I suspect that when you built LLVM, you built with the Debug build type
instead of Release. That's why you need LLVM_USE_CRT_DEBUG= instead of
LLVM_USE_CRT_RELEASE=. But I don't recommend you use a Debug LLVM
build, it can be much slower.
To be safe, I could update the instructions to mention both
LLVM_USE_CRT_DEBUG/RELEASE=
But you're right about a typo there: the 2nd -DLLVM_USE_CRT_RELEASE=
should have "MT", not "MTd".

Thanks everyone.
I was able to compile it using the instructions Jose sent from this

However, I believe there's a typo in that page. In the text I've pasted
below, the highlighted RELEASE should be DEBUG.
Thanks again,

For Windows you will need to build LLVM from source with MSVC or MINGW
(either natively or through cross compilers) and CMake, and set the LLVM
environment variable to the directory you installed it to. LLVM will be
statically linked, so when building on MSVC it needs to be built with a
matching CRT as Mesa, and you'll need to pass -DLLVM_USE_CRT_RELEASE=MTd
for debug and checked builds, -DLLVM_USE_CRT_RELEASE=MTd for profile and
release builds. You can build only the x86 target by passing
-DLLVM_TARGETS_TO_BUILD=X86 to cmake.

Thank you. ____
I have compiled llvm with /MDd options, but Mesa doesn't accept that

So I compiled llvm with /MTd and it worked.____
However, I prefer to change Mesa to dynamic option, but I don't know
how to do that. I tried the following, but got another error:____

P.S. You're right Marius. It was a typo. I missed the i at the end

Hi,____
____
I'm trying to build mesa on windows (MSVC) with gles support and
with llvm.____
Here are the keys I'm using:____
scons.py gles=yes llvm=yes platform=windows libgl-gd____
____
I'm getting a bunch of errors like this:____
____
LLVMCore.lib(ValueSymbolTable.obj) : error LNK2038: mismatch
detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't
match value 'MTd_StaticDebug' in mesa.lib(uniform_query.obj)____
____
I understand that this is due to mismatch between the runtime
libraries, but I don't know how to fix it.____
Should I change the CRT in llvm or in mesa? How should I do that? ____
