I am trying to create an "all inclusive" header so i only need to type #include "all.h" at the beginning of a program As I am still learning, i only have three things in all.h atm which include: ifndef ALL_H define ALL_H #include <iostream> #include "stdafx.h" #include <cstdlib> endif and in my main project i have: #include "all.h" int main() { //code } but when i try to compile the program i get this error: d:\c++ projects\helloworld\helloworld\helloworld.cpp(1) : warning C4627: '#include "all.h"': skipped when looking for precompiled header use Add directive to 'stdafx.h' or rebuild precompiled header d:\c++ projects\helloworld\helloworld\helloworld.cpp(12) : fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source? it is a short file... and line 12 would be directly after the } ending the main() but nothing is there. So, I am asking if I have my header setup right, and is it even possible to do what I am trying to do?
