Re: Fwd: Slight Issue installing mod_security

The Lua source does not build shared libraries (/usr/lib/liblua5.1.so),
but only static libs (/usr/lib/liblua5.1.a).  ModSecurity requires the
shared libraries.

If you do want Lua support (you do not unless you are going to write Lua
rules yourself).  Then you need to install the binaries from the Lua
site, or build the Lua shared libs yourself.  You can do this to build
the shared libs:

ModSecurity with something like this:

"/usr/local/lib/liblua5.1.so", nor "/lib/liblua5.1.so". I then searched for anything matching
*lua* in /lib , /usr/lib , and /usr/local/lib , and only found /usr/local/lib/liblua.a . There is also a
directory /usr/local/lib/lua/5.1 , but it is empty.
