[lfs@localhost patch-2.5.4]$ CPPFLAGS=-D_GNU_SOURCE ./configure --prefix=/tools
creating cache ./config.cache
checking host system type... configure: error: can not guess host type; you must specify one
已经做过了cc连接,config.log文件内容是:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
configure:573: checking host system type
还是这个错误啊???
