Precompiled header? - Developers

Does anyone ever use it? I personally have just been deleting it and forgetting it but recently I have been wanting to mess around with it. Is it good to use or no? I am a windows programmer so none of this portability crap please.

no

Precompiled headers? I didn't know you could compile a header.

Basically you use a PCH when you have several large header files that change very infrequently. It speeds up compilation time. The PCH is included in every file of your project, AFAIK. So yes, people do use them. They're good if you use them for what they're intended for. Google ("g++ precompiled header use") will tell you how they work a lot more than I can.

[QUOTE=PvtCupcakes;16103775]Precompiled headers? I didn't know you could compile a header.[/QUOTE] gcc does it.

They are incredibly useful if you have a large header or a series of headers that you want to include in every file in a project.

[QUOTE=Kylegar;16107973]They are incredibly useful if you have a large header or a series of headers that you want to include in every file in a project.[/QUOTE] Also provided they're relatively static. If they get updated a lot you pretty much loose all benefit.

The bit about being included into every file. That's a "Prefix Header". Although they are usually pre-compiled also.
