About extract call graph from C source code

I have try to use cscope and write some perl script for it .
but final I find If there are have the function piont call or function

I have try to use cscope and write some perl script for it.
There's now a KDE GUI for cscope, called kscope, which has a calltree
extractor based on cscope ouput. You may want to use that, instead of
rolling your own. It's at http://kscope.sourceforge.net/
but final I find If there are have the function piont call or function
defined by macro, cscope have some problem to parse the source code.
Indeed, use of function pointers does throw cscope off track quite
reliably ;-(. The problem can be reduced considerably by always using
typedefs for function pointer types, to avoid extra parentheses inside
the parentheses of a function definition, i.e. you should have

typedef int (*t_fp)(char);
void somefunction(t_fp function_pointer_argument);

instead of

void somefunction (int (*function_pointer_argument)(char));

You'll still get an incomplete call graph, though, since use of
function pointers generally makes static analysis impossible. cscope
won't log passing of a function foo() as an argument to function bar()
as a call to foo().

I'm not sure I understand what you mean by "function defined by
macro". Cscope does not run its input through the C preprocessor, so
it can't expand macros. If your function definition is entirely
hidden inside a macro call like the "DEFUN" convention in Emacs source
code, that means cscope's parser won't catch it. You'ld have to
extend cscope's parser yourself to do that, and I'm not even sure it
can be done inside the given framework.
Are there have another reliable ways or tools to extract call graph

sorry , since I don't know which group suit for this question,I just
post this question at these group. (linewrap adjusted) (snip cscope question>

now I have a problem about the extract call graph from statice C source code
, not from binary. .....
