出错了，这是为什么呢？

第二次编译GCC时，如下：

前面是重复的一大段的“

刚刚十秒钟就停在这里了。

我用的是lfs-4.0rc1

tram

有没有解压gcc和g++两个包？
4.0rc1好像没分吧？我记不太清了。

ainxtein

4.0只有一个包。解压以后，有libstdc++-v3的目录。

我下了另外的一个包，分gcc-core-3.2和gcc-g++-3.2，解了，仍然有错误。

我的LFS的第五章都没有出错。

编glibc的时候也没有错。

gcc的时候就不行了。

ainxtein

我下了另外的一个包，分gcc-core-3.2和gcc-g++-3.2，解了，仍然有错误。
错误与一个包的相同。
我的系统使MDK-9.1
