Do you have an ELDK version of glib2-devel installed?

This is the correct thing to do, unless there's an ELDK *cross- 
development* package of Bison (i.e., one that installs a version of  
Bison that runs *ON YOUR PC*, *NOT* on the PPC 4xx target).

Same as with Bison.

This is probably the correct thing to do, for the same reason.  The  
trick is that pkg-config is a framework for dealing with various  
packages, so the question is where it should look for the pkg-config  
information for those packages?  Should ELDK have a cross-development  
version of pkg-config, that looks, by default, for pkg-config  
information in a location separate from where the "native" pkg-config  
looks, or should it use the "native" pkg-config but with the  
appropriate environment variable set to look in the location for the  
pkg-config information for the ELDK target versions of the packages?

This is not useful for cross-development, as it will install a native  
version of glib2-devel.

Cross-development is usually harder than native development, as the  
issues listed above indicate.  You should probably ask the DENX people  
for advice on this; the details of how to do cross-building of  
Wireshark, or any other program, depends at least as much on the  
particular cross-development environment as on the program, and I've  
never done cross-development with ELDK, so the DENX people are  
probably at least as likely, and probably more likely, to know what  
you will need to do to set up a cross-building environment for a GLib- 
based application such as TShark.
