[gradsusr] [EXTERNAL] GrADS 2.2.1 on macOS Catalina

What is your $LD_LIBRARY_PATH? Where is your libgradspy.dylib?

Hi Jennifer,

Thank you very much for your reply and instructions. The same error still shows up. I have set up PYTHONPATH, which was empty, and re-run setup.py, I got this:

>>> python setup.py install
running install
running build
running build_ext
running install_lib
running install_egg_info
Removing /Library/Python/2.7/site-packages/gradspy-1.0-py2.7.egg-info
Writing /Library/Python/2.7/site-packages/gradspy-1.0-py2.7.egg-info
>>>

The command 'echo $PYTHONPATH' gives this:

>>> echo $PYTHONPATH
/usr/bin/:/Library/Python/2.7/site-packages/:/Library/Frameworks/Houdini.framework/Versions/15.5.523/Resources/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

>>> ls -1 /Library/Python/2.7/site-packages/
Extras.pth*
README
gradspy-1.0-py2.7.egg-info
gradspy.so*
It seems python is still not linked to grads for some reason. I am not sure what is missing.

Thanks,
Mukesh

Hi, Mukesh –

Your LD_LIBRARY_PATH variable (~$HOME/grads-2.2.1/lib) might not be correct; try removing that leading ~
As a check, run `echo $LD_LIBRARY_PATH` and make sure that your libgradspy.dylib exists in the directory (or directories) listed.

You may also need to set the PYTHONPATH environment variable. On my mac it looks like this:

> echo $PYTHONPATH

/Users/jmadams1/anaconda3/lib/python3.7/site-packages:/Users/jmadams1/bin

> ls -1 /Users/jmadams1/anaconda3/lib/python3.7/site-packages/*gradspy*

/Users/jmadams1/anaconda3/lib/python3.7/site-packages/gradspy-1.0-py3.7.egg-info

/Users/jmadams1/anaconda3/lib/python3.7/site-packages/gradspy-1.1-py3.7.egg-info

/Users/jmadams1/anaconda3/lib/python3.7/site-packages/gradspy.cpython-37m-darwin.so*

Note: I see the documentation says, “We haven't done any testing with Python 3.” Actually, I do have a python3 version of gradspy and some new features  that make it easier to pass data back and forth between GrADS and Python. I just haven’t been able to find any spare time to put it all together into a new release.

Hello,

I am writing to seek some help for the installation of GrADS 2.2.1 on macOS Catalina. I have successfully followed instructions (http://cola.gmu.edu/grads/gadoc/python.html<https://urldefense.proofpoint.com/v2/url?u=http-3A__cola.gmu.edu_grads_gadoc_python.html&d=DwMFaQ&c=ApwzowJNAKKw3xye91w7BE1XMRKi2LN9kiMk5Csz9Zk&r=M2mFZsxo0ZoztoK2Lyoypu1kKkBVKyEoM9CXGWO42zk&m=PtLkxnFdiXoIxQ-WaidMJIDPbVoUc97GKk5mxLuDcuE&s=6nss2yW7vVvCOgOpKTC_wCxwYpghNuXGc_2AgK1Nbfs&e=>) and ran 'python setup.py install' on Python 2.7; however, the last step did not work.

The environment variable 'LD_LIBRARY_PATH' path was updated to ~$HOME/grads-2.2.1/lib. Writing 'import gradspy' on python prompt gives this error:

>>> import gradspy
dlopen(libgradspy.dylib, 9): no suitable image found.  Did find:
    file system relative paths not allowed in hardened programs
>>>

The file 'libgradspy.dylib' exists in the ~$HOME/grads-2.2.1/lib and the build directory was created after running setup.py.

Does anyone have any recommendations or solutions to what is causing this error?

Many thanks in advance.

Regards,

Mukesh
