See the HTML documentation in the doc-html directory for installation instructions and documentation. If you can't read instructions: $ ./configure --with-apxs=/usr/local/apache/sbin/apxs $ make $ su # make install Edit httpd.conf like instructions at the end of "make install" tell you. If the above worked - read the tutorial in the doc directory. OS Hints: FreeBSD: Apache has to be compiled with threads, even if using the prefork MPM (recommended). In the ports collection, edit the Makefile to add --enable-threads in the CONFIGURE_ARGS section. This has been tested on FreeBSD 4.7; it is possible that earlier versions of FreeBSD may have issues with httpd's use of threads.
