问题描述
这很难解释...而且很长.
我有很多课程，其中两个相关的课程是:对象和AI
在Object类方法中，我使用定义将注释块放置在代码中以用于测试工具.
This is very hard to explain... and long.
I have a lot of classes the two relevant ones in this are: Object and AI
In the Object class methods I used definitions to place comment blocks inside my code for my test harness.
#ifndef TEST
#define TEST
#endif
#ifdef TEST
#include <iostream>
using namespace std;
#endif
然后在我的代码中，我可以使用:
then inside my code i can use:
#ifdef TEST
cout << "some output" << endl;
#endif
想法是，只要我需要运行测试，就可以轻松地注释/取消注释#define TEST.注释时，编译器将忽略所有输出.
效果很好.
直到我使用相同的想法制作了用于AI的测试工具.我注释掉了对象定义，但仍然出现对象输出.
因此，我认为TEST定义是从AI携带到对象中的，因此我对其进行了更改，使对象定义为TEST_OBJECT，而AI定义为TEST_AI，并且仍然发生对象输出.我注释掉了所有对象输出，并且仍然发生了输出.我删除了整个项目，并使用相同的cpp和h文件创建了一个新项目，但它仍然发生.
因此，简单的问题是:这到底是怎么回事?即使我看到它正在编译，也好像没有在编译对象.
有想法吗?
The idea being that if i can easily comment/uncomment #define TEST whenever i need to run a test. When it is commented all the outputs will be ignored by the compiler.
It worked great.
Until I made the test harness for AI using the same idea. I commented out the Object definition but the Object outputs still occurred.
So I figured the TEST definition was being carried from AI into object so I changed it so the object definition was TEST_OBJECT and the AI definition was TEST_AI and the Object output still occurred. I commented out all the Object outputs and the output still occurred. I deleted the entire project and created a new project using same cpp and h files and it still occurred.
So the simple question is: why the hell is this happening?! It''s like Object is not being compiled even though I can see it compiling.
Thoughts?
推荐答案
#ifndef TEST
#define TEST
#endif
在Visual Studio的相应属性表中，在项目级别定义预处理程序常量"TEST".我建议在一个中央属性表中对其进行定义，您将在每个项目中引用该属性表.
Define the preprocessor constant "TEST" at project level, in the resepective property sheets of Visual studio. I recommend to define it in a central property sheet which you will reference from each project.
