Short answer: yes, you'll need to use some tricks with #define to do what you want; values set in an enum aren't recognised by the preprocessor.

An enum is interpreted by the compiler and not the preprocessor. The statement is ignored by the preprocessor and thus something like PIN_A is not any more meaningful, as far as the preprocessor is concerned, in the later code than j would be from a statement like:

Code:
int j = 23;

NAME
omnicpp - OmniORB cpp preprocessor for IDL compiler SYNOPSIS
omnicpp [options] DESCRIPTION
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. OPTIONS
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. SEE ALSO
omniidl(1). The programs are documented fully by the HTML documentation in the omniorb4-doc package. AUTHOR
