PRB: Link Error LNK2001: Unresolved External Symbol _main (291952)

RESOLUTION

• If you have created a Win32 console application instead of a Win32 application by mistake, there are two ways to fix this problem:
  • From the Project menu, choose Settings, click the C/C++ tab, and change preprocessor definitions from WIN32, _DEBUG, _CONSOLE, and _MBCS to WIN32, _DEBUG, and _WINDOWS. Next, click the Link tab, and under Project Options, change /subsystem:console to /subsystem:windows. -or-
    
    
  • Create a new project and select Win32 Application instead of Win32 Console Application. Add the files to that project.
• If you have created a Win32 console application and forgot to provide a main function, write a main function in one of the source files added to the project.
• If you have selected main as the custom entry point by mistake, from the Project menu, choose Settings and click the Linker tab. Select output as the category and remove main from the entry-point symbol text box.
• If your project is an ATL project, there are two ways to fix the problem:
  • Remove _ATL_MIN_CRT from the list of preprocessor definitions to allow CRT startup code to be included: From the Build menu, choose Settings. Hold down the CTRL key while selecting all of the release configurations. On the C/C++ tab, choose the General category, and then remove _ATL_MIN_CRT from the preprocessor definitions edit box. -or-
    
    
  • If possible, remove calls to CRT functions that require CRT startup code and use their Win32 equivalents. For example, use lstrcmp instead of strcmp. Known functions that require CRT startup code include the string and floating point functions.
