The ./configure worked fine. I didn't see any error messages, but when I ran make, I got the following:

That makes no sense to me, so all I can say is, please help

Thanks

I had a similar problem. It compiled with latest development PHP version.

So you used php 4.2.2 or some beta thereof? Ok thanks for the help.

Thanks again,Mara. That did the trick.
