Error while "make -j $(nproc)" because of CUDA9 and GCC6

[tunnckoCore]

Seems like CUDA requires GCC6 but errors with it :D Pretty fantastic logic...

I know it's not a problem here, but some thread or workaround about that?

ArchLinux user here. Let me know if more info is needed.

Same :/

@olstenlarck @andersfylling I just built this on Arch using CUDA9 and GCC6. Not officially supported but it seems to work for me.

pacman -S cuda
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/cuda/lib64"
export PATH="$PATH:/opt/cuda/bin"
export CXX="/usr/bin/g++-6"
export CC="/usr/bin/gcc-6"

Open nheqminer/cuda_djezo/eqcuda.hpp in your favorite text editor and remove the line that's including the device_functions_decls.h header then save the file. Now follow the linux instructions in the README.md document.

@CtrlC-Root Thank you so much, this works for me as well !
