“ Permission denied”是什么问题？？？

偶把cygwin安装好之后，编译skyeye的时候，出现了下面的提示：
./configure: fork: Permission denied
checking for sys/pte.h... ./configure: fork: Permission denied
./configure: line 1604: /usr/bin/rm: Permission denied
./configure: line 1613: /usr/bin/rm: Permission denied
yes
./configure: fork: Permission denied
./configure: line 1618: /usr/bin/cat: Permission denied
