How do I turn on multi-CPU/Core C++ compiles in the Visual Studio IDE (2008)?
提问by dwj
I have a Visual Studio 2008 C++ project that has support for using multiple CPUs/cores when compiling. In the VCPROJ file I see this:
我有一个 Visual Studio 2008 C++ 项目，它支持在编译时使用多个 CPU/内核。在 VCPROJ 文件中，我看到了这个：
<Tool
Name="VCCLCompilerTool"
AdditionalOptions="/MP"
...
I can't find where that was turned added via the IDE and I want to set up another project that uses all of my cores during compilation.
我找不到通过 IDE 添加的位置，我想设置另一个在编译期间使用我所有内核的项目。
I found tons of references to the MSDN /MP pagebut that is for using the command line; I have yet to find any references to setting that with the IDE. How do I do that?
我发现了大量对MSDN /MP 页面的引用，但那是为了使用命令行；我还没有找到任何使用 IDE 进行设置的参考。我怎么做？
EDIT: To clarify, the two projects are completely separate and are not in the same VCPROJ file. I wanted to turn on support for multiple cores during the C++ compilation phase.
编辑：澄清一下，这两个项目是完全独立的，不在同一个 VCPROJ 文件中。我想在 C++ 编译阶段开启对多核的支持。

To enable /MP option you could add it to Project Settings->C/C++->Command Line|Additional options. This is the only way to switch it on in vcproj.
要启用 /MP 选项，您可以将其添加到Project Settings->C/C++->Command Line|Additional options. 这是在 vcproj 中打开它的唯一方法。
