configure/compile universal binary mac

Hi - I just joined the list today because I'm having problems building
a python extension that uses taglib.  I checked the list archives prior
to posting my question and I was very happy to see this thread.

I was able to build a universal version of the dynamic library using:

env CFLAGS="-arch i386 -arch ppc" LDFLAGS="-arch i386 -arch ppc"
./configure --disable-dependency-tracking

I could build the python extension using the resulting dynamic library,
but I got the following error when importing the module in python:

  ImportError: dlopen(/Library/Python/2.5/site-packages/_myreader.so, 2):
Symbol not found: __ZTIN6TagLib3MP43TagE

I tried to build the static version by adding --enable-static to the
configure command above, but the resulting libtag.a was i386 only.

I was able to get the python extension working by using the libTagLib.a
posted earlier, but I still can't build the static library myself.

Does using qmake with taglib.pro replace the configure step?

Is there something wrong with the taglib.pro file that comes with
taglib.1.6.1 that I downloaded a few days ago?


Thanks,
