Re: [Jepp-users] Problem with JRE 1.6 (64 bit) + JEP (2.4)

[Mike J. <mi...@pu...>]

Hi,

You'll need to see the mingw faq: http://www.mingw.org/wiki/FAQ in the section called "How do I create Python extensions?"

Run pexports and dlltool to create the files you'll need to link with on both the python dll and java. That should solve your link problem.

Mike
