   Linker error using Dev-C++
  Hello i'm having a problem compiling a simple application.i get this error messages when trying to compile the source code.[Linker error] undefined reference to 'WinMain@16'iD returned 1 exit statusWhat is it that i'm doing wrong? Thank you.Here is the setupfile: ac.cpp#include <iostream>using std::cout;using std::cin;using std::endl;#include "account.h"int main(){Account ac1(200), ac2(300);int a;cout<<"ac1: "<<ac1.getBalance()<<endl<<"ac2: "<<ac2.getBalance()<<endl;cin>>a;return 0;}file: account.hclass Account{public: Account(int); void credit(int);  void debit(int);  int getBalance();    private:int accountBalance;};file: account.cpp#include <iostream>using std::cout;using std::cin;using std::endl;#include "account.h"Account::Account(int balance){accountBalance = balance;if(accountBalance < 0){accountBalance = 0;cout<<"incorect balance input. Balance was initiated at "<<accountBalance<<endl;}} void Account::credit(int balToAdd){if(balToAdd >= 0)accountBalance += balToAdd;else cout<<"Nothing was added."<<endl;}void Account::debit(int balToSubstract){int newBal = accountBalance - balToSubstract;if(balToSubstract >= 0 && newBal >= 0)accountBalance = newBal;else cout<<"Nothing was substracted."<<endl;}int Account::getBalance(){return accountBalance;}
  You need to compile as a console application (GUI applications use WinMain instead of main). However, while you are at it, consider moving to a new IDE - Dev-C++ is hopelessly outdated.   ;  I'll just throw in a bit on the switch to a new development environment:I used to be a Dev C++ user, and I was that way for years. Just recently, I moved to a Vista 64 bit OS to accomidate 4 gigs of RAM, and Dev C++ would not work with it. I finally decided to make the jump to VC++ 2005 Express, and it was the best thing I ever did, IDE wise. I used to have problems getting the Platform SDK with all the include files going properly, but this time, it worked perfectly. Go over to VC++ Express  and download it. This will be enough to work with Console programs, but when you move on to needing more include files, find the Platform SDK. For some reason, I am having problems finding it (No coffee yet this morning), so simply do a google search for "Platform SDK" and it should be one of the first links. It will be on the microsoft site. Good luck!   ;  The reason why i don't use vc++ 1. really i don't like ms products. 2. I feel that using vc++ will get me into a bad habbit into learing c++ for win only, while my objective is create code as portable as possible.Keep in mind i just started getting serious with C++ so any suggestion for IDE as well as my paranoias above are welcome :)   ;Quote:Original post by AluminX1. really i don't like ms products.Not sure what to do with that. It's like saying "I don't like yellow things". What's your problem with Minesweeper?Quote:2. I feel that using vc++ will get me into a bad habbit into learing c++ for win only, while my objective is create code as portable as possible.That's not really an issue for IDEs. It's more of a libraries thing.   ;Quote:Original post by AluminXThe reason why i don't use vc++ 1. really i don't like ms products. 2.

And you're being foolish to think that merely using Visual C++ will get you into the bad habit of learning c++ for windows only. You can write standard compliant code in Visual C++. Unless you specifically look for the non-standard extensions or choose to program with Microsoft's included libraries you have nothing to fear.If that still doesn't sway you you should still avoid Dev-CPP and use the IDE Code::Blocks. It is quite capable to develop in and much better than what you're using now.   ;Quote:Original post by SneftelThat's not really an issue for IDEs.

It's more of a libraries thing.I thought that was a compiler thing no?No.There are certainly things that need to be taken into consideration when moving from compiler to compiler, such as non-standard language extensions and differences in how the compiler coforms to (or doesn't conform to) the C++ standard. But these sorts of issues are more or less unavoidable (especially given the complexity of the C++ language), and there are almost always ways to work around them.In short, using Visual Studio will in no way tie you to writing Windows-specific code. (I and many others here develop cross-platform applications using Visual Studio for Windows, and other IDEs/compilers for other platforms, without any difficulties.)   ;  Practically, it is probably a good idea to set your VC++ to strict standards compliance, and plug in a different vendor's compiler (also on strict standards compliance mode), if you want to avoid learning VC++isms.That (the standards-extensions and bugs in VC++), and the fact that VC++ has a proprietary "makefile" system, and the editor isn't a "real editor" (heh), etc -- are about the only problems with learning to code using VC++.;  This is great.Well thank you to everyone. I didn't think i would get some much help and insight from that simple error message :)Thank you!
