How to build VirtualBox OSE 64bit version on windows?

[QiaoJie]

Hello everyone,

I followed this guide to build VirtualBox OSE(the code is the lastest version on svn) 32bit version success.
http://forums.virtualbox.org/viewtopic.php?f=10&t=27888

Now I want to build 64bit version. But I didn't find any useful guidance. I tried to do:
env
kBuild\envwin.cmd --win64
kmk


then I get the error message:

I checked the makefile

RuntimeR3NoCRTGCC_TEMPLATE = VBOXNOCRTGCC

ifeq ($(KBUILD_TARGET).$(KBUILD_TARGET_ARCH),win.amd64)
# cross compile to 64-bit ELF (linux).
TEMPLATE_VBOXNOCRTGCC_TOOL = XGCCAMD64LINUX
TEMPLATE_VBOXNOCRTGCC_ASTOOL = YASM
TEMPLATE_VBOXNOCRTGCC_ASFLAGS = -f elf64 -DASM_FORMAT_ELF -D__YASM__ -w+orphan-labels -g dwarf2
TEMPLATE_VBOXNOCRTGCC_LIBS = $(PATH_DEVTOOLS)/win.x86/x86_64-unknown-linux-gnu/20060701-r2/lib/gcc/x86_64-unknown-linux-gnu/3.4.6/libgcc.a
TEMPLATE_VBOXNOCRTGCC_LDFLAGS = -nostdlib

It seems there is no 64bit GNU compiling tool on windows.

How can I do?

This was VBox 3.x though.
