Compile on Centos 6.x? about ndpi-netfilter

[elico]

What have you tried until now?
What kernel are you using?
What output did you got from a build?

[hariesnurikhwan]

I've tried compile using the steps listed in "ndpi.install", and changes few requirement to make it work on Centos

Kernel version
Linux Centos-SG 2.6.32-642.1.1.el6.x86_64 #1 SMP Tue May 31 21:57:07 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

@hariesnurikhwan in any case you will need to either recompile the kernel or install a new one.
Else then what the result I can try to help you but I need to know what development packages have you installed?
I will try to see if I am managing to build it here with an elrepo lt or ml kernel.

@hariesnurikhwan it seems that from an unkown reason(to me) probably the compiler doesn't find that the system works with LITTLE_ENDIAN.
The basic test to verify the ENDIANESS of the system would be something like:

python -c "import sys;sys.exit(0 if sys.byteorder=='big' else 1)"; if [ "$?" -eq 0 ];then echo "BIG";else; echo "LITTLE";fi

Probably someone else can fix the issue in the sources.
I created a patch that allows it to be built on a Docker container but I cannot test it now on a running server.
Patch: https://gist.github.com/elico/eb6f4116cafd0e526f6506cb56166a93#file-little-endian-patch-patch

Details of the Dockerfile and build files at:

I have Built it on elrepo ml kernel and it compiles fine.

@elico Thanks for posting the resources.

OS - CentOS release 6.3 (Final)
Kernel - 4.2.8

Applied the patch given by @elico.

Has anyone got it working on CentOS 6.x ?

[elico]

@tinkerofthoughts There is a big diffrence between building\compiling to running it.
I will try to spin a CentOS 6 VM and see if I can reproduce it.
Can you attach here the specific commands from on a vanilla 6.latest?

• DVD-ISO inserted
• boot steps
• Installtion GUI steps
• yum commands
• other commands

That will help to try and reproduce the issue locally and mabe fix it(if posssible).
