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.
