Precompiled header error
-
I get the error listed at the bottom when I try compiling a source file which absolutely has no syntax errors. This has something to do with the precompiled header. I just learnt that precompiled headers are used for performance to speed up the compilation. If a header file is used in many different source files, precompiled header (.pch) file will be created the first time this header file is compiled and the next time this header file is called in a differnt source file, it will stop compiling and directly use the .pch file. Knowing that, what relationshop does precompiled header have with stdafx.h. Why are stdafx.h used for? When I tried creating a project in Visual Studio 2005, stdafx.h and stdafx.cpp were automatically created. Can someone explain what is going on here please...... :confused: Thanks, Jaysan BUILD LOG

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========When using precompiled headers, anything that comes before
#include "stdafx.h"is considered a comment. The file doesn't have to be named "stdafx.h", but if you create your project using the wizard, it will be. Stdafx.h is where you add common header files to gain this compilation optimization. Make sure that the first#includeis "stdafx.h".If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week Zac

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========When the compiler is processing a CPP file (other than stdafx.cpp) it looks for the line
#include "stdafx.h"and at that point, loads the saved state from the PCH file. (This is, btw, why anything you write before that include gets ignored.) If for some reason you can't include stdafx.h but want that CPP file to use the PCH, you can use#pragma hdrstop--Mike-- Visual C++ MVP :cool: LINKS~!

Are #include "stdafx.h" standard in the sense that you don't have to modify anything in the file after its created for you when you create a new project in Visual Studio 2005?

Yes. If your project settings say that you are using precompiled headers, but you don't include stdafx.h, you will get that error.
