lfs自己做过一次。
虽然也不是特别懂。
不过最后安然无恙的在虚拟机上跑起来了

求助 ： 我的情况是这样的     mac os  10.10  
安装 binutils-2.25   
第一次编译的时候没有任何问题，./configure  ,make  ,make install
装好之后 原文件删掉了，可是问题就出来了 ，第二次编译的  binutils-2.25 时候就开始报ld 错了   包括编译 gcc 源码 也报ld 错
Ξ nasm/build → clang -v
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)

$gdb
this GDB was configured as follows:

             --with-separate-debug-dir=/usr/local/lib/debug (relocatable)
             --with-zlib
             --without-babeltrace
我想问问这个target 是怎么回事 还有 --host

第二次编译 binutils-2.25 如下错误 麻烦楼主帮忙分析下， 不甚感激。应该是编译ld 的时候出错，然后是 size 命令。但是 第一次没错，第二次却有错了，不知道原因所在。

我好像第二次编译的时候，是用第一次编译的 gcc 做的。

年代久远，记得不是很清楚了。
