Building nheqminer on an Ubuntu 21.10 VM

[Cigydd]

First of all, I should ask if building nheqminer on Ubuntu 21.10 is supported at all. Because I found that the CUDA toolkit is provided for 18.04 and 20.04 only. I installed the 20.04 CUDA into the 21.10 virtual machine and suspect that somebody is doing something nasty here. 😉

Nevertheless, I am going to report my issue just for the case it could reveal a bug.

This is my system information:
bunt-inxi.log

I slightly but minimally modified the build instructions.

• Cloned nheqminer in the ~/software/nheqminer directory.

• Created this script called nheqminer_build.sh in the ~/software directory:

  #!/bin/bash
  
  export LC_ALL=C
  export LANG=C
  export LANGUAGE=C
  cd nheqminer/cpu_xenoncat/asm_linux &&
  chmod +x fasm &&
  sh assemble.sh &&
  cd ../../../
  mkdir -p build && cd build &&
  rm -Rvf * &&
  cmake \
      -DCUDA_CUDART_LIBRARY="/usr/local/cuda-9.2/lib64/libcudart.so" \
      ../nheqminer &&
      # -DUSE_CUDA_DJEZO=0
  make clean &&
  make -j $(nproc)

• Then I ran the command ./nheqminer_build.sh 2>&1 | tee nheqminer_build.log the input of which follows:

  nheqminer_build.log

  The error reads as follows (excerpt from the above log):

  /home/pavel/software/nheqminer/cuda_djezo/../cpu_tromp/blake2/blake2.h:100:21: error: size of array element is not a multiple of its alignment

As you can see, I also played around with disabling the USE_CUDA_DJEZO flag (see the line commented out in the build script). Having that disabled, I ran basically into the same error in the blake2.h file.
