llvm dev - Jul 2013 - [LLVMdev] Build Clang and LLVM on Win 8

Hi all,
   I'm new to Clang and LLVM and I'd like to use them on Win 8 with 
Code::Blocks.

I'm having problems in running cmake.

I did the following:

  * Installed cmake
  * installed Code::Blocks
  * Installed python (cmake was complaining if it was not installed)
  * Dowloaded sources fron svn (LLVM, clang, compilre-rt and test-suite.


When I run cmake I got The following error:
*<project folder>\build>CMake -G "CodeBlocks - MinGW
Makefiles" ..\llvm*
/-- Could NOT find LibXml2 (missing:  LIBXML2_LIBRARIES 
LIBXML2_INCLUDE_DIR)//
//-- Target triple: x86_64-w64-mingw32//
//-- Native target architecture is X86//
//-- Threads enabled.//
//-- Found PythonInterp: C:/Python33/python.exe (found version
"3.3.2")//
//-- Constructing LLVMBuild project information//
//CMake Error at CMakeLists.txt:299 (message)://
//  Unexpected failure executing llvm-build: Traceback (most recent call 
last)://
//
//    File "<project folder>/llvm/utils/llvm-b//
//uild/llvm-build", line 3, in <module>//
//      import llvmbuild//
//    File "<project folder>\llvm\utils\llvm-b//
//uild\llvmbuild\__init__.py", line 1, in <module>//
//      from main import main//
//
//  ImportError: No module named 'main'//
//
//
//-- Configuring incomplete, errors occurred!/

So I thought that I missed to configure something.
I tried to run the configure script as per the web instructions, but I 
got an error because the configure script is only for linux


*<project folder>\build>..\llvm\configure
--p**refix="c:\llvm\tools"*/
//"..\llvm\configure" is not an internal/external command, an
executable
or batch file.///

May anyone please help me?
I downloaded the last version of LLVM (3.4).

Thanks in advance,
   Giorgio Franceschetti

I think that you installed the wrong version of Python. IIRC llvm-build
requires Python 2.X

There was a patch on the commit list to try to make some of our scripts
work for both 2 and 3.  I should dig it up and review it.

My initial impression was that still probably nobody uses python 3, so it's
not worth adding support that will break.  But if users actually have
python 3, maybe it's worth it.
