I'd like to understand how to use a tool called NCC: http://students.ceid.upatras.gr/~sxanth/ncc/

Its purpose is to detail program call graph and internal symbol dependencies, similar to cflow/cscope. But I can't get it to work.

I've cloned a git repo of tcpdump project and edited Makefile CC to point to nccgen -ncgcc -ncld -ncfabs instead of CC = gcc

Here's the output:

make[1]: Entering directory `/home/rostamn739/Software/tcpdump'

make[1]: Nothing to be done for `all'.

make[1]: Leaving directory `/home/rostamn739/Software/tcpdump'

No .nccout files have been produced

    Have you tested with other projects than tcpdump? Do you get the expected result if you run ncc on a simple hello world file? – hlovdal Dec 17 '12 at 12:08
