错误C4439“主要" [英] Error C4439 'main'

问题描述

大家好，

我是VC ++的新手，这是我的第一个独立项目，请原谅我的无知！

我的项目可以在Debug模式下编译并运行良好.

但是，当我尝试在发布模式下编译它时(我需要使用它来使用安装向导进行应用程序部署)，我得到以下错误:

错误C4439:"main":签名中具有托管类型的函数定义必须具有__clrcall调用约定

我正在使用以下参数:

呼叫约定:_stdcall(/Gz)
公共语言运行时支持(/clr)
运行时库:多线程DLL(/MD)
我还在项目属性的其他依赖项"中添加了库文件ole32.lib.

当我尝试使用:

int __clrcall main(array<System::String ^> ^args)

我收到以下链接错误:

Hi All,

I am a newbie to VC++ and this is my first independent project so please pardon my ignorance!!

My project compiles and runs perfectly fine in Debug mode.

However, when I try to compile it in Release mode ( I need this to use the Setup wizard for application Deployment) I get the following error:

error C4439: ''main'' : function definition with a managed type in the signature must have a __clrcall calling convention

I am using the following parameters:

Calling Convention : _stdcall (/Gz)
Common Language Runtime Support (/clr)
Runtime Library: Multi-threaded DLL (/MD)
I have also added the library file ole32.lib in the Additional Dependancies in the Project Property.

When I try to use :

int __clrcall main(array<System::String ^> ^args)

I get the following Link errors:
