    export CC=/usr/bin/gcc-3.2.3

    and compile, if that doesn't work paste the output of

    ls -al /usr/bin | grep -i gcc

    when I run gcc -v I get the following

    [root@xxxxxx mod_evasive]# gcc -v
    Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs
    Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/u

    Thread model: posix
    gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53)

    so I think I might have gcc installed in different location other than /usr/bin/gcc-3.2.3 am i right?

    I've used this in the passed and it had got all messed up when I had clients with sites that generated images via php. So say a site with a ton of images that are .php then grab the images in order to prevent hotlinking.

    So anyone who uses it now have you had any issues like this?

    Rules? What are you referring to?

    There is no such thing as 'rules' for mod_evasive.
