Is it a bug? 'NoneType' and 'NoneType'

[Lukasz]

Hi all
I'm trying to build some small app in XCode - PyObjC+MySQLdb. Everything works great till I try to compile for Deployment.
I tried in Intel and PPC with exactly same result:

Building target “Deployment” of project “Match” with configuration “Deployment”

Checking Dependencies
ExternalBuildToolExecution Deployment
..... thousand of lines here and at the end:

Somebody knows what's going on?

Whatever it is, it doesn't look like a problem with mysql-python. I suggest you ask on the Mac Python mailing list: pythonmac-sig@python.org.

Possible... but this error appears ONLY with MySQLdb... I don't know what to think. Lot of problems with installing MySQLdb, it's why I think problem is somewhere here. Does anybody successfully installed, developed and deployed apps with XCode, python and MySQLdb? Any help appreciated..

I've used MySQL a lot with Python on my Mac. Like most folks I get the compiler tools from the Apple Xcode distribution.

Hi Skip,

I'm hobbyist, using Development tools for "mind training" rather. Last time i had an idea how to improve my office environment - I start to fight more seriously.
First I installed 1.2.2 - with problems, some answers I found on this list, but I couldn't compile.
Next I found nice package for mac. version 1.2.1. Compiling with XCode was possible, but problems with encoding starts: same program worked different way (much worse - unicode) than with 1.2.2. So, i went back to 1.2.2. But after few days of hard fight no result with compiling. It's why I'm suspecting MySQLdb.

What configuration you have? Installing was soothly? Some tricks? I tried on two macs, PPC and Intel with identical (no) result. What I'm doing wrong? :-( Help!
