py27-matplotlib @1.1.0 Install hangs in setup.py

[macports@…]

During port install py27-matplotlib, the check_for_tk() function in setupext.py hangs on my system when invoked with python and tcl from MacPorts.

This evokes the problem on my machine: port install py27-matplotlib (install hung at "Building" stage -- no CPU usage, no hard drive spinning)

I diagnosed by: cd'ing to the work directory and running setup.py build. It gets as far as the libpng version and then hung. Looking at setup.py, tk is the next test run after libpng. I started a Python 2.7 interpreter and ran import setupext; setupext.check_for_tk(). The process hung.

I can run easy_install matplotlib with system Python and it installs okay. The problem persists after running port selfupdate; port update outdated. I'm running OS X 10.6.8. I've attached a copy of the port install debug log.

This probably deserves to be a Tk bug, but I don't know where to file that and this is how it's manifesting to me. Can you help advise where this belongs?

Thanks!

I can't reproduce this:

The default backend is now the non-interactive Agg backend, different
backends can be specified using the ~/.matplotlib/matplotlibrc file.
More details, regarding backends, can be found in the matplotlib FAQ:

What platform and what version of Xcode are you using?

[macports@…]

Thanks for the response. My versions:

darkside:ninepin tim$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.6.8
BuildVersion:	10K549

darkside:ninepin tim$ xcodebuild -version
Xcode 3.2.6
Component versions: DevToolsCore-1809.0; DevToolsSupport-1806.0
BuildVersion: 10M2518

Building with +cairo -tkinter does not resolve the hang for me, and neither does setting tkagg=False in setup.cfg (which is already set in the -tkinter variant) before running setup.py build manually -- it still tries to check for Tk.

I have a similar problem, except that the installer hangs for me on "Staging py27-matplotlib into destroot". Any thoughts?

My versions are:

Using Lion & XCode 4.2.

After the recent fix that was just made to use llvm-gcc-4.2 (instead of clang 3.0), py27-matlpolib builds but it gets stuck in "Staging py27-matplotlib into destroot"...:

Seems to be the same issue as #30882

I'm leaving the ticket closed in deference to your judgement, but the issue I opened the ticket to report (hang while running matplotlib's setup.py in the build stage) is different from the duplicate issue that other commenters are describing on this ticket (hang while staging into destroot).

[macports@…]

(Though, to be fair, I still think I really have a Tk problem and not a matplotlib problem. I'll try to figure out what the real problem is and refile against Tk.)

They are both apparently hanging when setup.py is called, there is nothing in the logs that explains this; it simply stops. They appear to be the same problem.

Thanks, as I have no idea what's going on here.

[daniel_popescu@…]

could be related to this: 31996?

[daniel_popescu@…]

issue #31996, I mean.

[skymoo (Adam Mercer)]

Seems to be related to the update to Tcl/Tk 5.8.11 which has just happened, so I doubt it.
