cannot open libzmq.so.3

[raul678]

I use python from anaconda through tcsh.

After mlab.start(), I met this error.

'''
Invalid MEX-file
'/chimerahomes/jingtao/anaconda/lib/python2.7/site-packages/pymatbridge/matlab/messenger.mexa64':
libzmq.so.3: cannot open shared object file: No such file or directory

Error in matlabserver (line 7)
messenger('init', socket_address);
'''

I found the location of libzmq.so.3 is /chimerahomes/jingtao/anaconda/lib. And I add this to DYLD_LIBRARY_PATH in .cshrc file.
'''
setenv LD_LIBRARY_PATH /opt/stow/cuda/cuda-5.0.35/lib64
setenv DYLD_LIBRARY_PATH /chimerahomes/jingtao/anaconda/lib
'''

Also I installed pyzmq via 'conda install pyzmq'.

How can I fix it?
Thanks :)

Hi - are you installing pymatbridge from the current master or from a released version?

[raul678]

Hi I use "pip install pymatbridge"..

[arokem]

I think that the recent changes on the master branch of the repo might help you. Would you mind trying to download the code from the repo and installing using python setup.py install?

I have the same issue on Ubuntu 14.04 with Python 3.4. My whole project is in a virtual environment, so I installed pyzmq in it, and then pymatbridge. Both using pip.

Hi - could you try installing from source instead? It should solve this
problem. We should put out another release soon...

Alright, so I followed the instructions on the README to do so. These are not exactly correct ; the following commands :

python make.py
...
python setup.py

Must be replaced with :

python make.py matlab
...
python setup.py install

And python make.py matlab gave an error (Not a directory). But the setup worked.
I also had to install numpy.

Anyway, at the end it worked, I could execute some Matlab code and get the result. Even in the virtual environement (just need to activate it before running python setup.py install).
I'm still waiting for a more convenient package though 😉

Is this what you meant? #181

[kjaquier]

Yes, well, I guess its also python setup.py installfor Octave.
Also, it's written in the introduction that Numpy is only necessary for the Matlab magic extension, which apparently is not case.

Thanks for the feedback - I updated the PR accordingly.
