nccgen - source code analysis
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.
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.
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.
