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.

NAME

     mkdep -- construct Makefile dependency list

SYNOPSIS

     mkdep [-ap] [-f file] [flags] file ...

DESCRIPTION

     The mkdep utility takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file
     dependencies which are written into the file ``.depend''.	An example of its use in a Makefile might be:

	   CFLAGS= -O -I../include
	   SRCS= file1.c file2.c

	   depend:
		   mkdep ${CFLAGS} ${SRCS}

     where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler.

     The user has the ability to change the preprocessor and preprocessor options used.  For instance, to use gcc as the preprocessor and to
     ignore system headers, one would use

	   depend:
		   env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep 
			   ${CFLAGS} ${SRCS}

     The options are as follows:

     -a      Append to the output file, so that multiple mkdep's may be run from a single Makefile.

     -f      Write the include file dependencies to file, instead of the default ``.depend''.

     -p      Cause mkdep to produce dependencies of the form:

		   program: program.c

	     so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module.  This is useful
	     for programs whose source is contained in a single module.

ENVIRONMENT

     CC 	     Specifies the C compiler to use.  The specified compiler is expected to have options consistent with the GNU C compiler.

     MKDEP_CPP	     Specifies the preprocessor to use.  The default is "${CC} -E".

     MKDEP_CPP_OPTS  Specifies the non-CFLAGS options for the preprocessor.  The default is "-M".

FILES

     .depend  File containing list of dependencies.

HISTORY

     The mkdep command appeared in 4.3BSD-Tahoe.
