xerces-c 2.8.0 在cygwin下编译不过!

[blackheart99]

你们好, 我下载了xerces-c-2.8.0, 有一篇文档 http://xerces.apache.org/xerces-c/build-winunix-2.html#CygWin,

我就是安照它的方法,在cygwin下,设置XERCESCROOT = /home/mytest/xerces-c-src_2_8_0
运行 ./runConfigure "-p cygwin -c gcc -x g++
等一会,有一个保错:
$ ./runConfigure -p cygwin -c gcc -x g++

我怎么解决?
