C++ Fatal Error LNK1120: 1 unresolved externals

My problem was int Main() instead of int main()

good luck

From msdn

When you created the project, you made the wrong choice of application type. When asked whether your project was a console application or a windows application or a DLL or a static library, you made the wrong chose windows application (wrong choice).

Go back, start over again, go to File -> New -> Project -> Win32 Console Application -> name your app -> click next -> click application settings.

For the application type, make sure Console Application is selected (this step is the vital step).

The main for a windows application is called WinMain, for a DLL is called DllMain, for a .NET application is called Main(cli::array ^), and a static library doesn't have a main. Only in a console app is main called main

I incurred this error once.

It turns out I had named my program ProgramMame.ccp instead of ProgramName.cpp

easy to do ...

Hope this may help

Well it seems that you are missing a reference to some library. I had the similar error solved it by adding a reference to the #pragma comment(lib, "windowscodecs.lib")
