Using ggtags with external source tree

Using ggtags with external source tree

[Glen Stark]

Hi everyone

I don't know if this is better solved using gnu-global or ggtags, but I 
couldn't figure out how to do it either way, so I'm asking for help.

I have two source trees with C++ code in.  One contains external 
dependencies, another contains our code.  For the sake of discussion, 
lets say I want to be able to follow tags into the boost source tree.


So I have:

/usr/local/boost

and 

/home/me/my_project

I can't figure out how to use ggtags to navigate to code in /usr/local/
boost.  Can anyone help me out?

Thanks,

Glen

This is what I use in my .bashrc for Java:

  export GTAGSLIBPATH=/usr/local/unix/java/1.6/classes

and run `gtags' in that directory /usr/local/unix/java/1.6/classes.

Let me know if you run into any problems with the emacs interface
ggtags.el.
