Build and Run problem in xcode...

[Charles E. Heizer]

Hello,
I'm brand new to C and ObjC using xcode, i've been in java land for a  
while and I wanted to do something new.

So, I found some example code on using ldap api and wrote my little  
test tool which connects to our ldap(AD) server and will do a query.  
The app appears to compile just fine but when I run it I get a error:

ZeroLink: unknown symbol '_ldap_open'

LDAPCall has exited due to signal 6 (SIGABRT).

Can someone please tell me what I'm going wrong.

Thanks,

Charles
