llvm dev - Oct 2011 - [LLVMdev] Issues with running the LLVMHello Pass on Windows

Hi,
I was trying to write a LLVM Pass, so I first read
http://llvm.org/docs/WritingAnLLVMPass.html#quickstart about how to write a
llvm pass. Here, under setting up the build environment settings, it was
instructed to configure and build LLVM directly inside the LLVM source tree
rather than in a separate objects directory.
Now, my LLVM source tree is C:\LLVM\llvm-2.9 while my build is in
C:\LLVM\llvm-2.9\BUILD ( as per the instructions given here
http://lyuts.net/blog/2010/06/llvm-clang-mingw ).
So, I decided to delete my build and rebuild it directly inside the LLVM
source directory ( C:\LLVM\llvm-2.9 ) and I read this page on how to build
LLVM using CMake http://llvm.org/docs/CMake.html. But, this page says that
"CMake is not supported to build LLVM on the source directory". Do
they not
contradict each other?
I have been trying to build LLVM and run this Hello pass (
C:\LLVM\llvm-2.9\lib\Transforms\Hello\) for quite some time and tried many
methods, but sadly without successful results. Can someone please give me *the
correct and tested steps* about 1. how to configure and build LLVM in
windows 2. how to run an LLVM pass in Windows.

There is no *correct and tested* step.
For now;

1) CMake build does not handle plugins.
2) configure --enable-shared would be needed. (--enable-optimized
would be needed too)
3) You might need --enable-embed-stdcxx
4) You should build Hello manually after building llvm-shlib.
  $ make -C lib/Transforms/Hello

I have not checked recently if they could work.
Lemme know if you met any faults.
