确保 VS 2008 将我的项目视为 C++而不是 C++/CLI
我正在使用本机 C++ 在 Visual Studio 2008 中工作。
一位同事编写了一个库，并将其中一个类命名为interface。这是一个构造函数：
template <typename DtedInterface>
interface<DtedInterface>::interface (
std::string const& tleFile,
std::string const& dtedDir,
dted::DtedLevel const& dtedLevel,
double sw_latitude,
double sw_longitude,
unsigned int rows,
unsigned int columns )
: m_impl ( new interface_impl<DtedInterface> ( theFile, dtedDir, dtedLevel, sw_latitude, sw_longitude, rows, columns ) )
{}
令我担心的是 Visual Studio 2008 突出显示了 interface 一词作为关键字； interface 是 C++/CLI 中的关键字，但不是 C++ 中的关键字。这看起来不像是有效的 C++/CLI，但对于本机 C++ 来说没问题。
看起来编译得很好，但如何确保 Visual Studio 将其解释为 C++ 而不是 C++/CLI？在某种程度上，VS 似乎将其视为 C++/CLI。它只是一个关键字突出显示设置吗？
I'm working in Visual Studio 2008 with native C++.
A colleague wrote a library, and he named one of his classes interface. Here's a constructor:
template <typename DtedInterface>
interface<DtedInterface>::interface (
std::string const& tleFile,
std::string const& dtedDir,
dted::DtedLevel const& dtedLevel,
double sw_latitude,
double sw_longitude,
unsigned int rows,
unsigned int columns )
: m_impl ( new interface_impl<DtedInterface> ( theFile, dtedDir, dtedLevel, sw_latitude, sw_longitude, rows, columns ) )
{}
What concerns me is that Visual Studio 2008 is highlighting the word interface as a keyword; interface is a keyword within C++/CLI but not C++. This doesn't look like it would be valid C++/CLI, but it's fine for native C++.
Things look like they compile fine, but how do I make sure that Visual Studio is interpreting this as C++ rather than C++/CLI? At some level, it appears that VS views this as C++/CLI. Is it just a keyword highlighting setting?

Visual Studio IDE 和 Visual C++ 编译器是两个独立的实体。具体来说，它们是作为单独进程运行的两个单独的可执行文件（用于 IDE 的 devenv.exe 和用于编译器的 cl.exe）。 IDE 只是生成 cl.exe 进程来执行实际的编译。
IDE 在某处有一个关键字列表，它只是告诉文本编辑器要突出显示哪些单词。它并不是超级复杂；不一定是这样。编译器拥有最终决定权，而不是语法荧光笔（或智能感知）。
只要
/clr开关如果不传递给 cl.exe 进程，编译器会将代码编译为本机 C++（这是默认设置）。 IDE 只需输入源代码的文件路径，编译器就会作为命令行参数切换到 cl.exe 进程。语法突出显示与编译器如何解释代码无关。The Visual Studio IDE and the Visual C++ compiler are two separate entities. Specifically, they are two separate executables (
devenv.exefor the IDE andcl.exefor the compiler) that run as separate processes. The IDE simply spawns thecl.exeprocess to perform the actual compilation.The IDE has a list of keywords somewhere that simply tells the text editor which words to highlight. It isn't super sophisticated; it doesn't have to be. The compiler has the final say, not the syntax highlighter (or Intellisense for that matter).
As long as the
/clrswitch is not being passed to thecl.exeprocess, the compiler will compile the code as native C++ (which is the default setting). The IDE simply feeds in the file paths of your source code and the compiler switches as command-line arguments to thecl.exeprocess. The syntax highlighting has no bearing on how the compiler interprets the code.如果您使用的是 C++/CLI，代码将拒绝编译，因此只要您按下“build”并且它可以工作，那么您就知道您处于本机环境中。还有用于 CLR 构建的预定义宏。
The code will refuse to compile if you're in C++/CLI, so as long as you push "build" and it works, then you know you're in native. There are also pre-defined macros for CLR builds.
如果您确实需要验证它没有编译托管 C++，请查看项目属性并检查“配置属性”->“常规”下的“公共语言运行时支持”设置。对于“配置属性”->“C/C++”->“常规”下的每个文件的属性，检查“使用公共语言运行时支持进行编译”设置。如果所有这些都设置为“无公共语言运行时支持”，则该项目不是托管 C++。
If you're really need to verify it's not compiling managed C++, look at the project properties and check the "Common Language Runtime support" setting under the Configuration Properties->General. As well for each file's properties under Configuration Properties->C/C++->General check the "Compile with Common Language Runtime support" setting. If all of those are set to "No Common Language Runtime support", the project is not managed C++.
