My thanks to everyone who emailed suggestions and solutions. Since people are still emailing me regularly to ask if I found a solution, I thought it would be better to post the answer.
Apparently the configure script gets confused because it can't find the Sun compiler cc. The simple solution, which I have not tried but I am assured works, is set an environment variable CC=gcc before running configure. Before being told this, I had discovered (with the help of a few hints from around the world) that the solution was to rebuild the configure script: $ mv configure something_else; ./buildconf You need GNU autoconf and automake and maybe other goodies to do this. Finally, I eventually discovered that the problem has been logged to the PHP buglist. Why couldn't I find it when I first looked? I was searching for Solaris 7 and it was logged against a different version... Jon -- PHP Install Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
