From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1)

Description of problem:
For my application, I need to link libdl.a, which contains a symbol
(_dl_load_lock) that is only in the static versions of libc (libc.a,
libc_p.a) and is not in libc.so.

Why is this so?

Comment 1 Jakub Jelinek 2004-05-17 06:52:10 EDT
Is it statically linked program or dynamically linked?
In any case, _dl_load_lock is/used to be a glibc private symbol and no application
nor third party library should ever use it.
See dl_iterate_phdr API for querying loaded libraries in a program.
If your application uses it, it should be fixed, if some third party
library uses this, you should file a bugreport with the third party
library provider.
