I 'm fighting 3 days now to setup my venv... I need cython, openmp.... My IDE is PyCharm Prof in macOS... I have tried plenty solutions with no result...
when i try to build with PyCharm... the building result is:
UserWarning: Unknown distribution option: 'cmd_class' warnings.warn(msg)
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: no commands supplied
so, when i try with:
python setup.py install build_ext --inplace
No build again.... The error is following:
ld: warning: directory not found for option '-L/install/prefix/lib'
ld: warning: -L path '/usr/local/Cellar/llvm/9.0.1/lib/libomp.dylib' is not a directory
ld: warning: directory not found for option '-L/install/prefix/lib'
ld: warning: directory not found for option '-L/usr/local/Cellar/gcc/9/gcc/x86_64-apple-darwin19/9.3.0/include/omp.h'
ld: library not found for -lomp
clang-9: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/local/opt/llvm/bin/clang++' failed with exit status 1
i have already install:
brew install llvmbrew install libomp
clang version 9.0.1
Target: x86_64-apple-darwin19.3.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin
The setup.py is according to https://cython.readthedocs.io/en/latest/src/userguide/parallelism.html but i have try a lot of differents mods... i am trying to setup 3-days now...
Finally... i know that the compilation is completed with errors. Although if i try to run it... i have the following resutlts... maybe it helps...
ImportError: dlopen(myfile.pyx, 2): Symbol not found: _omp_get_num_threads
Referenced from: myfile.pyx
Expected in: flat namespace
in myfile.pyx.cpython-36m-darwin.so
I 've read somewhere that there is no way to implement in OSX Cython-App with usage of openMP but i m still believe that there is a way... My system is macOS Catalina 10.15.3 ... I need your help!!!
