Don't know about the others, but... alcapcom wrote: > 2. aot-compile-rpm tool create only one .so file for 3 jar files, is > that ok? That's ok. If you look you'll see subset warnings for the other two: aot-compile-rpm: warning: subsetted /path/to/3ddesktop-info-0.1.jar aot-compile-rpm: warning: subsetted /path/to/3ddesktop-switch-0.1.jar A subset warning basically means that all the classes in one jarfile are contained in another. You only need one compiled copy of a class on your system, so it doesn't bother to compile the duplicates. Cheers, Gary
