I recently had a similar need. I found `info proc all` (technically `info proc mappings`) contained the mapping info I needed. For a regular core file the shared libraries were automatically loaded (in my case I needed to `set auto-load safe-path` and `set sysroot` for my cross-build environment). The one slight problem I had was with a very specific core file where the crash was in ld.so in that specific case it wasn't automatically loaded and I had to muck around with `add symbol-file` and manually working out some offsets to get it loaded into the right place. I'd be interested in hearing tips from anyone else. > -- > -- Howard Chu > CTO, Symas Corp. http://www.symas.com > Director, Highland Sun http://highlandsun.com/hyc/ > Chief Architect, OpenLDAP http://www.openldap.org/project/
