[gradsusr] [EXTERNAL] GrADS 2.2.1 on macOS Catalina

Wed May 20 08:55:16 EDT 2020

Can you run GrADS outside of python?
Try googling the error message, “file system relative paths not allowed in hardened programs” and see if you can figure out what that means in your case.

Hi. Here is the LD_LIBRARY_PATH:

>>> echo $LD_LIBRARY_PATH
/Users/mukeshgupta/grads-2.2.1/lib

The location of 'libgradspy.dylib' is here:

>>> pwd
/Users/mukeshgupta/grads-2.2.1/lib
>>> ls -1 libgrads*
libgradspy.0.dylib*
libgradspy.dylib@
libgradspy.la*
>>>

Note that 'libgradspy.dylib@' is a link to 'libgradspy.0.dylib'. That's all.

Thanks,
Mukesh

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
