error when running make -j $(nproc)

[urmamasllama]

Cmake runs with no errors but make fails with this error ` [ 13%] Building NVCC (Device) object cuda_djezo/CMakeFiles/cuda_djezo.dir/cuda_djezo_generated_equi_miner.cu.o [ 13%] Built target cpu_xenoncat CMake Error at cuda_djezo_generated_equi_miner.cu.o.cmake:207 (message): Error generating /home/llama/build/cuda_djezo/CMakeFiles/cuda_djezo.dir//./cuda_djezo_generated_equi_miner.cu.o

I am seeing same issue

I'm also getting this.

[alabart]

same here. anyone figured out how to solve it?

[aleksandergabriel]

I have same issue (Ubuntu 16.04)

[joseortiz3]

Search issues for keyword "device_functions_decls.h" and there will be at least five issues saying what to do. For me, deleting #include "device_functions_decls.h" from eqcuda.hpp worked. Not sure why its even there.

[alabart]

I did the same and it worked for me: comenting out or deleting the line in eqcuda.hpp //#include "device_functions_decls.h"

[mosh5382]

Thanks joseortiz3, that worked for me on Arch Linux.

[rgaufman]

After deleting #include "device_functions_decls.h from eqcuda.hpp, I'm now getting:

Any ideas?

@rgaufman The error message says you're not using or don't have the right version of gcc

usr/include/crt/host_config.h:121:2: error: #error -- unsupported GNU version! gcc versions later than 6 are not supported! #error -- unsupported GNU version! gcc versions later than 6 are not supported! ^~~~~ CMake Error at cuda_djezo_generated_equi_miner.cu.o.cmake

[rgaufman]

I'm just on a standard Ubuntu 18.04 LTS, I take it there's no support yet?

next steps help me: 1.nano nheqminer/cuda_djezo/eqcuda.hpp delete "device_functions_decls.h" 2.cmake ../nheqminer 3.make -j $(nproc)
