Installation from GIT with luajit¶

Since 1.4beta Suricata introduces luajit support.
What does this actually mean? - here is a quick look and a repository(EmergingThreats) that holds free to use luajit scripts for Suricata:
https://github.com/EmergingThreats/et-luajit-scripts

This installation guide is for Suricata from git (latest) and Luajit - http://luajit.org/
Set up used is Ubuntu LTS 14.04 and luajit 2.0.3 (latest at the time of this writing)

We get luajit (please do not copy/paste, make sure you check the latest luajit version):

wget http://luajit.org/download/LuaJIT-2.0.3.tar.gz
tar -zxf LuaJIT-2.0.3.tar.gz
cd LuaJIT-2.0.3
make && make install

at the end , when make install is done we should get something like the following:

...

cd src && install -m 0644 lua.h lualib.h lauxlib.h luaconf.h lua.hpp luajit.h /usr/local/include/luajit-2.0
cd src/jit && install -m 0644 bc.lua v.lua dump.lua dis_x86.lua dis_x64.lua dis_arm.lua dis_ppc.lua dis_mips.lua dis_mipsel.lua bcsave.lua vmdef.lua /usr/local/share/luajit-2.0.3/jit
ln -sf luajit-2.0.3 /usr/local/bin/luajit
==== Successfully installed LuaJIT 2.0.3 to /usr/local ====

.......

So far so good. Now we only need to compile and install the latest Suricata form git.
In this particular example we are also using/enabling nss (but you can skip those if you do not need/use them):

sudo git clone git://phalanx.openinfosecfoundation.org/oisf.git && cd oisf/ && \
git clone https://github.com/OISF/libhtp.git -b 0.5.x && \
sudo ./autogen.sh && ./configure --prefix=/usr/ --sysconfdir=/etc/ --localstatedir=/var/ --enable-luajit \
--with-libnss-libraries=/usr/lib --with-libnss-includes=/usr/include/nss/ --with-libnspr-libraries=/usr/lib \
--with-libnspr-includes=/usr/include/nspr --with-libluajit-includes=/usr/local/include/luajit-2.0/ \
--with-libluajit-libraries=/usr/lib/

Then at the end, when it is finished, you should get similar result:
...
