gcc第二遍出错

bjtuwanglei

宿主系统：红旗workstation 5.0
之前安装expect按LFS6.1所说提示TCLPATH没有头文件，就重新设置了下TCLPATH为tcl的源码目录。

在这之前的所有都事严格按LFS6.1所做，没有任何差错，包括调整工具链，还手动检查了gcc的specs文件。

晨想

不知道是不是因为 红旗的gcc或者binutils没有把 regex 包括进去？

没碰到过这个问题。google也没什么很好的答案。

问题解决了，原因是这样：
1.LFS6.1上已经说在编译gcc第一遍后可以删了源码目录
2.在编译第二遍的时候，LFS6.1是按照你已经删除了gcc第一遍的目录做的
3.我呢，gcc第一遍没有删除源码目录，因为有做出来LFS的留着说还有用
4.在编译gcc第二遍的时候，LFS6.1说应该在源码目录外再弄一个目录编译，我就在第一遍的gcc源码目录下又建了个gcc-build，这样就有两个目了/mnt/lfs/gcc-build/gcc-build
5.这样编译会出错，因为有两个相同的目录，具体原因由于我是新手，也不太清楚。
6.我是这样解决的：把第一遍gcc源码目录改名为gcc-build-old，然后就按照LFS6.1说的那样做，就成功了

最后，没什么技术含量。
呵呵，希望像我这样的新手不要犯同样的错误。

很多LFS新手犯过相似的错误，其实只好怪LFS手册没有直接写出安装时的绝对路径了

我想正是这样才是魅力所在
都告诉你就没什么意思了

呵呵，所言甚是！
