Recipe for building php-2.0.1 with Apache-1.3.0 and PHP 3.0

First make sure you have the current source tarballs for all three packages. Start in the Apache directory:

cd apache_1.3.0/src
./Configure

This is done so that a couple of auto-generated header files will be there when you configure PHP3.

Next, follow the standard installation directions for PHP3. Something like:

cd php-3.0
./configure --with-apache=../apache_1.3.0
make
make install

Now the tricky part. PHP2 was written long before Apache-1.3.0 was released, so it isn't quite a smooth as it could be. There is a bug in mod_php.module.in. The trailing " is missing. Edit this file and add that. Then run the ./install program. During the install it asks you for the Apache include directory. It will be something like <path>/apache_1.3.0/src/include. After the install program has finished you will need to edit 3 files. First, edit src/php.h and down around line 95 you will find a line that says:

#include "httpd.h"

Just before this line, add a line that says:

#include "compat.h"

Do the same thing in mod_php.c. Just before the #include "httpd.h" line add #include "compat.h"

The third file you need to edit is src/Makefile. On the CPPFLAGS line around line 47 you will see a line which among other things has a -I followed by the Apache include directory you specified earlier. Add another -I entry with the same path but instead of ending in src/include it needs to end in src/os/unix. For example, on my system this line looks like this after fixing it:

CPPFLAGS = -I./regex -I. -I/usr/local/include/mysql -DHAVE_LIBMYSQL=1 \
-I/export/home/rasmus/apache_1.3.0/src/include -I/export/home/rasmus/apache_1.3.0/src/os/unix \
-DFILE_UPLOAD -DAPACHE=1 -DAPACHE_NEWAPI=1 -DPHPSENDMAIL=1 -DSENDMAIL=\""/var/qmail/bin/sendmail -t"\" \
$(DEBUG)

Now you can run make. It will copy a bunch of files to the Apache src/include directory when it is finished. That is the wrong place for these files. You should copy libphp.a and mod_php.* to the Apache src/modules/extra directory.

Back to the apache_1.3.0/src directory. Edit the Configuration file and at the end add these two lines:

AddModule modules/php3/libphp3.a
AddModule modules/extra/mod_php.o

The type: ./Configure followed by make and you should end up with an httpd binary that includes both the PHP2 and the PHP3 module. You can then set your AddType lines in src.conf to poing .phtml files at PHP2 and .php3 files at PHP3, for example.

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