py27-wxpython: NameError: global name 'log' is not defined

[cdeil (Christoph Deil)]

After upgrading from XCode 4.3 to 4.4 on my Lion Macbook, I got the following error:

$ python -c 'import wx'

So I tried to uninstall and reinstall

sudo port uninstall py27-wxpython
sudo port uninstall wxWidgets
sudo port install py27-wxpython

but now the py27-wxpython install fails with a

NameError: global name 'log' is not defined

The full log is attached.

The wxpython software is only available in a 32-bit version. You must therefore run python in 32-bit mode if you want to use wxpython.

$ arch -i386 python -c 'import wx'

but now the py27-wxpython install fails with a

NameError: global name 'log' is not defined

Yes it had problems locating the "log" function for some reason, but more importantly, what it was trying to use the log function to display was the message "Compiling with an SDK that doesn't seem to exist". The SDKs are in a different location in Xcode 4.3 and 4.4 than in earlier versions and the port might need an update to accommodate that.

[macports@…]

Can you clarify the last response? I have this error as well: what actions do I need to take to work around it? What does it mean that the port "might" need an update?

[jmroot (Joshua Root)]

wx uses long-deprecated APIs that were finally removed from the headers in 10.7. It thus can only be built on 10.7+ by using the 10.6 SDK. Xcode 4.4 does not have a 10.6 SDK. The only real fix to this mess is for upstream to release a new stable version that doesn't use the removed APIs.

Cf. #35372

I am also having this same problem but I am on Leopard, 10.5.8, and I am trying to re-install. Same messages.

The same problem here, same OS (MacOSX, 10.5.8), Xcode 3.1.4 so it seems not to be related only to Xcode 4.4 update. I'll attach a full main.log from a 10.5.8 system.

By the way: py26-wxpython subport builds fine on the same system! I know, it has quite different dependencies. Let me know if you are interested in an mail.log from this build as well.

Are you still able to reproduce the error?

This actually seems like two unrelated errors here. The one on 10.5 tries to use:

log.warn("Compiling with an SDK that doesn't seem to exist: %s",

and I suspect that wxPython might be smart for you with something like

cflags.append("/Developer/SDKs/MacOSX10.3.9.sdk")

but on the other hand it might indeed be a problem that "log" doesn't exist.

I think I removed setting any SDK on anything else but Lion, but it would be helpful if those experiencing the problem could try to test again with the new port py27-wxpython-2.8 +carbon (or +gtk for that matter).

[mojca (Mojca Miklavec)]

I reported the bug upstream: ​http://trac.wxwidgets.org/ticket/15462

Unless I'm mistaken, hitting this error means that there is probably a problem on your OS anyway (like SDK which disappeared - even though wxWidgets should still work in that case), but it still seems like a bug that is still present in the wxPyton 2.9.4.0. Since nobody reported it for 2.9.4, I'll simply wait for the upstream to fix the bug, while I will blindly try to fix 2.8.12.1 by importing the log module.

[mojca (Mojca Miklavec)]

Untested commit r110469 (probably not sufficient for upstream though). Please report back if there are still problems. There are a number of places where log.warn is also used in wxPython sources and I didn't attempt to fix those. I hope these problems will be fixed upstream.

[cdeil (Christoph Deil)]

I just wanted to confirm that the issue is solved for me on Mac OS X 10.7 and 10.8. @mojca Thank you for your work!
