This is not a problem with compiling python extensions, this is a problem linking to the mysqlclient library. Check out the comments on this page: http://dev.mysql.com/doc/refman/5.1/en/windows-client-compiling.html Unfortunately I can't try anything out for you since I don't have a Windows machine anymore (changed jobs). -Chris On Fri, Dec 08, 2006 at 02:24:58PM -0700, Robert McFadzean wrote:

I have tried a number of the suggestions on getting the minGW32 compiler to build python extensions, but I still get the same hangup which seems to be here:

d:/mysql/lib/opt\mysqlclient.lib(./release/my_thr_init.obj)(.text[_my_thread_glo bal_init]+0x1e):C:\cygwin\home\mys: variable '_iob' can't be auto-imported. Plea se read the documentation for ld's --enable-auto-import for details.

And I don't know what that means other than that it proceeds with a lot of warnings, tries something else, and then gives it up.

I have been trying to build MySQLdb for python and A. Dustman has come to the conclusion that the minGW32 compiler that I am using will not work with a Windows ( os is Windows XP) versions of Python and MySQL. Can anyone here confirm that he is right. Is there a possible work around? Dustman suggested that I would have to compile Python and MySQL with the gcc compiler for it to work. A quick search finds a plethora of resources for how to use mingw to compile

Many of those are out of date and some steps can be skipped and either the export file is actually shipped with 2.4 and 2.5 or mingw32-gcc just deals with it interally. I haven't done this in a while, but, I think all you really need to do at this point is:

python setup.py build --compiler=mingw32 python setup.py install

Note, you can make the '--compiler=mingw32' a default setting by adding """ [build] compiler=mingw32 """ to c:\Python2x\Lib\distutils\distutils.cfg, at which point all you have to do is: python setup.py install

I don't know any details particular to building MySQLdb.
