I haven't found a xmrig discussion thread so I'll post here.

Has anyone gotten cuda-plugin to compile on Ubuntu 18.04?
It compiles on 19.04 but 18.04 fails:

Code:

I just asked them about this on reddit, this is their response:

CUDA has very strict compiler requirements, so you have 2 options:

1. Update CUDA to recent version.

2. Install older compiler like
sudo apt install gcc-6 g++-6
and specify compiler on cmake phase
cmake .. -DCMAKE_C_COMPILER=gcc-6 -DCMAKE_CXX_COMPILER=g++-6

install latest cuda: it should use gcc 7
