cxref-cpp

cxref-cpp(1)						      General Commands Manual						      cxref-cpp(1)

NAME

       cxref-cpp - A modified C preprocessor to use with cxref.

SYNOPSIS

       cxref-cpp ...

DESCRIPTION

       To  improve  the  output  that  is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
       (named cxref-cpp).

       This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler.	In
       a  standard  preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
       not important.

       With cxref-cpp, there are some features that are different to the standard GNU CPP:

	      Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include  lines  from  the  source
	      file.  In version 2.8.0 and later this option is present.

	      Comments	trailing  a  #include  or  a  #define are not preserved by all versions of gcc even if the -C option is used.  This is not
	      important while compiling, but is useful for documenting.

	      The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed.  This
	      means  that it includes the same default include directory paths and macro definitions.  The file that contains these definitions is
	      called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by  the  -cxref-cpp-defines  command  line
	      option.

OPTIONS

       The same as for gcc, apart from '-cxref-cpp-defines' described above.
