问题描述

我正在学习一本名为:DirectX 11 的 3D 游戏编程简介

I am following an example book called: Introduction to 3D Game Programming with DirectX 11

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

It is all written in VS2010. I would like to try using VS2013... It is an example project for Windows Desktop Program

我有一个包含以下内容的程序(包括一些其他常用文件):

I have a program with the following in it (including some other files as part of common use):

当我去编译它时，它抛出错误:

When I goto compile it it throws the error:

FXC : error X3501: 'main': entrypoint not found

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，我是否还必须将其设置为着色器 5?

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?

我尝试了以下文章的变体:http://social.msdn.microsoft.com/Forums/windowsapps/en-US/51859322-fc36-4946-b4cb-b5971fcaa9e5/fxc-error-x3501-main-entrypoint-not-found?forum=wingameswithdirectx 但就是无法运行.

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=wingameswithdirectx but just can't get it to run.
