问题
I'm trying to build LLVM using visual studio 2012 (version 10.0). I have CMake installed and have run the following commands:
- svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
- cd llvm\tools
- svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
- cd ....
- mkdir build
- cd build
- cmake -G "Visual Studio 10" ..\llvm
Running these commands works fine, until the last step. I receive a large number of warnings(?) which are as follows:

CMake Error at cmake/modules/HandleLLVMOptions.cmake:41 (message):
Host Visual Studio must be at least 2012 (MSVC 17.0)

These files are present on my system under C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include. The command has completed but has not produced the LLVM.sln file that the documentation tells me should be created.
Could someone advise how to correct the problems that I am encountering? I appreciate whatever guidance you can offer.
回答1:
You need to put Visual Studio on your path. There's a batch file vcvars32.bat (for 32-bit compiles) or vcvars64.bat (for 64-bit compiles) you must run from the command line before you invoke CMake. That sets up all the path and other environment variables so that the compiler is "visible."
On your system, they are in
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat
and
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64\vcvars64.bat
回答2:
The cmake visual studio 10 driver is for visual studio 2010. http://www.cmake.org/cmake/help/v3.0/generator/Visual%20Studio%2010%202010.html
LLVM and clang require a compiler that can do most c++11 things.
