编译器无法在使用cmake配置的Visual Studio项目中执行C ++ 11指令 [英] Compiler failing on C++11 instructions in a Visual Studio project configured with cmake

问题描述

我正在尝试在带有Visual Studio 2012的64位Windows计算机上构建voxelterrain库（C ++，Ogre）。CMake似乎可以正常运行（请参见下面的输出）。当我尝试编译库时，收到几个错误。我不了解CMAKE，但我认为编译器无法正确解释C ++ 11。

I am trying to build the voxelterrain library (C++, Ogre) on a 64 bit Windows Machine with Visual Studio 2012. CMake seems to run without an error (see output below). When I try to compile the library I receive several errors. I have no idea about CMAKE but I assume that the compiler is not interpreting C++11 correctly.

例如：
此代码...

For example: this code ...

 template <class T>
    using weakPointer = std::weak_ptr<T>;

出现此错误：

error C2988: Unerkannte Vorlagendeklaration/-definition
error C2059: syntax error : 'using'
error C2143: syntax error : missing ';' before '{'
error C2447: '{': missing function header (old-style formal list?

此处为源和CMAKE文件：

here the source and CMAKE file:

VoxelTerrain库： http：// voxelterrain。 com / index.html

VoxelTerrain Library: http://voxelterrain.com/index.html

CMake文件： https://github.com/qwertzui11/voxelTerrain/blob/master/CMakeLists.txt

CMake输出：

 CMake Warning (dev) at CMakeLists.txt:20 (if):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted variables like "MSVC" will no longer be dereferenced when the policy
  is set to NEW.  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

推荐答案

本文说，Visual Studio 2012不支持别名模板。

This article says that Visual Studio 2012 does not support alias templates.

尽管它们在Visual Studio 2013中受支持。

They are supported in Visual Studio 2013 though.
