As Paul said, you can use DF_1_NODELETE on libraries that you don't want to unload ever, or if a library (libfoo) in this case performs a cal to a function from libbar, it will have a dynamic dependency on libbar through symbol resolution and thus would allow libbar to be unmapped only when libfoo is about to go away too. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
