如何使Visual Studio中使用本地AMD64工具链 [英] How to make Visual Studio use the native amd64 toolchain

问题描述

我怎样才能获得的Visual Studio 2012使用本地AMD64工具链，而不是默认的x86_amd64交叉编译器？

How can I get Visual Studio 2012 to use the native amd64 toolchain, rather than the default x86_amd64 cross-compiler?

我建立一个大型图书馆，导致链接器做的整个程序优化和链接时code代时耗尽内存。

I am building a large library that causes the linker to run out of memory when doing whole program optimization and link-time code generation.

我找到了两个旧帖子（<一href="http://stackoverflow.com/questions/10731090/how-to-enable-native-64-bit-compiler-in-visual-studio">here和<一href="http://stackoverflow.com/questions/14188380/how-to-make-visual-studio-2012-call-the-the-native-64-bit-visual-c-compiler-in">here)问同样的问题，但没有解答。微软提供了有关如何指定工具链的上的命令行的，但不是在IDE

I found two older posts (here and here) asking this same question, but no answers yet. Microsoft provides documentation on how to specify the toolchain on the command line, but not in the IDE.

推荐答案

您需要设置环境变量_IsNativeEnvironment为真之前，要启动的Visual Studio 2012 IDE：

You need to set the environment variable "_IsNativeEnvironment" to "true" prior to starting Visual Studio 2012 IDE:

set _IsNativeEnvironment=true
start "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" your_solution.sln

对于Visual Studio 2013，环境变量的名称是不同的：

For Visual Studio 2013, the name of the environment variable is different:

set PreferredToolArchitecture=x64
sbm start "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe" your_solution.sln

要注意的是这种技术不工作，如果在IDE的版本不匹配的工具链的版本。也就是说，如果你使用VS2013 IDE配置为运行VS2012的编译器，你的运气了。但是，这样的组合是罕见的。

Beware that this technique does not work if the version of the IDE does not match the version of the toolchain. That is, if you use VS2013 IDE configured to run VS2012 compiler, you are out of luck. But such combination is uncommon.
