CMake error. Could NOT find Threads (missing: Threads_FOUND)

[Fabio Affinito]

Dear all,

I'm trying to install QMCPack on D.A.V.I.D.E. cluster (http://www.hpc.cineca.it/content/davide), which is a Power8 + Tesla P100 system. For my build I'm using GNU 6.4.0 compilers and CUDA toolkit 9.2.88.

When I try to run the cmake:

 faffinit@davidefe02 davide-bld-gpu]$ cmake -DCMAKE_C_COMPILER="mpicc"  -DCMAKE_CXX_COMPILER="mpiCC" -DQMC_CUDA=1 -DLAPACK_LIBRARIES="/cineca/prod/opt/libraries/lapack/3.8.0/gnu--6.4.0" -DBLAS_LIBRARIES=$BLAS_HOME -DLIBXML2_LIBRARY="/davide/home/userinternal/faffinit/libxml2-2.9.8/lib/lib" -DLIBXML2_INCLUDE_DIR="/davide/home/userinternal/faffinit/libxml2-2.9.8/lib/include/"  ..

it fails with this "Could NOT find Threads (missing: Threads_FOUND)" error (see the error stack at the end of the message).

Do you have any hint?

Thank you in advance,

Fabio

Ciao Fabio,

QMCPACK was built successfully on Minsky platform in the past. So we should be able to make it working without much effort.

The error message tells us that the threading library cannot be located. I actually never hit this issue in my 4-year experience with QMCPACK.

On linux machines, pthread is always available. So it never failed for me.

FindCUDA.cmake error is also requiring a thread library.

Another potential issue is due to the -march=native flag which is not valid for powerpc. This has been fixed in v3.5.0 release. So please try the most recent released version of QMCPACK.

Best,

Ye

Hi Ye! 

Thanks for your suggestion. Moving to 3.5.0 release fixed the problem!

Best,

Fabio
