Porters, I spent sometime trying to figure out why dlsym() was not working on handles obtained by calling `dlopen(NULL, flags)' -- i.e. on a handle to the ELF executable itself. It turns out that you need to link the final executable with the `-E' option (--export-dynamic) under ELF to allow symbols defined in the executable to become visible to the `dl*' family of routines. This behaviour is not the default for ELF. This wasn't very obvious (at least to me). I was wondering if anyone else had encountered this stumbling block. Do you think it is worth a FAQ entry?
