Hi Gabe,

Thank you for your reply. I found the similar problem in the mailing list
with your answers (
http://comments.gmane.org/gmane.comp.emulators.m5.users/6604). And I did
install build-essential as well as g++. But there still came the error. Is
there any other possible solutions?


Thanks,
Yingying Tian
