That looks like a classical name clash between C header files. It also suggests that you have 64-bit client libs of MySQL installed. > I assume that's because MySQLdb wants to get settings from the > mysql_config file and the database is compiled in 64 bit mode whilst by > default python seems to be building 32 bit. As long as the MySQL client lib is built as 32-bit lib, you shouldn't have a problem. > Is there some magic I can try to make the OS 10.5 build as 64 bits? I > don't see any options to do that in the configure script. The config options --with-universal-archs is used for this. In theory you could build a 4-way binary for Intel,PPC/32-bit,64-bit.

As long as the MySQL wire protocol doesn't get in the way, this should be possible - again, provided you compile the MySQL client libs as 32-bit. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Oct 23 2008) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ :::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
