Currently I'm having issues with WinMain
in C (specifically in Visual Studio).
For instance...
#include <stdio.h>
#include <Windows.h>
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR lpCmdLine, INT nCmdShow)
{
return(0);
}
1>------ Build started: Project: GameB, Configuration: Debug x64 ------
1>LIBCMTD.lib(exe_main.obj) : error LNK2019: unresolved external symbol main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ)
1>E:\James\VisualStudio\CProjects\GameB\x64\Debug\GameB.exe : fatal error LNK1120: 1 unresolved externals
1>Done building project "GameB.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Just this basic set-up gives me an "inconsistent annotation for WinMain" warning. I have been searching for any help for 2 days and the the closest I come to an answer is people talking about WinMain in the context of C++. I have a feeling this is a problem with Visual Studio as I was originally just using VS Code and managed to get an app (one that generated a pop-up window) to compile and run.
You just set up your winmain wrong. This should work:
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow);
or
INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR lpCmdLine, INT nCmdShow)
{
return 0;
}
Don't forget to #include <Windows.h> and change subsystem to windows.
您需要在设置中将子系统从Console
设置为Windows
,方法是在解决方案资源管理器中右键单击您的项目,选择properties
,然后转到Linker->System
并将SubSystem
设置为Windows(/SUBSYSTEM:WINDOWS)
。
To use the WinMain
program entry point, you need to tell the linker to target the "Windows" subsystem, rather than building a console application. Otherwise, the linker will look for (and fail to find) the standard main
entry point for C programs.
In the Solution Explorer, right-click on your project and select "Properties". Then navigate to the "Linker -> System" page and select "Windows (/SUBSYSTEM:WINDOWS)" as the target:
On your "inconsistent annotation" warning, see this Q/A: Inconsistent annotation for 'WinMain'
Also, as noted in the answer by SNO , you should add the WINAPI
attribute to your WinMain
function.
