How do I upgrade gcc/g++ on a Mac

[Gordon Prieur]

Hi,

    We have 2 different Macs, both running 10.4 OS but different builds 
of the
same versions of gcc/g++/gdb. With the older set of tools we see gdb 
failures
debugging some C++ applications (faulty line table information). Debugging
the same program on with the later builds, works fine. We've tried the 
automatic
update service on the Mac but it doesn't update either g++ or gdb.

    Is there a way to get the latest gcc/g++/gdb on a Mac? We're not 
interested
in hearing that we should upgrade to Leopard (we plan to:-) because we're
more interested in what we can tell our customers than how anything else. We
provide a gdb-based C/C++ debugger in NetBeans 6.0 and this Mac bug makes
our debugger fail. If we could tell customers how to upgrade their compilers
then that would resolve the issue.

Thanks,
Gordon
