I only mentioned MinGW because MinGW (and Cygwin) are the only ports of gcc I know of that work on windows. But I realize that these have an older version of gcc built into them. The reason I posted to this mailing list was to find out if the current version supported x86-64 platforms, and if so, then I would be interested in building the latest version. And I did spend two days searching (and trying out possible) solutions before posting to this list.

Thanks for pointing me to the mingw-w64 sourceforge project. As Tim said, there isn't much documentation available for it, so I guess I'll just download and try it out. Although, at this point, I'm just thinking that downloading a trial version of Visual C++ and using it to compile my dll would be much easier :(. But even with that option, I'm not sure if its legal to distribute that dll with our package. > Ali didn't say if he meant g++ rather than gcc, but I guess all of this > has missed his intended topic. gcc. I'm working with a java application which is using JNI to call native libraries. We want to port our software to 64-bit platforms, and hence here I am, trying to figure out how to compile 64-bit dlls on my amd64. Thanks for all the comments, Ali.
