GCC4.03第一遍configure出错

用LiveCD（LFS6.2）做宿主系统，用CD上的源码。可是在5.4节第一遍编译GCC4.03的时候出错。下面是configure的输出信息：
lfs:/mnt/lfs/sources/gcc-build/gcc-4.0.3$ ./configure --prefix=/tools --with-local-prefix=/tools --enable-share --disable-nls > --enable-languages=c
loading cache ./config.cache
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking build system type... i686-pc-linux-gnu
checking for a BSD compatible install... /usr/bin/install -c
checking whether ln works... yes
checking whether ln -s works... yes
configure: error: Building in the source directory is not supported in this release. See http://gcc.gnu.org/install/configure.html for more details.

下面是config.log文件内容：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

configure:595: checking host system type
configure:616: checking target system type
configure:634: checking build system type
configure:689: checking for a BSD compatible install
configure:742: checking whether ln works
configure:766: checking whether ln -s works

请教各位是什么错误。谢谢~

configure: error: Building in the source directory is not supported in this release. See http://gcc.gnu.org/install/configure.html for more details.

我也这样问题
谁能给说下什么回事

汗，上面不是说得很明白吗

configure: error: Building in the source directory is not supported in this
配置错误 : 在源代码所在的文件夹进行建立(其实就是编译)在本版中不支持
release. See http://gcc.gnu.org/install/configure.html for more details.
看 http://gcc.gnu.org/install/configure.html 得到更多的细节

你应该另建一个 gcc-build与gcc-4.03平级，然后到 gcc-build中进行编译。

手册上说得很清楚了吧。

这个意思阿 ..
手册上说推荐在新目录下编译,我看他说推荐就没管它...
