llvm dev - Nov 2008 - [LLVMdev] compiling the tutorial

Hi,
I'm investigating adding LLVM JIT support to a project of mine, but I'm 
having issues when trying to compile the Kaleidoscope tutorial* under 
MSVC 2008.
In particular, the problem is that in main() when this line is
executed
>   // Create the JIT.
>   TheExecutionEngine = ExecutionEngine::create(TheModule);
create returns null, because both JITCtor and InterpCtor are null.
I found this comment in ExecutionEngine.h
>   // To avoid having libexecutionengine depend on the JIT and interpreter
>   // libraries, the JIT and Interpreter set these functions to ctor 
> pointers
>   // at startup time if they are linked in.
>   typedef ExecutionEngine *(*EECtorFn)(ModuleProvider*, std::string*,

>   static EECtorFn JITCtor, InterpCtor;
so I suppose that somehow I'm missing a library, but in my project 
settings I added "<path_to_project>\llvm\*.lib" in the 
linker>input>additional dependencies (proof it works is that the 
tutorial compiles and links just fine), and the contents of that 
directory are
> Analysis.lib
> analysis.pdb
> Archive.lib
> archive.pdb
> AsmParser.lib
> asmparser.pdb
> Bitcode.lib
> bitcode.pdb
> CBackend.lib
> cbackend.pdb
> CodeGen.lib
> codegen.pdb
> ExecutionEngine.lib
> executionengine.pdb
> Linker.lib
> linker.pdb
> support.lib
> support.pdb
> System.lib
> system.pdb
> Target.lib
> target.pdb
> Transforms.lib
> transforms.pdb
> VMCore.lib
> vmcore.pdb
> x86.lib
> x86.pdb
i.e. all the libraries created by the bundled llvm msvs solution, except 
for the CLI programs.
so I'm stuck, because it looks like the libraries are being linked 
(otherwise the tutorial wouldn't even link) but somehow something goes 
wrong and those static variables are not set. I also tried to place a 
breakpoint on JIT::Register() but it is never reached. any clue why?
my environment is Vista x86 SP1, MSVS 2008.
thank you very much for your attention,
Carlo Alberto Ferraris

* great tutorial, btw!

Does it work if you add to the link command
/INCLUDE:_X86TargetMachineModule

?

I tried linking the tutorial adding that command but JITCtor and 
InterpCtor are still null, both in debug and release builds.
Was by any chance that command meant to be used when building the llvm 
solution?
