Compile on Centos 6.x?

[hariesnurikhwan]

Hello, is it possible to compile the ndpi-netfilter to make it work on Centos 6.x? I've look around but haven't found anything to make it work on Centos 6.x

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

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

@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: https://gist.github.com/elico/eb6f4116cafd0e526f6506cb56166a93

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).
