So I've spent the past hour or two hammering away at this. Here's what I've
found:
1) The files all appear to be correctly compiled with -g in the build_tree
dir
2) None of the files are stripped in this dir after the build is done.
"file" confirms this, as does the size of the thing (libX11 is 9 megs
in build_tree but the stripped version on my system is 860k or so).
3) The file with the debugging symbols is only 4k. Where'd those 8 megs
go?
4) objdump -g on any of the files in build_tree can't find the debugging
info.
At first I thought it was a problem with dh_strip, but now I'm thinking
that it's an issue with binutils. If anyone else can offer any insight to
this, it'd be much appreciated, since I don't know much about the details
of debugging symbols. I'll probably send a bug to binutils very soon about
this so we can figure out what's going on.
