FXC : error X3501: 'main': entrypoint not found
提问by Jimmyt1988
I am following an example book called: Introduction to 3D Game Programming with DirectX 11
我正在阅读一本名为：Introduction to 3D Game Programming with DirectX 11的示例书
It is all written in VS2010. I would like to try using VS2013... It is an example project for Windows Desktop Program
都是用VS2010写的。我想尝试使用VS2013...它是Windows桌面程序的示例项目
I have a program with the following in it (including some other files as part of common use):

When I goto compile it it throws the error:
当我去编译它时，它会抛出错误：
FXC : error X3501: 'main': entrypoint not found
What is the entry point of my shader file from the examples? and how do I set that in the shader compiler properties? do I also have to set it to shader 5 considering it is mentioning vs_5_0 in the shader file?
示例中我的着色器文件的入口点是什么？以及如何在着色器编译器属性中设置它？考虑到它在着色器文件中提到 vs_5_0，我是否还必须将它设置为着色器 5？
I have tried a variation of the following article: http://social.msdn.microsoft.com/Forums/windowsapps/en-US/51859322-fc36-4946-b4cb-b5971fcaa9e5/fxc-error-x3501-main-entrypoint-not-found?forum=wingameswithdirectxbut just can't get it to run.

The option below only works on Visual Studio 2012 or later version.
以下选项仅适用于 Visual Studio 2012 或更高版本。
If you compile a .fx file, you can set the shader type to "fx" as below:
如果你编译一个 .fx 文件，你可以将着色器类型设置为“fx”，如下所示：
Right click your project in VS and select properties
Expand the HLSL compiler option, select "Effect(/fx)" for Shader Type, you can also specify a entry point function for Entrypoint Name.
在 VS 中右键单击您的项目并选择属性
展开HLSL编译器选项，Shader Type选择“Effect(/fx)”，也可以为Entrypoint Name指定一个入口点函数。

since VS2012microsoft decided to include a HLSL compiler (that's where the error comes from), but you don't need it since you are loading and compiling the .fx file at runtime using the D3DX11CompileFromFile() function. So just exclude the .fx file from the build, right-click on the file in the solution explorer and choose properties->configuration properties->general->excluded from build->yes.
由于VS2012微软决定包含一个 HLSL 编译器（这就是错误的来源），但您不需要它，因为您在运行时使用 D3DX11CompileFromFile() 函数加载和编译 .fx 文件。因此，只需从构建中排除 .fx 文件，在解决方案资源管理器中右键单击该文件，然后选择属性-> 配置属性-> 常规-> 从构建中排除-> 是。

I equally have been working with that book and using the samples in VS 2013 and ran into the same error, when I came across your question.
我同样一直在使用那本书并使用 VS 2013 中的示例，但在遇到您的问题时遇到了同样的错误。
In order to compile the samples you need to have the Project's Properties > Config. Properties > General > Platform Toolset to v100 (VS2010), so you won't see the HLSL Compiler options that zdd mentions in their answer because that comes with later versions of VS's toolset (e.g. having your Platform Toolset set to v120 (VS2013)).
为了编译示例，您需要拥有项目的属性 > 配置。属性 > 常规 > 平台工具集到 v100 (VS2010)，所以你不会看到 zdd 在他们的回答中提到的 HLSL 编译器选项，因为它带有更高版本的 VS 工具集（例如将你的平台工具集设置为 v120 (VS2013)） .
Using the v100 toolset you can still set up the build process, as outlined in 6.8.5 Compiling an Effect at Build Time (p. 221), which configures it as a custom build step.
使用 v100 工具集，您仍然可以设置构建过程，如 6.8.5 在构建时编译效果 (p. 221) 中所述，将其配置为自定义构建步骤。
