Hi Hans-Ekkehard,

Here is some info on my mpicxx installations (after a brew uninstall and brew install):

staude:bld staude$ which mpicxx
/usr/local/bin/mpicxx
staude:bld staude$ ls -la /usr/local/bin/mpicxx
lrwxr-xr-x  1 staude  admin  35 Oct 28 08:42 /usr/local/bin/mpicxx -> ../Cellar/open-mpi/4.0.2/bin/mpicxx
staude:bld staude$ mpicxx --version
Apple LLVM version 9.0.0 (clang-900.0.38)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Does that help?

Best,
Benjamin

Hi Benjamin,

It is curious that MPI is not found on your system. Could you double check that you have installed open-mpi via Homebrew? What does

which mpicxx

return on your system?

Best,
Hans Ekkehard

Hi Hans-Ekkehard,

Thanks for the support, that solved one issue. But now, I get the same for OPEN_MPI:

-- Could NOT find MPI_C (missing: MPI_C_WORKS) 
-- Could NOT find MPI_CXX (missing: MPI_CXX_WORKS) 
-- Could NOT find MPI (missing: MPI_C_FOUND MPI_CXX_FOUND) 

(I need open_mpi because I need the MUSIC interface). This is my cmake-call:

cmake \
-DCMAKE_C_COMPILER=gcc-9 \
-DCMAKE_CXX_COMPILER=g++-9 \
-Dwith-music=ON \
-Dwith-mpi=ON \
-Dwith-openmp=ON \
-DCMAKE_INSTALL_PREFIX=/Users/staude/.pyenv/versions/3.7.2/ \
/Users/staude/Projekte/RainerDunkel/SensoryNetwork/Skripte/snn/NEST/nest-simulator-2.18.0

Hi Benjamin,

The CMake output shows that you are using the AppleClang compiler, which does not support OpenMP. If you want to use that compiler, you need to turn off OpenMP with -Dwith-openmp=OFF.

If you want NEST with OpenMP on the Mac, I would recommend using the GCC compiler installed via Homebrew, see

https://nest-simulator.readthedocs.io/en/latest/installation/mac_install.html

for instructions.

Best,
Hans Ekkehard

Hi there,

I am trying to install nest under OSX Mojave and run into the following cmake-error (see below for a full trace):


-- Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES) 
-- Could NOT find OpenMP_CXX (missing: OpenMP_CXX_FLAGS OpenMP_CXX_LIB_NAMES) 
-- Could NOT find OpenMP (missing: OpenMP_C_FOUND OpenMP_CXX_FOUND) 

I already tried various tricks (http://stechschulte.net/2016/03/20/openmp-osx-cmake.html, https://stackoverflow.com/questions/48825416/missing-openmp-c-flags-openmp-c-lib-names), but had no success. Does anybody have experience?

Thanks in advance,
Benjamin
