Re:

Thanks.  I assume this means I should have a file on my system named libpq.  If so, I can't find it. Where should it be
located? If I don't have it, where can I get it?  Is there an rpm somewhere that has development libraries?  I have
checkedout the rpms on my redhat cd's and I can't find it there either.   

Also, should my command look like this?

  gcc -Wall -o test1 test1.c -lpq

I have the include file. It is in /usr/include/pgsql/libpq-fe.h.

Thanks again.
