使用“#ifdef”时，Visual Studio 错误地标记非活动代码块
我的项目有一堆#ifdefs。这些#ifdef 使用的宏通常使用'/D' 选项通过命令行传递，以获得不同的构建配置。 Visual Studio 错误地假设这些宏未定义，并将这些 #ifdef 内的代码块灰显。问题不在于语法突出显示 - 我可以从选项将灰色代码转换为彩色代码；主要问题是我无法访问该 #ifdef 中存在的任何函数的函数定义。我尝试阅读有关 Visual Studio 提示文件 的内容，但这对我。
谁能帮我解决这个问题吗？我使用的是 Visual Studio 2008。
My project has a bunch of #ifdefs. The macros used by these #ifdefs are usually passed through the command line using the '/D' option to get different build configurations. Visual studio incorrectly assumes that these macros are not defined and greys out the code blocks present inside these #ifdefs. The problem is not syntax highlighting - I can turn the grayed out code to colored code from Options; the main issue is that I am not able to go to the function definition of any functions present inside that #ifdef. I tried reading about Visual Studio hint files but that didn't work for me.
Can anyone help me with this issue? I am using Visual Studio 2008.

您是否在 VS 中将多种构建定义为“调试”、“发布”等配置，还是使用 makefile 进行构建？如果你还没有教过 VS 关于你的 /D 选项，那么我想它对你没有帮助。但是您应该能够在项目属性（配置属性、C/C++、预处理器）下设置预处理器定义以获得您想要的效果，对吧？
对于传递给编译器的每个选项
/DMACRO=XXX，请在 IntelliSense 预处理器定义中指定MACRO=XXX。对于传递给编译器的每个选项/DMACRO（无值），请在 IntelliSense 预处理器定义中指定MACRO。Did you define several kinds of builds within VS as Configurations like Debug, Release, or are you building with makefiles? If you haven't taught VS about your /D options then I guess it can't help you. But you should be able to set up Preprocessor Definitions under project properties (Configuration Properties, C/C++, Preprocessor) to get the effect you want, right?
For each option
/DMACRO=XXXthat you pass to the compiler, specifyMACRO=XXXin the IntelliSense Preprocessor Definitions. For each option/DMACRO(no value) that you pass to the compiler, specifyMACROin the IntelliSense preprocessor definitions.如果您不进行调试，而只是尝试获得智能感知或其他响应，那么您始终可以快速输入
#define来强制 IDE 正常运行。看来你和这个家伙有类似的问题：
可以在 VS2008 中的预处理器指令块（例如 #ifndef ... #endif）中启用智能感知吗？
If you're not debugging, and you're just trying to get intellisense or whatever to react, you can always just throw up a quick
#defineto force the IDE to behave.Seems you have a similar problem as this fellow:
Can intellisense be enabled in VS2008 within preprocessor directive blocks like #ifndef ... #endif
