v1.9.5 crashes on OS X 10.7

Posted by Jens Alfke on Jul 03, 2011

Sad to report that NodeBox 1.9.5 appears to be unusable on Mac OS X 10.7 "Lion". The app launches and can open files, but as soon as I try to run a script, it crashes:

What terrible news! Is there any chance of a fix to Nodebox 1 to run on OS X 10.7?

I've discovered this too, and I'll look into it next week.

Kind regards,

Any luck with a Lion compatible distribution?

What a bad news, i hope there will be an issue

I know this is an open-source project and your work is likely more focused on the new version of NodeBox, but it would be great if this version could be fixed or some instructions on how to use the http://nodebox.net/code/index.php/Graph">Graph library in NodeBox 2 could be provided. I'm not able to continue work as a result of this bug.

Has anyone tried recompiling the source on 10.7?
(Don't have time to try this morning, but it could be that simple.

Worst case, it's an issue with PyObjC rather than NodeBox.

I have tried to compile...

If you want to get read, this is how you shulod write.

I've created a version for Mac OS X Lion:


Could you test this one and tell me if it works? I'm not sure if it also works on Leopard / Snow Leopard.

There are only minor new features: ellipse() is no an alias for oval(), and there is support for line cap style and line join style.

The source has moved to GitHub:


If you have Xcode (I use 4.1 on Lion) you can build it yourself; it should build without any problems.

Let me know if it works for you!



Posted by Salvatore on Jul 29, 2011

Thank you very much Frederik you are great :-)
It works on OSX Lion



Posted by Barton on Aug 01, 2011

I confirm it works for me too. I was also able to compile on my local machine. Thanks a lot for taking the time to do this.

1.9.7rc1 also crashes for me on Lion (10.7.1), unfortunately. The crash log says:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '/Users/fdb/Dropbox/Projects/nodebox-pyobjc/main.m:36 main() PyRun_SimpleFile failed with file '/Volumes/HardDisk/Code/Others/NodeBox/NodeBox.app/Contents/Resources/macboot.py'. See console for errors.'

The relevant console output is:

9/5/11 12:51:06.019 PM [0x0-0xd80d8].net.nodebox.NodeBox: Traceback (most recent call last):
9/5/11 12:51:06.019 PM [0x0-0xd80d8].net.nodebox.NodeBox: File "macboot.py", line 6, in
9/5/11 12:51:06.019 PM [0x0-0xd80d8].net.nodebox.NodeBox: import objc
9/5/11 12:51:06.019 PM [0x0-0xd80d8].net.nodebox.NodeBox: ImportError: No module named objc

Rather weird — not being able to find the objc module seems like kind of a showstopper and I can't imagine why it's only happening to me. I know Python and I know Objective-C but I've never tried to use them together, so I'm not sure how to troubleshoot this. Any ideas?

Posted by Jens Alfke on Sep 05, 2011

Even weirder, I checked out the nodebox-pyobjc git repository and built the app, and that runs fine.

(Current HEAD is 059b9176, "Graphics view responds to mouse wheel scrolling".)
