Please modify the address layout parameters BOOTIMAGE_DATA_ADDRESS and/or
MAXIMUM_MAPPABLE_ADDRESS in the RVM_{HOST,TARGET}_CONFIG files.
Either BOOTIMAGE_DATA_ADDRESS must be greater than 0xA7F02000 or
MAXIMUM_MAPPABLE_ADDRESS must be less than A7F02000.
Having modified the value re-run jconfigure and then re-run jbuild.
jbuild.linkBooter: Exiting unexpectedly with status 1.
jbuild.linkBooter:1: some command we just ran (probably with a
final argument of "unexpected_exit") exited with status 1,
jbuild.linkBooter: Aborting execution.

jbuild: Trouble while running "./jbuild.linkBooter " (exit
status 1); aborting execution
Successful Build:
If I try to build with smaller value of MAXIMUM_MAPPABLE_ADDRESS
like
export MAXIMUM_MAPPABLE_ADDRESS=0x999999999
It build properly. But its behaviour is unknown. I am able to run few programs with it. But I was not able to get eclipse running with this configuration.

This isn't an error so I'm closing the bug. The build system has alerted you to a potential problem with the address layout in the configuration file - MMTk would overlap with libraries linked against the boot image runner (JikesRVM) on your OS. You've fixed the problem but I would suggest an aligned value of 0xA0000000 is better than 0x99999999 (this is > 32bits ?!?). Given your build works the eclipse error should be reported as a new bug if it persists.
