That cannot work, you do not link against any library.

What about about reading the documentation?
I think you will at least need to link against ldapsdk with “-lldapsdk”.

The other question is, do you really need what you downloaded for your task?
What is not included in openldap and the ldap development libraries that
you need to use what you try to use?

It sounds like you need to step back from using LDAP libraries and learn
more about programming in C/C++ first. Linking against libraries is a
fundamental skill in writing and compiling C code.
