I have followed all the steps to install APACHE1.3.12/PHP4 Release2 modules version on Linux (Redhat 6.1). My purpose is to access an ORACLE 8.1.5 database from a web server.
I get a successfull result when I build PHP with APXS support.My option are as follow :
./configure --prefix=/home/php/Packages/php-4.ORC2 --with-apxs=/home/apache/Packages/apache_1.3.12/bin/apxs --enable-tracks-vars --enable-debug --enable-trans-sid --with-oci8 --with-xml --quiet

Then I try to install PHP and get an error message when I try to install PHP with APXS support : "
