php + informix

Hello, I am running Informix version 7.30.UC1 on Solaris 7 Intel. I am trying to compile PHP 4.0.6 with informix support. I am running: ./configure --with-informix --with-apache=../apache_1.3.19 --enable-track-vars but in the script it breaks on the esqlc check. I went through my Informix SE and Informix SQL cds but I do not have any esql or esqlc files on it. I also went to www.informix.com/evaluate and saw that the Client SDK 2.70.UC1r1 for SUN Microsystems Sparc Solaris 7 has esqlc in it. But that package is for Sparc Solaris 7 and I am running Intel Solaris 7. I tried it anyway but on the esqlc check it prints a couple of garbage chacters and then errors out. Can someone tell me where to find esqlc? Since its not on my Informix cds nor at www.informix.com/evaluate, do you know how I can find this file or if its in another downloadable package at informix's web site. Thanks, Adam Williams awilliam@mdah.state.ms.us
