ago

Right, 4.8 is too old. However, you can safely comment out those pragmas, it will still work correctly.

PatWalters commented 6 years ago

Thanks, I'll upgrade my gcc and give it a try

Assuming as fixed, please reopen if there is still an issue.
