I have an implementation file, a header, and a main cpp file. I have a class defined in the header, which I will simplify to the basics for viewing audiences: class SomeClass { public: SomeClass(); //constructor }; ...with function members defined in the implementation: SomeClass::SomeClass() { cout << "hellon"; } Trouble is, PB complains that I've already defined SomeClass elsewhere. It doesn't *show* me where, though. I've tried this in CodeWarrior too, with similar complaints. Now I'm thinking it's my fault and not a compiler quirk. But I essentially copied the above out of my textbook! Any thoughts? Thanks.

I have no idea what PB is, but what I am sure about is that you need to post a minimal, compilable code what shows your problem. With this information we could only guess. http://www.parashift.com/c++-faq-lite/how-to-post.html#faq-5.8 -- Attila aka WW Back to top Howard Guest Posted: Tue Sep 30, 2003 4:11 pm    Post subject: Re: Implementation Files & C++ Quote: Normally I use PB for Cocoa, but now I'm using it for a school project.

If so, you can fix that by putting the following lines (or something similar) around the contents of your header file: #ifndef h_myclass #define h_myclass // rest of header file contents here... #endif -Howard Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
