omnicpp man page

omnicpp — OmniORB cpp preprocessor for IDL compiler


omnicpp [options]


This manual page documents briefly the omnicpp command.

omniidl is omniORBs IDL compiler and uses omnicpp as it's C preprocessor.  omnicpp is really just the GNU C preprocessor under a different name.  Normally you should not need to invoke this directly but should use omniidl instead.


As this is just the GNU C preprocessor cpp you can see that program for the full options.  Normally you should not be invoking this directly but should use omniidl instead.  The options listed here should really be given to omniidl, but they are passed straight to omnicpp.

-D name

Define name for the preprocessor.

-U name

Undefine name for the preprocessor.

-I dir

Include dir in the preprocessor search path.  Note that the current directory is not on the include search path by default.  Use -I. for that.

The programs are documented fully by the HTML documentation in the omniorb4-doc package.
