Compiling ProC (sqlcxt)

I am using Oracle 7.3.2 on DEC unix 3.2. I am trying to compile a simple program use embedded sql C. However, everytime I compile I receive this message: ld:
Unresolved:
sqlcxt
*** Exit 1
Stop.

I have looked in and linked every library I can find that comes with Oracle. Also, I have determined that the link/compile fails only on this embedded command: EXEC SQL CONNECT :user IDENTIFIED BY :passwd; Any help would be much appreciated.
