Hello Chris,

maybe a detailed stracktrace with exception error message could help
us to make sure that we are looking at the right place. The 32 bit JVM
should have worked just fine. It could be that one of the dependency
libraries, such as the XML library, bzip2 or zlib or even the MSVC
runtime libraries is missing, and that is why the wrapper library
could not be loaded.

As to how to build 64bit binaries with cygwin, i would guess just
compile the file with the -arch x86_64 or -arch x64 flag. ut honestly
i'm not the one to ask using g++ on windows :)

cheers
Frank
