Jambi on the Mac

Message 1 in thread

    I'm trying to develop a QtJambi application the Mac.  I installed
QtJambi and the demos run fine.  However I'm unable to run or debug even a
HelloWorld app from inside either NetBeans or IDEA.  I get this error

Exception in thread "main" java.lang.UnsatisfiedLinkError: __qt_initLibrary
    at com.trolltech.qt.core.QtJambi_LibraryInitializer.__qt_initLibrary(Native
Method)
    at com.trolltech.qt.core.QtJambi_LibraryInitializer.<clinit>(QtJambi_LibraryInitializer.java:10)
    at com.trolltech.qt.core.QAbstractFileEngineHandler.<clinit>(
QAbstractFileEngineHandler.java:43)
    at com.trolltech.qt.QtJambi_LibraryInitializer.<clinit>(QtJambi_LibraryInitializer.java:25)

    at com.trolltech.qt.QtJambiObject.<clinit>(QtJambiObject.java:27)

If I copy the exact run command to a shell it works fine.

Here is what I have tried/done

set DYLD_LIBRARY_PATH and LD_LIBRARY_PATH in /etc/profile to include the
jambi lib directory.

Added -Djava.library.path=.../qtjambi/lib to the vm arguments for the jambi
app (along with -XstartOnFirstThread)

Modifed the Info.plist of the IDE to add -Djava.library.path

Created symlinks from qtjambi/lib to /usr/java/lib, /Library/Java/Extensions


It seems that on the Mac, Netbeans and IDEA do not cause a shell to be
launched when a progam is run.

I could just run it from the command line, but I lose the ability to debug.

I tried the guys at JetBrains/IDEA but they gave up pretty fast.

Any ideas ?

Thanks in Advance

Hi James,

You can try specifying -Dcom.trolltech.qt.verbose-loading=true as well 
in the VM parameters. That would give you slightly more information on 
where Qt Jambi tries to load the libraries and in particular, which 
libraries fail...

You have three '.' here? Was that intended? I also don't know what these 
IDE's treat as their current directory so maybe the absolute path would 
be better.
