[LLVMdev] problems building vmkit

[Zoe Wolk]

Hi All,

Thanks Nicolas for pointing out that I needed --enable-targets=x86,cpp for
my
llvm config to get vmkit to build.  The process gets a lot farther but fails
in
different places depending upon the vmkit config (Can you please see the
three
case below?).

My machine is a intel core i7 running ubuntu karmic and gcc 4.4.1.
What arch/OS/distro/gcc do you all have VMKit working on?

thanks for your help.

1) For any configuration with (pnet and pnetlib build successfully):
--with-pnet-local-prefix=/home/zoewolk/RESEARCH/pnet-0.8.0
--with-pnetlib=/home/zoewolk/RESEARCH/pnetlib-0.8.0
I get that TRACER is undefined.  I messed with this some but there are two
tracer functions depending on the gc
(tracer() and tracer(...)).  I'm not sure about the authors intent.
I tried with llvm-gcc/mmtk and without it, any config with pnet-based N3
fails
in this way.  I didn't try via mono.

It makes it much farther but stops here:

4) This is the only build that I can get to finish without error (just fyi):
./configure --with-llvmsrc=/home/zoewolk/RESEARCH/LLVMSystem/llvm
--with-llvmobj=/home/zoewolk/RESEARCH/LLVMSystem/llvm
--with-gnu-classpath-glibj=/home/zoewolk/RESEARCH/classpath-0.97.2/lib
--with-gnu-classpath-libs=/home/zoewolk/RESEARCH/classpath-0.97.2/lib
--with-llvmgcc=/home/zoewolk/RESEARCH/LLVMSystem

However j3 segfaults immediately for j3 --help.
vmjc, vmkit, llcj with the -version flag, give the version.  I've not tested
beyond this.
