From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830 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? Thanks. Version-Release number of selected component (if applicable): glibc-2.3.2-95.17 How reproducible: Always Steps to Reproduce: used nm to verify this. Additional info:
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.
