=== Output of "frama-c -version" ===

Version: Carbon-20110201
Compilation date: Thu Jul 14 18:45:04 UTC 2011
Share path: /usr/share/frama-c (may be overridden with FRAMAC_SHARE variable)
Library path: /usr/lib64/frama-c (may be overridden with FRAMAC_LIB variable)
Plug-in paths: /usr/lib64/frama-c/plugins (may be overridden with
FRAMAC_PLUGIN variable)

=== END ===

I was able to use -cg to generate the .dot file for a simple hello.c
file. Is there any way to tell frama-c or gcc to ignore any header
file inclusion in the sources when doing static analysis?

I am only interested in the call graph, and if I move the source files
to a different directory or build environment where the headers don't
exist, I get an error like:

=== Error ===

cg] beginning analysis
[kernel] preprocessing with "gcc -C -E -I.  omega.c"
omega.c:34:20: fatal error: config.h: No such file or directory
compilation terminated.
[kernel] user error: failed to run: gcc -C -E -I.  -o
'/tmp/omega.ce9509e.i' 'omega.c'
                     you may set the CPP environment variable to
select the proper preprocessor command or use the option
"-cpp-command".
[kernel] user error: skipping file "omega.c" that has errors.
[kernel] Frama-C aborted because of invalid user input.

=== END ===

I tried using gcc -x option with 'cpp-output':

  $ gcc -x cpp-output file.c

But, I get the "error: stray '#' in program" errors.

Thanks for your replies.

SK
