Fail to start on RHEL (using the Canopy python distribution)

Hi,

I’ve installed pymatbridge, while using the Canopy python distribution. I followed the instructions on how to install pip packages on canopy (from here: https://support.enthought.com/hc/en-us/articles/204469690-Installing-packages-into-Canopy-User-Python-from-the-OS-command-line).

Then, running the following on the ipython notebook, fails to start:

from pymatbridge import Matlab
mlab = Matlab() # I also tried writing the explicit path/matlab 

mlab.start()

and results with:

Starting MATLAB on ZMQ socket ipc:///tmp/pymatbridge-65d47756-5dfc-4664-a666-233d18c23393
Send 'exit' command to kill the server
............................................................MATLAB session timed out after 60 seconds

ValueError: MATLAB failed to start

EDIT: Looking on the terminal console. Looks like ipython generates the following errors:

Invalid MEX-file
'~/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/pymatbridge/matlab/messenger.mexa64':

~/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/pymatbridge/matlab/messenger.mexa64)

Thanks a lot for your assistance!

Okay, I see. It’s the matlab stdc++ library (in matlab/R2014b/sys/os/glnxa64) that is missing GLIBCXX_3.4.20

[raylim]

Yes, not sure why it’s picking up that libstdc++.
