This is the custom build native libraries for released and SNAPSHOT versions. Currently the configurations that are supported but not frequently used (and tested) can be found here: win32-cdc - For SUN CDC when running on Windows 32 XP/Vista (native functions exported using __cdecl calling convention) vista-broadcom-6 - For L2CAP support using WIDCOMM stack v6 on M$ Vista (compiled using BTW-6_1_0_1501-SDK) If required the standard native libraries for released versions should extracted from distribution bluecove-$VERSION$.jar Ideally the libraries in this directory should be produced by bluecove build process running on Windows XP in VMware-player on the main pyx4j.com Linux build server. The only problem is that Mac OS X Leo does not run under VMware for me But this may change soon.
