Re: [mod-security-users] Install Mod_Security 2.5 on OS X LeopardApache 2.2??

[Christian B. <ch...@jw...>]

Hi Douglas,

I am running ModSecurity 2.5 on OS X. It is quite a while ago, since I  
compiled it, so I give no guarantee on the following ;-)

The libxml2 was part of Leopard, IIRC. It is just the fact, that it is  
not called "libxml2.so", but "libxml2.2.dylib". What I did then is to  
create a symbolic link

	ln -s /usr/lib/libxml2.2.dylib /usr/lib/libxml2.dylib

and put the following line into my httpd.conf:

	LoadFile /usr/lib/libxml2.dylib

Note the ".dylib" instead of ".so".


Now, for LUA, I think, I needed to compile this myself as the version  
shipped with OS X was not recent enough (again IIRC).
Compiling LUA however was not a big deal. You need to have the  
readline lib lying around as readline has been bound to GPL and thus  
cannot be shipped with OS X.

Building readline was a problem to me as "make" stops with a linking  
error when trying to link dynamic libraries. So I just built the  
static ones:

    cd /usr/local/src
    wget http://ftp.gnu.org/gnu/readline/readline-5.2.tar.gz
    tar xzvf readline-5.2.tar.gz
    cd readline-5.2
    ./configure --prefix=/usr/local --disable-static
    make
    sudo make install

Then you should be able to build LUA, by wgetting it, unzipping/untar  
and run

     make macosx

This should install LUA below /usr/local. If you want to have it in  
another place, you need to edit the Makefile.
Building ModSecurity then was done the same way as on linux.

If you have any additional questions, just let me know and I will try  
to have a closer look at how I once built it.

Regards,
    Chris
