NAME
ncc - source code analysis
SYNOPSIS
ncc file.c
DESCRIPTION
ncc is a program that can help you hack/study the source code of C pro‐
grams. It will report which functions call which other functions,
which functions are called by other functions and what global variables
and members of structures are used by functions. This is useful if you
want to analyse a program and eventually hack it.
USAGE
To use ncc find the Makefile of the program you want to analyse. In the
Makefile locate the line which sets the C compiler. That is usually
something like CC = gcc and you must change it to CC = ncc -ncgcc -ncld
-ncfabs. Then compile the application. It may be useful to also
replace AR = ar with AR = nccar and LD = ld with LD = nccld to link
nccout object files.
OUTPUT
ncc will produce a file with nccout extension for every C file ana‐
lysed. Then you can use the viewer nccnav (with nccnav program.nccout
) to view this data and do your work. If the procedure of make links
object files with "ar" or "ld" you should manually link the produced
.nccout files.
