Slashcode

For others and so I have a log myself here's how I got PHP to work with mod_perl and apache:

Here are the versions of software I used:

Apache 1.3.27
Mod Perl 1.27
PHP 4.3.0

The following needs to be done first so PHP's ./configure doesn't complain:
In Apache directory:

./configure --prefix=<path to apache install> --activate-module=src/modules/php4/libphp4.a --activate-module=src/modules/perl/libperl.a

In PHP directory:

./configure --with-mysql=<path to mysql install> --with-apache=<path to apache root source> --enable-track-vars
./make
./make install

In mod_perl directory:
Edit the Makefile.PL file and look for the line (was line number 1029 for me) that has the following:

$cmd .= "./configure " . "--activate-module=src/modules/perl/libperl.a";

Add this to the end of the quotes (but before the semi-colon):

. " --activate-module=src/modules/php4/libphp4.a"

Save this file and now run this:

perl Makefile.PL APACHE_SRC=<path to apache root source> DO_HTTPD=1 USE_APACI=1 PERL_MARK_WHERE=1 EVERYTHING=1 APACHE_PREFIX=<path to apache install>

The output of the perl command should be something like this:

Will configure via APACI

Take note of these two lines:

+ activated perl module (modules/perl/libperl.a)
+ activated php4 module (modules/php4/libphp4.a)

If those two lines are present then both php and mod_perl will be staticly linked in apache (i.e. no DSO involved)

Now in mod_perl directory:

./make
./make install

The ./make should compile mod_perl and php into apache (basically by running apache's Makefiles) and then ./make install will install apache into the APACHE_PREFIX specified earlier.

Now edit httpd.conf and add or uncomment this line:

AddType application/x-httpd-php .php .php3 .phtml

Now install Slash (and whatever perl modules are necessary). Don't forget to copy PHP's php.ini file to /usr/local/lib and edit it as necessary.
