note 24506 rejected from install.linux by jmcastagnetto

I downloaded and installed apache 2.0.39, mysql (the 3.xx.51 build), both of which work and also downloaded the PHP4.2.2 tar.gz. Apache and mysql work fine. However when I try to build and install php from source using ./configure, it does some initial building and then gives the error "httpd.h not found". I know that this file does exist in the apache ../include directory. I am using the following options with ./configure: ./configure --with-apache=/mypath/to/apache --with-mysql=/mypath/to/mysql which is when this error comes up. Also I want to configure it as a dynamic module (DSO), and i've heard you have to do this with --with-apxs=/mypath/to/apxs, which i tried without success. It also says that you cannot use the --with-apache and the --with-apxs together. Any ideas as to how I should proceed? mod_so is installed so DSO should be possible. Thanks in advance...
