VR Juggler

Tweek is optional depending on the availability of its dependencies.  
If the JDK isn't available, then the Java components will be skipped.  
If omniORB isn't available, then the C++ component will not be built.  
Without Tweek, you won't get run-time reconfiguration or VRJConfig,  
but it sounds as though you're OK with that.

my problem is that I have a Java runtime, but not the javac compiler. With this 
configuration compilation stops when it tries to compile the java parts of tweek...

I just installed the JDK to get around that for now, just FYI.

The configure script fails entirely? It shouldn't do that. The idea was that 
failure to detect javac would mean that the JDK wasn't available. The logic 
of the detection can get screwed up by environment variables and command 
line options, however. This is what the test does to figure out if the JDK 
is available:

    1. Search path given on the command line (--with-jdkhome)
    2. Search in the path(s) given as arguments to this macro (DPP_PATH_JAVA)
    3. Search in $JDK_HOME (if it is set)
    4. Search in the user's path
    5. Search in a preset list of common locations

If you have JDK_HOME set to point at a JRE installation, that might be the 
cause of the failure.

OK. Sorry for the headaches related to this. Cross-platform JDK detection is 
hairy to say the least, and the detection tests haven't been updated in a 
long, long time. There may be ways to simplify or improve them.
