https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239238 Bug ID: 239238 Summary: ldd(1) showing dependencies for shared objects in same name in library paths instead of in current directory Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: msl0000023508@gmail.com ldd(1) should show the dependencies of the program in current directory; however when a shared object file is given, and its file name is same with another shared object under library path (such as /usr/local/lib /usr/lib /lib), ldd(1) will showing dependencies for the shared object under library path.
