Has anyone succesffuly installed PyODBC on snow leopard?

I'm getting the error below. (I also submitted a bug here too) Any ideas how to fix this and get it installed?

Here is the output I'm getting:

Versions: PyODBC 2.1.8, Mac 10.6.7, and Python 2.6.1

Answer 1

Your problem is likely the combination of xcode 4 and setuptools. See this error:

/System/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6/datetime.h:186: warning: ‘PyDateTimeAPI’ defined but not used
/usr/libexec/gcc/powerpc-apple-darwin10/4.2.1/as: assembler (/usr/bin/../libexec/gcc/darwin/ppc/as or /usr/bin/../local/libexec/gcc/darwin/ppc/as) for architecture ppc not installed
Installed assemblers are:
/usr/bin/../libexec/gcc/darwin/x86_64/as for architecture x86_64
/usr/bin/../libexec/gcc/darwin/i386/as for architecture i386

setuptools tries to compile for ppc but xcode 4 no longer supports it.

Try compiling like this:

ARCHFLAGS="-arch i386 -arch x86_64" python setup.py install

I use macports to install pyodbc

sudo port install py26-odbc

py26-odbc is for python 2.6. If you use Python 2.7, the name would be py27-odbc
