Re: Soot on OS X?

[Derek Rayside <drayside@mit.edu>]

Hello,

Yes, the soot-class-path doesn't really have anything to do with the OS.
My understanding of Will's problem is that he couldn't find rt.jar, so he
couldn't set his soot-class-path properly.  The reasons he couldn't find
rt.jar are, in this case, OS dependent:  1) Apple renamed it classes.jar;
2) the CLASSPATH variable is not set by default on OSX; the Java VM just
knows where to find classes.jar (even though Soot doesn't).

So even if soot-class-path defaults to CLASSPATH (as I believe it does),
that doesn't help someone on OSX.  In fact, on my OSX installation, there
are no Java related environment variables set in the shell.  And the Java
system properties java.home, java.class.path, java.library.path, and
java.ext.dirs, do not tell where the classes.jar is hiding (although they
give some clues about where to look for it).  So Soot has no way of
automatically determining where classes.jar is on OSX.

Derek.
