使用 Visual Studio 构建 LLVM

Question

我正在尝试使用 Visual Studio 2012（版本 10.0）构建 LLVM。我已经安装了 CMake 并运行了以下命令：

1. svn cohttp://llvm.org/svn/llvm-project/llvm/trunkllvm
2. cd llvm\tools
3. svn cohttp://llvm.org/svn/llvm-project/cfe/trunkclang
4. cd ....
5. mkdir 构建
6. cd 构建
7. cmake -G "Visual Studio 10" ..\llvm

运行这些命令可以正常运行，直到最后一步。我收到大量警告（？），如下所示：

这些文件位于我的系统上的 C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include 下。该命令已完成，但尚未生成文档告诉我应该创建的 LLVM.sln 文件。

有人可以建议如何纠正我遇到的问题吗？感谢您提供的任何指导。

Answer 1

cmake Visual Studio 10 驱动程序适用于 Visual Studio 2010。http://www.cmake.org/cmake/help/v3.0/generator/Visual%20Studio%2010%202010.html

LLVM 和 clang 需要一个可以完成大多数 c++11 事情的编译器。

Answer 2

您需要将 Visual Studio 放在您的路径上。在调用 CMake 之前，必须从命令行运行批处理文件 vcvars32.bat（用于 32 位编译）或 vcvars64.bat（用于 64 位编译）。这会设置所有路径和其他环境变量，以便编译器“可见”。

在您的系统上，它们在

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat

和

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64\vcvars64.bat
