ap_config_auto.h: No such file or directory

Hi Guys I am having trouble installing PHP4.3. I am running SUSE Linux 8.1. I have installed Apache 2, and i installed it using the SUSE2 CDs via YaST2, so I had little control over the configure or install scripts. I configured the install of PHP4.3 successfully vis this command: ./configure --with-mysql --with-apxs2=/usr/sbin/apxs2 --prefix=/usr/local --with-gd --with-png-dir --with-jpeg-dir --with-zlib --enable-sockets However, when I try make, I get the following error: In file included from /home/mwatson/php-install/php-4.3.1/sapi/apache2filter/sapi_apache2.c:35: /usr/include/apache2/ap_config.h:269:28: ap_config_auto.h: No such file or directory /usr/include/apache2/ap_config.h:270:30: ap_config_layout.h: No such file or directory make: *** [sapi/apache2filter/sapi_apache2.lo] Error 1 I do actually have these files, they are in: /usr/include/apache2-perchild/ /usr/include/apache2-prefork/ /usr/include/apache2-worker/ Sounds like my apache installation is not quite the right one - so question is how (exactly) do i get the right one? Thanks for your help Mick
