An update: I deleted the "--with-curl" line, and started compiling. This time, it errored on the yp/nis support, so I deleted the "--with-yp" line, in php.spec. Now when compiling, it's been dying on the sybase portion. It can't find libraries. I downloaded and installed Sybase ASE-12_5 for Linux, since it's free, not only for the client support, so I can connect to existing Sybase databases on other machines, but also for the opportunity to mess with a Sybase database. Anyway, I installed ASE to /opt/sybase, it's default location. When PHP compiles, it expects to find various .h files in /opt/sybase/include. Guess what, it doesn't exist. After hunting around, I found the .h files in /opt/sybase/OSE_12-5/include. So, I'm in the process of compiling again, waiting to see the results. I'll let you know. Thanks, Chris
