llvm dev - Feb 2009 - [LLVMdev] problem with execution engine on windows

Dear llvm-dev,

First of all I'd like to thank LLVM developers for doing a great job!

I am trying to use LLVM libraries on Windows using Visual Studio environment and
everything works very smoothly until it comes to the execution engine. I
construct a module and obtain a pointer to the function in it using
ExecutionEngine::getPointerToFunction but calling this function (after
appropriate cast) causes the following error:

Unhandled exception at 0x0122a5bc in sampl.exe: 0xC000001E:  An attempt was made
to execute an invalid lock sequence.

The function I am trying to call is trivial (took it from the tutorial just for
testing purposes) and has C calling conventions. The execution engine returned
by ExecutionEngine::create is Interpreter.

Am I doing something wrong or is it a bug?

And another question: is JIT supported on Windows?

Thank you in advance,
Viktar

Are you using CMake for generating the Visual Studio project files? If
the answer is yes, please check

http://www.llvm.org/docs/CMake.html

specially the last section of the page.

Yes.

Yes, I am using CMake and the addition
"/INCLUDE:_X86TargetMachineModule" compiler option as described in
that document partially solved the problem, thank you. After some debugging and
browsing the LLVM headers I finally solved it by including
"llvm/ExecutionEngine/JIT.h". I would be helpful to document this as
well.

Viktar
