Build Error on Linux about xmrig-cuda

Try committing more cores with the -jX flag when you do make.

I didn't do this and was stuck on 13% and 25% for a while. It eventually compiled. Making with -j8 made it compiled instantly on my 2700x.

Hhowever, it doesn't work with "Failed to load Cuda Plugin". Still working on figuring that out.

Those warnings are normal. NVCC takes forever if you don't have a lot of memory also and will show nothing ("hang") for up to half an hour in some cases. Linux will swap junk in and out of virtual memory which is super super slow.

Adding more compile threads only works if you've already got way more than enough memory, otherwise it will make it worse.

I am not sure how much memory should I have? Currently, the machine have 4 cores (8 threads) and 16 GB memory.

One thing that helps with compile time is to only enable the CUDA architectures you actually need via the cmake CUDA_ARCH variable. Otherwise it will build for all known GPUs and take forever (I have never compiled without specifying, it could take a while).

The other helpful options are CMAKE_VERBOSE_MAKEFILE and CUDA_VERBOSE_BUILD which should be set ON and then you can actually see what's going on during the otherwise silent long sections. I have never built without these on either, it probably makes the waiting easier.
