To anyone that may be interested... I've managed to build omniORB with VC7 using a prepackaged Python distribution (ActivePython 2.2.1) using a quick hack: I've rebuild the python22.ddl from sources using VC7 and substituted the original DLL that came with the binary distribution. If anyone is interested in the new DLL, I could post a link to it. Cheers, Sandro Tolaini.
