So I wrote a wrapper object that would try to load the module and store it as a local attribute. I made my wrapper object implement functions like __getattr__ and pass any unknown calls into the module object itself, making the wrapper object act as if it was the module, but having extra capabilities, such as being able to tell me if the module had actually loaded or not.

So look into the mingw cross compiler. Usually you have to build it yourself. see http://www.torriefamily.org/~torriem/cross for more information. The information on the windows target is in the second half of the document. This document used the OS X as the build host, but the same steps work on linux. I prefer to use /usr/local or /usr as my prefix (ending up with /usr/local/bin/i386-pc-mingw32-gcc etc) Michael In Windows, things aren't so simple. I'm immediately bedazzled by a vast, unfamiliar nomenclature: VC6, VC7.1, msvcrt, msvcr71, msvcr80, VS2005, VS2007, MSVC2003, MSVC2005, Express Edition, .NET SDK, etc. The python.org recommended compiler is apparently no longer available, but someone posted a link to an obscure Microsoft webpage artifact where it could still be obtained. Running it under WINE is less than ideal, but I decided to try and make it work. However, when I tried installing the compiler, it failed because my Internet Explorer [was] out of date. I'm not sure how IE comes into the picture, but I'm just a programmer, after all. I am further confused by the python.org docs on using MinGw to build extensions: These instructions only apply if you're using a version of Python prior to 2.4.1 with a MinGW prior to 3.0.0, but further on: pcexports python25.dll python25.def seems to contradict that. It really makes no difference. The referenced webpage where the pcexports tool is found seems defunct. My main problem is that I don't really grasp the big picture. Can someone give me an overview of the requirements to build extensions for Windows Python, circa 2.5? Or, can I tell my employer she'll just have to hire/contract a Windows expert to do the mud wrestling? Jim Wilson Gainesville, FL -- http://mail.python.org/mailman/listinfo/python-list
