Subject: [PATCH] fix dlerror when using dlopen with a static libc
Date: Thu, 7 Aug 2014 17:49:29 +0200 [thread overview]
Message-ID: <1407426569-78240-1-git-send-email-clement.vasseur@gmail.com> (raw)
when the dynamic loader is disabled, dlopen fails correctly but dlerror
did not return a human readable error string like it should have.
