Visual Studio:如何使用平台工具集作为预处理指令? [英] Visual Studio: How to use platform toolset as preprocessor directive?
问题描述
我有两个平台工具集:v110和v110_xp为我的项目,并根据所选择的平台,我想包括/排除部分代码编译。
I have two platform toolsets: v110 and v110_xp for my project, and depending on the chosen platform I want to include/exclude part of the code to be compiled.
_MSC_FULL_VER
和 $(PlatformToolsetVersion)
这两个平台工具集的值相同。或者,我尝试使用 $(PlatformToolset)
如下:
_MSC_FULL_VER
and $(PlatformToolsetVersion)
have exactly the same value for both of these platform toolsets. Alternatively, I tried to use $(PlatformToolset)
as follows:
_MSC_PLATFORM_TOOLSET=$(PlatformToolset)
但问题是 $(PlatformToolset)
是非数字。我想知道如何使用这个非数字值作为预处理器指令?
but the problem is that $(PlatformToolset)
is non-numeric. Was wondering how can I use this non-numeric value as a preprocessor directive?
尝试几个解决方案我想出了
Trying several solutions I figured out that
_MSC_PLATFORM_TOOLSET='$(PlatformToolset)'
#if (_MSC_PLATFORM_TOOLSET=='v110')
[Something]
#endif
工作正常,但
#if(_MSC_PLATFORM_TOOLSET == 'v110_xp')
[SomethingElse]
#endif
b $ b
会导致字符常数字符过多错误。
对于上下文,请参见类似问题:

推荐答案
转到项目属性 - C / C ++ - >预处理程序
并将以下内容添加到预处理程序定义
:
Go to project properties -> C/C++ -> Preprocessor
and add the following to Preprocessor Definitions
:
_MSC_PLATFORM_TOOLSET _ $(PlatformToolset)
然后你可以这样写:
#ifdef _MSC_PLATFORM_TOOLSET_v110
[Something]
#endif
#ifdef _MSC_PLATFORM_TOOLSET_v110_xp
[SomethingElse]
#endif
这适用于VS2010。
This works for me in VS2010.
