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 0x0000000000f2cea5 llvm::sys::PrintStackTrace(_IO_FILE*) + 37

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