代码的编译过程如图所示: When the preprocessor processes the#include "add.h"line, it copies the contents of add.h into the current file at that point. Because ouradd.hcontains a forward declaration for functionadd, that forward declaration will be copied intomain.cpp. The end result is a pr...

Bug Summary: When I#include <stdarg.h>in a header file likemy_file.h, it gives an error when building the projectfatal error: 'stdarg.h' file not found. But when I move the include to a .cpp file likemy_file.cppit suddenly goes away and compiles/builds fine. If I build outside...

I've never really understood why C++ needs a separate header file with the same functions as in the .cpp file. It makes creating classes and refactoring them very difficult, and it adds unnecessary files to the project. And then there is the problem with having to include header files, but...
When you use the global include opencv.hpp (which is some kind of umbrella since it includes all the others), all the library header files are included and thus copied into your .cpp file. This means less typing for you but in the end a bigger file for the compiler. Hence, compilation...
