Re: [Valgrind-users] GUi on top of valgrind

[Jeffrey S. <fe...@xi...>]

I've actually already started working on a valgrind frontend for Gtk.

http://primates.ximian.com/~fejj/alleyoop-0.1.tar.gz

I don't think that's the latest sources, but it should be close enough
for you to get a feel for what I am doing.

this is how I did it :-)

however... speaking of front-ends for valgrind - would it be possible
for the valgrind developers to add a switch such as --full-src-path or
some such that would give the full path name for the src file in the
error log output?

currently it only gives the basename of the src file containing the
brokeness. I've taken a look at adding this myself (to 1.0.4) but got
lost in the valgrind sources for parsing ELF (symtab2.c or some such if
I recall correctly).

from my limited understanding of ELF (mostly from playing with libbfd),
the debugging symbols which would give what I want (full src path) lies
within the "text" section - but it appears that is not what valgrind
uses (probably for a good reason, just that I don't know what that
reason is).

the other path I was thinking of following was to use bfd myself, but
that means that I would have to figure out which .so each address was
in. it also means (logically) that I would have to open each of the
dependency .so's in libbfd so that I could extract the debugging symbols
I needed. kinda yuck, but ya gotta do what ya gotta do I guess :-)

not that I know of.

are you using --alignment=8 ? I had to do this when valgrinding
evolution.
