Need help with loading kernel with modules

Hi,

I am trying to upgrade an x86 target board with lng-x86-64-3.14 pre-built, but I am not able to get the modules installed into the kernel. I need the /lib/modules/3.14.... to run a open traffic generator on it. Fallowing is the error I get when I do "make",

make -C /lib/modules/3.14.44/build M=/home/trex/trex-core/scripts/ko/src modules make[1]: *** /lib/modules/3.14.44/build: No such file or directory. Stop.

I am attaching my Json script, please let me know if I am missing something.
