crash and python location

Posted by todd on Feb 12, 2007

Hi,
When first starting nodebox i received an error that it could not find the python runtime and to change this in the Info.plist.

I did this as I only have the 2.4 Framework version installed which now lives in
/Library/Frameworks/Python.framework/Versions/2.4/Python

Now it crashes on startup. Below is the crash report. Do I need to have 2.3 installed? I did not see that as a requirement.

NodeBox is compiled using the --semi-standalone flag, which means it expects a Python to be already installed. Normally, this is no problem, since on Mac OS X 10.4, Python 2.3.5 is installed by default in /System/Library/Frameworks/Python/Version/2.3/.

It's kind of strange that the default Python wouldn't work. It could be that you permissions are set wrong. Can you run python2.3 from the Terminal?

Kind regards,

Frederik

Actually I do not have 2.3 on my system as I removed it. I replace it with 2.4. I will fix this and see if it works.


Posted by todd on Feb 13, 2007

ok. it is all fixed now. sorry for the confusion.


Posted by Chris on Feb 14, 2007

Hi, I thought that it was in:
/System/Library/Frameworks/Python.framework/Version/2.3/

Mine is there and I get the same crash....


Posted by Frederik De Bleser on Feb 14, 2007

Is there something in the Console window (/Applications/Utilities/Console)? Clear it out, then run NodeBox to see if anythin appears there. Otherwise, could you mail me the crash log? My e-mail address if frederik at the domain name pandora.be

I found out that the problem (again) is input managers. You might want to read a previous form post on this.

I had removed python2.3 from my system, so I reinstalled it using an old macpython installer. It went in /Library/Frameworks/... instead of /System/Library/Frameworks/..

This seems to work fine for most of nodebox, but when I tried using the Graph library, I get an error

Hi Neal,

You might want to try building boost from the source. I included instructions on our developers wiki: http://dev.nodebox.net/wiki/BuildingBoost

Kind regards,

Frederik

Hi, thanks. It turns out it was a problem with the python installation, in particular with the permissions. By copying an existing python 2.3.5 framework from another mac, and being careful to get the permissions exactly right, I fixed the problem.
