I'll try changing the order of the libraries as you suggest. As for telling the linker that I wanted a static link, I am doing the project in Eclipse and put it in the flags area. It comes out in the compile:
g++ ... -O3 -Wall -static -c -fmessage-length=0 I do want the executable to be as nearly self-contained as possible. Should I do something to get it into the link statement as well? I don't honestly know much about Linux, Eclipse, or OpenSSL, but I would like to learn. Do I need the static flag both places? Thanks to all of you for your continuing help.

This is some very useful information and more than I knew.

Will -lopenldap work better? It is hard to say without seeing your full command input and he output of where the linker is looking for libraries and n what order. __order matters__ > link to OpenSSL first, and then OpenLdap (order matters): > gcc ... -lcrypto -lopenldap If doing the linking with the compiler driver, add: Wl,-t o the command options so the linker will output each library s it searches for symbols. If calling the linker directly, just add: t o the link command options The "-t" option is the "trace" option to the linker.
