Ok, I wasn't specific enough. Sorry about that. What I meant with doesn't work is: it doesn't load the symbols. I have now tried gdb /usr/lib/debug/usr/bin/kmail pid, and this gives me the symbols for the main binary (and if pwd is ok or I add -d path to the cmdline, it even shows the source code, so that's fine, too), but for all the shared libraries, I'm still stuck. add-symbol-file wants an address (where would I get this?); plain symbol- file crashes gdb (and in any case: wouldn't this *replace* the symbol table instead of add to it?) cheers -- vbi -- Anyone can invent a security system that he himself cannot break. -- Schneier's Law signature.asc Description: This is a digitally signed message part.

Just gdb -p pid /usr/bin/kmail doesn't work :-( Just don't specify any binary to the gdb command line. Let it find the correct binary from /proc: $ gdb -p pid This is because sometimes kdeinit4 is the binary and the application is loaded as a shared library and gdb gets very confused if you tell it where the binary is. Also, always make sure that the debug symbols package is exactly the same version as the package providing the binary. In some debug packages dependencies are not strict and you might get version mismatch. Regards, George -- To UNSUBSCRIBE, email to debian-kde-requ...@lists.debian.org with a subject of unsubscribe.

Attach gdb to program?
Heyho! Given a Debian package (kmail, in this case, with installed kdepim-dbg package) and an extracted source package: how do I properly start gdb (or ddd or ...) so that it finds both the debugging symbols and the source code? Just gdb -p pid /usr/bin/kmail doesn't work :-( (I've only ever used gdb on locally compiled simple projects, I've never worked with the separate symbol files as delivered in -dbg packages.) thanks in advance -- vbi -- Wer sich an eine falsche Vorstellung gewöhnt, dem wird jeder Irrtum willkommen sein. -- Goethe, Maximen und Reflektionen, Nr. 1026 signature.asc Description: This is a digitally signed message part.
