[LLVMdev] [VMKit-2.7] libvmjc.so building problem

[Linghua Tseng]

I followed instructions in this page to setup my environment:
  http://vmkit.llvm.org/get_started.html

My llvm, llvm-gcc, and vmkit are not SVN version.
All of them are downloaded from this page:
  http://llvm.org/releases/download.html#2.7
GNU classpath is downloaded from:
  ftp://ftp.gnu.org/gnu/classpath/classpath-0.97.2.tar.gz
PNet & PNetlib are not used because I just want the JVM.

I use these arguments to configure my VMKit:
./configure --prefix=/home/lhtseng/llvm
                  --with-llvmsrc=/home/lhtseng/llvm/src/llvm
                  --with-llvmobj=/home/lhtseng/llvm/obj/llvm
                  --with-gnu-classpath-libs=/home/lhtseng/llvm/lib/classpath
                  --with-gnu-classpath-glibj=/home/lhtseng/llvm/share/classpath/glibj.zip
                  --with-llvmgcc
                  --with-gc=mmtk
and then use `make ENABLE_OPTIMIZED=1' to build it
(I follow the instructions in this page: http://vmkit.llvm.org/use_mmtk.html)
After it's done, `j3' works properly.

Then I follow these instructions to enable AOT compilation:
  http://vmkit.llvm.org/use_aot.html
  * cd tools/vmjc/libvmjc
  * make ENABLE_OPTIMIZED=1 REQUIRES_FRAME_POINTER=1
And an error is occurred:

Someone suggested me to use GCMmap2 without llvm-gcc instead of MMTk.
So I use the following arguments to reconfigure my VMKit:
./configure --prefix=/home/lhtseng/llvm
                  --with-llvmsrc=/home/lhtseng/llvm/src/llvm
                  --with-llvmobj=/home/lhtseng/llvm/obj/llvm
                  --with-gnu-classpath-libs=/home/lhtseng/llvm/lib/classpath
                  --with-gnu-classpath-glibj=/home/lhtseng/llvm/share/classpath/glibj.zip
                  --with-gc=multi-mmap
Now libvmjc.so can be generated (It takes 80+ minutes on Intel i7 920).

I use this command for testing the AOT compilation:
  llcj --main=HelloWorld HelloWorld.class -o test
A lot of undefined reference errors occurred:

All of them have the suffix `_VirtualMethods'.

Do I miss some important steps?

To checkout llvm, llvm-gcc, and vmkit from SVN's release_27 doesn't help me.
release_28 & trunk version of llvm cannot build the trunk version of vmkit (llc complains it doesn't support '-f' option).
