Re: Temperature calibration & re lax @ Mac OS X 10.7.3 „Lion“ -- April 04, 2012 - 18:59

Hi Edward,

I am seeing the same issues reported by others.

 $ open /programs/i386-mac/relax/1.3.14/relax.app

Output in Console.app:

4/4/12 12:15:26.639 PM [0x0-0x18a28a1].com.nmr-relax.relax: Traceback (most 
recent call last):

This is a problem related to Carbon support in 32-bit vs 64-bit Python. I
can reproduce this on the command line in 10.6 and 10.7 like so:

 $ type python
python is hashed (/usr/bin/python)
 $ python
Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
> > > from Carbon import Evt
> > > Evt.TickCount()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'TickCount'

And it's because the 64-bit Python doesn't have full Carbon support:

 $ export VERSIONER_PYTHON_PREFER_32_BIT=true
 $ python
Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:06) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin

Similar thread here:

I can run the relax binary directly if I force 32-bit:

 $ arch -i386 relax.app/Contents/MacOS/relax

And I can get the relax.app bundle to work if I lipo the relax binary:

 $ mv relax relax.orig
 $ lipo -thin i386 -output relax relax.orig 

I tried various other ways of forcing 32-bitness for Python: lipo'ing the
python binaries, export VERISONER_PYTHON_PREFER_32_BIT=true,
LSArchitecturePriority in the Info.plist without effect.
