I’m struggling with the ‘pip install’ approach to getting pysteps installed on my Mac (OS Mojave 10.14.2). I’ve tried:
pip install numpy
(which was successful)
pip install git+https://github.com/pySTEPS/pysteps
after progressing some way, it fails with the following message:
:
:
creating build/temp.macosx-10.9-x86_64-3.7/pysteps/motion
gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -arch x86_64 -g -I/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/numpy/core/include -I/Library/Frameworks/Python.framework/Versions/3.7/include/python3.7m -c pysteps/motion/_vet.c -o build/temp.macosx-10.9-x86_64-3.7/pysteps/motion/_vet.o -fopenmp
clang: error: unsupported option ‘-fopenmp’
error: command ‘gcc’ failed with exit status 1
Any thoughts as to why this fails?
The text was updated successfully, but these errors were encountered:
Hi Luigi, as @pulkkins said, it seems that the macOS the default compiler (clang LLVM) does not support openmp yet.
One possible solution is to use Anaconda to create the Pysteps environment and install the following packages:
conda install llvm gcc libgcc And then install Pysteps in that environment.
Another option is to update the compilers:
xcode-select --install export CC=clang ; export CXX=clang pip install git+https://github.com/pySTEPS/pysteps Thanks! I’ll give it a try and confirm success one way or another. Regards!
Reference to this Another option is to update compilers
For me the above command didn’t work but this one worked.
export CC=/usr/local/Cellar/gcc/8.2.0/bin/gcc-8
Hi @m-anand, thanks for the other solution. Did you update the compilers using homebrew? Can you share the commands that you used so they can be used as reference?
Thanks!

I used :
brew install gcc
export CC=/usr/local/Cellar/gcc/8.2.0/bin/gcc-8
I’ve update gcc using brew as suggested by @m-anand but it didnt work. I get slightly further than last time, but invariably:
