Invalid Mex-file error #186

Open srvanrell opened 9 years ago

Hi there,

Running a simple script (just to test pymatbridge installation) I get an error that I don't understand.

This is the script:

#!/usr/bin/python 
from pymatbridge import Matlab

mlab = Matlab()
mlab.start()
print "Matlab started?", mlab.started
print "Matlab is connected?", mlab.is_connected()
mlab.run_code("count10 = 1:10")
mlab.run_code("magic_matrix = magic(5)")
mlab.stop()

... and this is the log:

Starting MATLAB on ZMQ socket ipc:///tmp/pymatbridge
Send 'exit' command to kill the server

what could be happening? or what could I do?

How did you install the bridge?

What OS are you using? Python version?

It wasn't installed for myself. I have passed the instructions to the administrator of the cluster. pymatbridge was installed using pip, assuming he followed my instructions.

That machine has Debian (uname description: Linux neptuno 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u1 x86_64) and Python 2.7.3.

Thanks for reporting back. I think that this should be fixed in the upcoming (long overdue...) release. This will take a couple of weeks though. Sorry for the delay!

OK - just released a new version of this, which hopefully solves this issue. Could you please give it another try and report back?

srvanrell commented 9 years ago

I'll give it a try and will report back as soon as possible.

I tried the same test script as above and I get the error attached here. HTH.

What version of pymatbridge are you using? What happens when you type the following? 

import pymatbridge
pymatbridge.__version__

Sigh. I was hoping we would get over that with this version. Let me think about this.
