任何想法如何解決LNK2019 - 無法解析的外部符號，錯誤？

Question

我有這個惱人的錯誤，並沒有線索如何解決這個問題;我正在使用Visual Studio 2015，社區版本。

我正在製作一個C/C++控制檯應用程序，該應用程序附加到GTA5.exe並使用地址修改健康狀況。

這是錯誤：

Error LNK2019 unresolved external symbol _main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ) GTAConsole

GTAConsole.cpp代碼：

Sleep(1); 
} 

如果有人可以幫助，那簡直是真棒！

改變線INT Main() 通過main()
