Re: #define xxx #define yyy 123



You can't do this in the preprocessor alone. You can cause multiple passes using a Makefile with intermediate target rules, if you absolutely must, but it's highly discouraged unless you are entering an obfuscated C contest.

How do you get a define to be allowed within a define....

#define xxx #define yyy 123


More specifically, what I'm trying to do is this:

#define begin_enumerations #pragma options enum=4


But the compiler gives me the following error:

error: '#' is not followed by a macro parameter


It's interesting though.. I get the following error on the line where I use begin_enumerations:


error: syntax error at '#' token

... as if the #pragma options enum=4 actually made it down there to that line.


Is there some way to force the preprocessor to make a second pass?
