当我编译LFS6.1到5.12. Binutils-2.15.94.0.2.2 - Pass 2时出错，内容如下：

谢谢各位帮忙看一下

configure: error: `CFLAGS' has changed since the previous run:

这句比较可疑, 你的CFLAGS是什么, 试试用通用的非优化的CFLAGS看看, 比如i586什么的

timwong

多谢linky_fan版主回复，我还是不太明白你的意思，我在先前按文档的步骤编译没有看到有什么的错误提示，上面的提示是否说我在运行先前的步骤后`CFLAGS'已经改变。置于你提到试试用通用的非优化的CFLAGS，我应该没有优化过CFLAGS，如果优化过CFLAGS是否运行
unset  CFLAGS 还请版主详细说下我该如果做，谢谢。

你必须先将第一次编译剩下的东西删除.
[code:1]cd ../binutils-build
rm -Rf *
[/code:1]
然后再编译
[code:1]
configure ...
make ...
[/code:1]

谢谢blackwolf回复，你有意思是把sources目录下的binutils-2.15.94.0.2.2源码目录和binutils-build目录删除吗？但我有些不明白在LFS6.1文档中提到：
After installing each package, delete its source and build directories, unless specifically instructed otherwise. Deleting the sources saves space and prevents mis-configuration when the same package is reinstalled later. Only three of the packages need to retain the source and build directories in order for their contents to be used by later commands. Pay special attention to these reminders.
之后在5.3. Binutils-2.15.94.0.2.2 - Pass 1中有个warning写到：

Warning

Do not remove the Binutils build and source directories yet. These will be needed again in their current state later in this chapter.
我该如果继续下去 thanks

blackwolf

1. Binutils Pass 1 (Do not remove the build and source)
2. Adjusting Toolchain ( the Binutils Pass 1 build directory is needed at here)
3. remove the build directory
4. Binutils Pass2 (Do not remove the build and source)
5. Re-adjusting the Toolchain (the Binutils Pass2 build directory is needed at here)
6. remove the build directory
7. install the Binutils Final Pass.

hi blackwolf
首先谢谢你的回复及支持，我再重新看了一遍5.7. Adjusting the Toolchain里面果然提到：
Now that the adjusted linker is installed, the Binutils build and source directories should be removed.
你有流程已经讲得很详细了，谢谢。

当我编译LFS6.1到5.12. Binutils-2.15.94.0.2.2 - Pass 2时出错，内容如下：
lfs://mnt/lfs/sources/binutils-2.15.94.0.2.2$ mkdir ../binutils-build

我以为前面那几句是楼主mkdir后又mkdir了一遍呢
