Hello Hans,
Thank you for a detailed description of your setup and steps.
I checked them with mine and although I do not have all the brew packages that you have in
your complete list, I have the ones you mentioned in brew leaves.
I tried to install nest with Apple’s Clang with the option -Dwith-mpi=OFF. I got the below
errors during cmake.
-- 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)
CMake Error at cmake/ProcessOptions.cmake:466 (message):
CMake can not find OpenMP.
Call Stack (most recent call first):
CMakeLists.txt:146 (nest_process_with_openmp)
I saw another
thread<https://www.nest-simulator.org/mailinglist/hyperkitty/list/users@…
with the same issue and found that I had open-mpi installed via homebrew as mentioned
there. The thread also mentions libomp package. I installed that and the errors were gone.
The make install command was successful. After this, when I imported nest into python, I
got the below errors
OMP: Error #15: Initializing libomp.dylib, but found libiomp5.dylib already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the
program. That is dangerous, since it can degrade performance or cause incorrect results.
The best thing to do is to ensure that only a single OpenMP runtime is linked into the
process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an
unsafe, unsupported, undocumented workaround you can set the environment variable
KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause
crashes or silently produce incorrect results. For more information, please see
http://openmp.llvm.org/
Abort trap: 6
I did the workaround as suggested in the message by setting KMP_DUPLICATE_LIB_OK=TRUE.
This setting indeed got rid of the above error and the import was successful, but as
mentioned, the behaviour could be unpredictable.
I couldn’t find any other way to work around the initial OpenMP_C and OpenMP_CXX errors
other than installing libomp package. Do you know if there is any other way to resolve
that error?
Thanks,
Pooja

Hello everyone,
I have a Mac with Big Sur and I tried installing NEST with a Conda environment as
mentioned
here<https://www.nest-initiative.org/mailinglist/hyperkitty/list/users@n…
by pulling in the latest code from Github. My commands look like this
conda create -n nestml_dev nomkl numpy scipy matplotlib ipython cython nose pytest
conda activate nestml_dev
<Pull the latest code from github>
mkdir nest-simulator-build
cd nest-simulator-build
cmake -DCMAKE_INSTALL_PREFIX:PATH=<nest_path> -DCMAKE_C_COMPILER=gcc-10
-DCMAKE_CXX_COMPILER=g++-10 <nest_src>
make -j4
make install
After this, if I try to import nest in python or run nest from the command line, I get the
following error
OMP: Error #13: Assertion failure at kmp_csupport.cpp(590).
OMP: Hint Please submit a bug report with this message, compile and run commands used, and
machine configuration info including native compiler and operating system versions. Faster
response will be obtained by including all program sources. For information on submitting
this issue, please see http://www.intel.com/software/products/support/.
Abort trap: 6
Has anyone else seen this error? Any pointers on this would be helpful.
Thank you,
Pooja
