Building with IMAP support

Hello: I'm new to the list, please excuse me if this has been covered already, but I haven't found what I'm looking for online or in the archives. I'm trying to install PHP-4.0.2 with IMAP support, with the following configuration: - RedHat 6.1-based linux system - Apache 1.3.12 - PHP 4.0.2 - imap c-client , imap-2000.RELEASE-CANDIDATE.7 (built with make slx) I'm compiling mod_php as a static module, and it appears to build without issue, finding the IMAP c-client libraries and headers without a problem. However, I get what appears to be a crash when I run a simple test (with a real nntp host, user and password supplied): <?php echo "<!-- Before imap_open -->"; $imap = imap_open("{x.x.x.x/nntp:119}","xxxx","yyyy"); echo "<!-- After imap open -->"; ?> The output shows the first echo statement, but not the second, and so the script appears to just quit or crash. Nothing is showing up in the apache error_log , system log or browser to indicate an error or crash. I'm having no problems with the rest of the PHP build (as far as I can tell), but am fairly new to PHP, so: - where are the error messages going, if not the server error_log or /var/log/messages? - have I missed something in the configuration/build process? - if the imap extension is causing a segfault or something, where would the core file be written?
