So hard installation on Mac OS

[blaurent]

Hi,

I have so many problem to install MySQLdb on Mac OS X 10.5.8.

The real problem occurs during the build phase (see message below).

Python is standard Python2.6 for Mac OS and MySQL is a 32-bits 5.1
distribution.

Help me please : I'm quite desesperate !!!

gcc -arch i386 -arch ppc -arch ppc64 -arch x86_64 -isysroot

Try using MacPorts:

http://www.macports.org/

Then:

sudo port install py26-mysql

There is definitely an architectural mismatch going on, though. Nothing really
I can do about that. If you are using a 64-bit Python, you need 64-bit MySQL,
and that's all there is to it.

Oh, and if you wanna know ahead of time which architecture is which, use this
command:

file /Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6

(depends on where you have python installed, of course)

[John Stoner]

OK... that doesn't help me. I have the same problem. It's not a 32/64 bit
issue. Tried the macports approach, made no difference for me. This is on
10.5.8 as well.

file /Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6

/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6: Mach-O
universal binary with 2 architectures

/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 (for
architecture ppc): Mach-O executable ppc

/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 (for
architecture i386): Mach-O executable i386

file /usr/local/mysql/bin/mysqld

any ideas?

aack--on review, maybe its not the same issue. But macports didn't help,
anyway.
