llvm dev - Apr 2010 - [LLVMdev] VMKit assertion failure

Hi Nicolas,
> Yes, there has been an incompatibility change recently between LLVM and
VMKit. Please use revision 100087 of LLVM until I find a workaround.
OK, done.
> Also, running on Snow Leopard is untested (VMKit does not have support for
GC on 64bits), but should work without a GC. You can also try to compile on
32bits.
How would I run VMKit without GC?

Compiling for 32 bits is not an attractive option. The problem is the GNU
classpath library, which has some unpleasant dependencies, in particular GTK+. I
get them through MacPorts, which compiles 64-bit only on Snow Leopard. I'd
have to install all that by hand to get 32-bit versions. I guess I'd rather
work with a 32-bit Linux running under VirtualBox. Long live virtualization! 
;-)

VMKit just falls back to malloc when it detects that the machine is 64bits.

Yes, running a 32bits virtualized system should work just fine.

OK, I think I can handle that ;-)

I first tried something else: compiling on an older Mac (10.5, 32 bit  
compilers) and copy the binary over to the 64-bit Mac. Of course I ran  
a quick test on the 10.5 machine to make sure that it works - but it  
doesn't:

~/Temp> javac hello.java
~/Temp> java -cp . HelloWorld
Hello World!
~/Temp> j3 -cp . HelloWorld
terminate called without an active exception
Abort trap

Here's hello.java:

class HelloWorld
{
         public static void main(String args[])
         {
            System.out.println("Hello World!");
         }
}

Any ideas?

Konrad.
