NAME
nccgen - source code analysis
SYNOPSIS
nccgen file.c
DESCRIPTION
nccgen is a program that can help you hack/study the source code of C
programs. 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 nccgen 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 = nccgen
-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
nccgen will produce a file with nccout extension for every C file
analysed. 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.
