kaffe是一个java虚拟机的源代码。里面包含了一些java例程和标准的java包。

# This is a magic wrapper for the link step in Kaffe.  It 
# supplies all of the necessary OSKit libraries (of which
# there are many all of which have odd ordering dependencies).
#
# The --oskit=* option is set by the oskit-configure shell script.
#
# XXX could use a --bootloader=foo option
#

# the OSKit install directory
oskit=/z/oskit

# The gcc version to use.

# The bootloader-specific .o to link in
bootloaderObject=multiboot.o
#bootloaderObject=dos.o

# Uncomment/Comment this line to include/remove memdebug support

# the proper  oskit_<OS>_m library
