CMAKE Build Failure

[huttered40]

Hi, I am trying to build this library on Stampede2, which is essentially a large-scale cluster of Intel KNL nodes. I follow the provided steps and run into the following error:

login2.stampede2(1127)$ cmake -DCONFLUX_BLAS=MKL -DCONFLUX_SCALAPACK=MKL ..

My cmake version is:

/opt/apps/cmake/3.20.2/bin/cmake

Please advise how to fix this error. Do I need to build COSTA? If so, what additional steps are necessary after doing so? Note that I tried building COSTA, but ran into other issues error: invalid entity for this variable list in omp clause.

Hi, looks like the repo wasn't cloned using --recursive. According to the readme the following should work:

git clone --recursive https://github.com/eth-cscs/conflux && cd conflux

Thanks! I have another issue, (see below), but as its related to COSTA, I'll create an issue in that repository:

Hm, this looks like an issue with the intel compiler. Can you try to comment the two shared statements? I.e.

#pragma omp parallel // shared (..)

Ok, yeah that works for now. I had one other issue (see below), but fixed it myself by adding <int> to the definition of the matrix_view class template. This library builds for me and the cholesky_miniapp works as well. Thanks!
