[LLVMdev] Running VMKit's AOT Java Compiler

[David Brazdil]

Hi,
I'm new to VMKit and I'm trying to use its AOT Java compiler but I'm
immediately getting an error message which I don't understand.

Everything was compiler as suggested in the Getting Started tutorial, using
GNU Classpath. I try to run:

    llcj ../../tools/trainer/Release+Asserts/HelloWorld.class

and get the following output:

    Can not materiale a function in AOT mode.0  vmjc

This is produced inside the JavaAOTCompiler.h, in
method materializeFunction which is called from JavaMethod::compiledPtr.
What am I doing wrong?

Cheers,
David
