no -- there is C code that needs to be compiled, I"m pretty sure anyway!
maybe I'll get a chance to try it myself.
I.e., that given
a suitable portable mysql client library, MySQLdb will Just Work?
that would be great, but no, I don't think so.
But OK, now this brings up the question of why my
libmysqlclient_r.16.dylib is Intel-only, when I took pains to install a
UB version of MySQL (c.f. the "Installing MySQL" section of
<http://www.dotancohen.com/howto/python-app-mac.html>). (I'm going to
do a fresh download of that mysql binary package and poke around inside
to see what I find.)
You can find what it builds in the "build" directory that distutils
creates when you run "setup.py build". It will be in something like:
build/lib.macosx-10.3-ppc-2.5
and I think will be called -mysql.so
But now I'm confused again. I thought this library was part of the
mysql distribution -- not something created by the Python script
"libmysqlclient" is part of mysql. I"m pretty sure that the python
module requires a compiled extension, that links against it, and it will
be called something like _mysql.so, and should get put in the build
directory when you built it, and installed somewhere in site-packages
when you install it.
Thanks for your patience,
no problem -- this really is complex!
/Users/jstrout/Downloads/mysql-5.1.30-osx10.4-universal/lib/libmysqlclient_r.16.dylib:
Mach-O dynamically linked shared library i386
So it turns out that the 10.4 Universal mysql isn't. (Or at least, this
particular library isn't -- perhaps there's another library in here
somewhere with a different name, that serves the same function for PPC?)
could be -- I'm just guessing here, but I suspect that libmysqlclient
may be used only for custom clients, so it may have gotten built
non-universal and no one has noticed. What do the other libs in there
look like?
