各位大侠：
      我WINDOWS2000下安装了一个，然后安装一个skyeye。
在运行下面安装步骤
./configure  --target=arm-elf  --prefix=/usr/local

经过运行，最后出现的错误信息如下：
updating cache ../../config.cache
e:\cygwin\bin\sed.exe: *** thread handle not set - 0x0<0x0>, Win32 error 31
./configure: tr: permission denied
creating ./config.status
./configure: Cannot fork: Permission denied
./configure: Cannot fork: Permission denied
./config.status: Cannot fork: Permission denied
configure: error: ./configure failed for itcl
Configure in /usr/src/skyeye/itcl failed, exiting.
请求大侠给指点一下，在此，小弟不胜感激！！！
