Enthought Canopy and Micro-Magager

Question

I'm trying to use the Micro-Manager wrapper for python (https://micro-manager.org/wiki/Using_the_Micro-Manager_python_library) with Canopy. When I run the simplest demo program:

from MMCorePy import *
mmc = MMCorePy.CMMCore()

#  Load and initialize the demo camera device:
mmc.loadDevice("cam","DemoCamera","DCam")
mmc.initializeDevice("cam")

# Snap and retrieve an image:
mmc.snapImage()
im1 = mmc.getImage()

# Display the image:
from pylab import *
ion() # Activate interactive mode
figure()
imshow(im1,cmap = cm.gray)

I get and error that i can't repair:

ImportError: dlopen(./_MMCorePy.so, 2): Symbol not found: __ZTI8CMMError
Referenced from: /Applications/Micro-Manager1.4/_MMCorePy.so
Expected in: flat namespace in /Applications/Micro-Manager1.4/_MMCorePy.so

I've tried to change the working directory to the folder where all the files are, as well as I tried to copy all the needed files in a new folder and use that one as a working directory. All the times, the same error. I just can't make it work! p.s. The program I posted is just the demo given by Micro-Manager itself. Thanks for any suggestion!

Short answer: install new stable Micro-Manager version, because yours wasn't built properly.

Near 25th Jan 2014 I was trying to build MM for Archlinux and had same issue as you with incomplete setup.py build script. There is missing zlib, boost and unlinked binaries. This diff fixes issue.

At now I see, MM devs totally switched from native python build system to Make. Seems to be, 1.4.17 version and newer was built without issue.
