Q: RUNPATH missing in libsmbldap.so but not other executables/libraries?

[Michael Tokarev]

Hi!

In debian we've got a bugreport about one of the samba libraries missing RUNPATH
to the private library directory (where libreplace-sambae.so libsmbd-shim-samba4.so
etc are located.  This one is libsmbldap.so.2.1.0. And indeed, unlike all other
libs and executables, this one lacks RUNPATH section, while all other binaries
does have it.

$ ldd /usr/lib/x86_64-linux-gnu/libsmbldap.so.2.1.0 | grep found
	libsamba-debug-samba4.so.0 => not found
	libreplace-samba4.so.0 => not found
	libsamba-security-samba4.so.0 => not found
	libsmbd-shim-samba4.so.0 => not found


$ objdump -p /usr/lib/x86_64-linux-gnu/libsmbldap.so.2.1.0  | egrep 'RUNPATH|RPATH|NEEDED' | grep samba
   NEEDED               libsamba-util.so.0
   NEEDED               libsmbconf.so.0

   NEEDED               libsmbd-shim-samba4.so.0

while other libraries and executables:

   RUNPATH              /usr/lib/x86_64-linux-gnu/samba


How come this single library (libsmbldap.so) does not have a RUNPATH specified
but all the other does?

Thanks!
