Installation problem

Hi there, Already three weeks I try to setup a WEB server with PHP4 (XML support) and some database support. I'm running a Slackware 7.1 box (kernel 2.2.16 glibc 2.1). I could install apache with mod_ssl, mod_perl and mod_so static successfully. The WEB server runs fine with this enabled. I' ve up and running MySQL and PostgreSQL. So I try to set up PHP4 as a DSO. If I configure --with-mysql=/path/to/mysql ( here are the complete switches: --prefix=/usr/local/php --mandir=/usr/local/man --with-apxs=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --with-config-file-path=/etc/php ), copy ${PHPSRC}/php.ini-dist to /etc/php and add LoadModule and AddType to httpd.conf, apache segfaults for every client request. If I configure --with-pgsql=/usr/local/pgsql (this is the only change in the configure switches above), configure warns me, that I have configured WITH MYSQL (!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!), and that I should add the path to MYSQL. BTW.: If I don't add any --with-some_DB switch to configure, I get the warning above. Does configure ignore my switches completely????? The result is always the same ... segfault on demand ... :o( Nevertheless -- could anybody give me a hint, how can I set up apache with ssl, perl and php4 (best fit MySQL enabled)? Thanks for every help and a merry christmas Frank
