Python installation issue #2

Closed dttrugman closed 5 years ago

dttrugman commented 5 years ago

Hi, I'm trying to install the python version on Mac (or Linux - neither has worked for me).

I keep getting a strange error message: Failed building wheel for okada-wrapper Command "/anaconda3/bin/python -u -c "import setuptools, tokenize;file='/private/var/folders/xp/b5yg9w6j1qnfhzw22xd_p01m0000gn/T/pip-install-n9outi2d/okada-wrapper/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /private/var/folders/xp/b5yg9w6j1qnfhzw22xd_p01m0000gn/T/pip-record-tv__isgf/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/xp/b5yg9w6j1qnfhzw22xd_p01m0000gn/T/pip-install-n9outi2d/okada-wrapper/

I'm running Python 3.6.7. Any tips/suggestions? I've attached the full terminal output in case that helps. error.txt

The main error is the linker error I copied from below. It looks like the issue is that there's some failure in linking to the Python system libraries. okada_wrapper uses a numpy package called f2py to wrap the Fortran code and make it callable from Python. Could you try to use f2py to wrap some simple Fortran code and see if you get the same error? This is a useful guide: https://docs.scipy.org/doc/numpy/f2py/getting-started.html#the-quick-way If you do get the same error with simpler Fortran code, you might get better advice by contacting the f2py folks for help. The other thing I see in the error log is ld: warning: directory not found for option '-L/lib'. That might be part of the issue with your python library path.

Thanks. Using basic f2py gives a very similar error. You may be right about the warning. The strange thing is that there is no /lib on my computer, so I wonder why it is trying to link to it?

Huh. Good luck figuring this out! I don't think I'm going to be very useful.

Hello, Was this issue ever resolved? I am getting a similar error message with python setup.py install. Please let me know. I am happy to help troubleshoot. Rob

tbenthompson commented 4 years ago

This was never an issue with okada_wrapper but instead an issue with his f2py installation. You may be having similar problems.
