Ian, Thanks for your information. Currently, gcc was built completely. And I type ./i686-pc-linux-gnu-gcc -print-search-dirs, the libraries haven't include the system path. That is what I need. But it seems there are lots of other issues. such as can't found ld and stdlib. I'm going to investigate these issues. Thank you again. --- 09年3月25日，周三, Ian Lance Taylor <iant@xxxxxxxxxx> 写道： > 发件人: Ian Lance Taylor <iant@xxxxxxxxxx> > 主题: Re: I would like to build a gcc that don's search /lib and /usr/lib when compiling others. > 收件人: duanxun@xxxxxxxxxxxx > 抄送: gcc-help@xxxxxxxxxxx > 日期: 2009年3月25日,周三,下午2:34 > duanxun <duanxun@xxxxxxxxxxxx> > writes: > > > I tried to using --target=i686-pc-linux-gnu > --host=i586-pc-linux-gnu > > Don't use --host without also using --build.
