Hi all, Well i'm worrying about an error message preventing the config.cache file to be created: I'd like to compile with the options above: cd ./php-4.0.4pl1; clear ./configure --prefix=/u/PHP4 \ --with-mysql=/usr/local/mysql --enable-force-cgi-redirect \ --with-apxs=/home/apache_1.3.14/bin/apxs \ --with-java=/usr/java1.3 --enable-inline-optimization At the end of the ./configure i obtain such a message: ../.. creating regex/Makefile creating main/internal_functions.c +--------------------------------------------------------------------+ | *** ATTENTION *** | | | | Something is likely to be messed up here, because the configure | | script was not able to detect a simple feature on your platform. | | This is often caused by incorrect configuration parameters.

No output written to conftest collect2: ld returned 1 exit status What does the blue text means ? Assuming that i run apache 1.23.14 with mod_jk and mod_perl that i need MySQL running against Perl and PHP... I found out a method which consist first running my compilation of PHP parsing --with-mysql without indicating a DIR; so that i obtain an error message saying that if i want to make PHP running MySQL with stuff like mod_perl in apache, i would better use my local installation Dir of MySQL ( which is in my case /u/MySQL ) so i don't rm anything (like config.cache) and run again ./configure parsing --with-mysql=/u/MySQL and things go OK ! Is that a good way to make what i want ??? I don't really know what to do . Thank you for helping. Friendly yours JLB ;O)
