How to use the libstdc++5-dbg package?

[Phil Edwards <phil@jaj.com>]

After setting LD_LIBRARY_PATHY to /usr/lib/debug, and firing up the
debugger, I can see that the correct libstdc++.so is being found (i.e.,
the one with the debugging symbols).  And stepping into those functions
works, in that it knows the file/line location.

However, the debugger can't print any useful source, because of course it
doesn't know where to look to get the libstdc++ source, which makes the
dbg package much less useful.

Am I missing a package?  I know enough about the libstdc++ source (*cough*
:-) to know that simply pointing ddd/gdb at the top of the library source
tree won't work, because the files are renamed during build and install.

Is there a "source package for use when debugging"?


Thanks,
Phil
