Sounds like you're including the same header twice in the same module, usually done by #including headers inside other headers (which I tend to avoid unless it /really/ makes sense to do it), but it all comes down to a question of style (now donning anti-flame underwear...) In any case, I use the following lines in EVERY header, regardless... for example, for include file foo.h #ifndef __FOO_H__ #define __FOO_H__ (body of include file goes here) #endif That way, you won't get these problems... but of course it allows you to get lazy... -- | Mark McDougall | | Technetium Development Pty Ltd | "Electrical Engineers do it | msmcdoug AT zeta DOT org DOT au | with less resistance!" | http://www.zeta.org.au/~msmcdoug |
