No compiler1 product1 for ARCH_DATA_MODEL=64?

[Isml]

Hi everyone,    I am trying to compile a x64 version openjdk on Ubuntu 12.10 x64. I use the following commands:


    export LP64=1
    make product1(I want to compile the client jvm)


    but receive the following errors:
   
    No compiler1 product1 for ARCH_DATA_MODEL=64


    But I can successfully compile the server jvm(using make product), I check the Makefile, and find the following code:


    ifeq ($(OSNAME),windows)
  ifeq ($(ARCH_DATA_MODEL), 32)
	$(CD) $(OUTPUTDIR); \
	    $(NMAKE) -f $(ABS_OS_MAKEFILE) \
		      Variant=compiler1 \
                      WorkSpace=$(ABS_GAMMADIR) \
		      BootStrapDir=$(ABS_BOOTDIR) \
                      BuildUser=$(USERNAME) \
		      $(MAKE_ARGS) $(VM_TARGET:%1=%)
  else
	@$(ECHO) "No compiler1 ($(VM_TARGET)) for ARCH_DATA_MODEL=$(ARCH_DATA_MODEL)"
  endif
else
  ifeq ($(ARCH_DATA_MODEL), 32)
	$(CD) $(OUTPUTDIR); \
	    $(MAKE) -f $(ABS_OS_MAKEFILE) \
		      $(MAKE_ARGS) $(VM_TARGET)
  else
	@$(ECHO) "No compiler1 ($(VM_TARGET)) for ARCH_DATA_MODEL=$(ARCH_DATA_MODEL)"
  endif
endif




    It seems that x64 version client jvm is not supported, is it true?
    Thanks for any help.
