[LLVMdev] Build errors for vmkit

[Nicolas Geoffray]

Dear Michael,

The symbols that are said undefined by the compiler live in  
libAllocator.a. That file should be in Release/lib/, do you have it?  
It is possible that the compiler has linking order problems. What is  
the version of your gcc?

You can try changing the link order of the make command by editing  
tools/vmkit/Makefile.

Also, you should know that the GC of vmkit does not work on a 64bit  
system, so if you need the GC, you should try to emulate a 32bit system.

Let me know how that worked for you.

Nicolas
