c++ - 无法在 Visual Studio Community 2015 中编译基本程序(LNK2019 - MSVCRTD.lib)

Question

我在从未安装过任何 IDE/开发工具的全新 Win10 安装上安装了 Visual Studio Community 2015。

我创建了一个空的c++项目，添加了main.cpp，将入口点设置为main并添加了:

void main()
{

}

在 VS2013 上我可以毫无问题地做到这一点。我遇到了我无法弄清楚的链接器错误:

更新:

我更改了两个配置属性:

• 链接器> 输入> 忽略所有默认库> 是(/NODEFAULTLIB)
• C/C++> 代码生成> 基本运行时检查> 默认

这让我构建了上面的代码，但是在添加了一些其他琐碎的代码之后，我遇到了很多其他问题:

#include <string>

using namespace std;

void main()
{
    string blah = "string";
}

包含一个标准库应该是微不足道的，但是:

Answer 1

好吧，我明白了，但这引出了另一个问题。

问题是 我在 Linker 中定义 /ENTRY:Main > Advanced> 入口点 除了入口点是Main 而不是main。

所有路径/库都井井有条，令人惊讶。我撤消了问题中“更新:”行下提到的配置更改 - 这不是问题所在。 p>

真正奇怪的是，我绝对可以在 Visual Studio 2013(我从中迁移了项目)中完全按照上述方式进行操作。也许更奇怪.. 我还有另一个项目，我也以同样的方式迁移了 also 将 Main 明确声明为入口点，但它没有收到链接器的投诉.
