而网上所给结果应当是全部通过。查询LFS BOOK，发现这个库是gcc支持范围检查的库，不知道会有什么后果，是怎么出的问题？

不知道怎么系统响应有问题，居然一下子发出了三个贴，请版主帮忙删一下吧。

通过与否都有特定条件的，无需担心，反正俺是从来不 check 的。。。

gcc 4.2.2 好象和很多软件都不兼容，我用回4.1.2就好了，所以建议楼主还是用4.1.2吧。

d00m3d

俺一直用 gcc-4.2.2 不亦樂乎，樓上有哪些軟件有問題了？

再者 gcc 可以多版同存，真的不兼容的時候才用舊版也行

　　我觉得挺多的，vim 71不能编译通过，XFree86 不能编译通过，openSSH编译能通过但是安装后ssh 2功能打不开，只能以ssh 1方式运行，呵呵。
　　换回gcc 4.1.2 就一点问题都没有了。

1. SVN 裡的 gcc 是 4.2.2，vim 是 7.1，沒問題，也許是有補丁未打吧

http://www.linuxfromscratch.org/ ... /chapter06/vim.html

2. XF86 早已過時，還不轉用 Xorg？

3. OpenSSH 也無此問題，編譯及使用都順利

怎么gcc-4.2.2有那么多问题吗？我现在系统已经基本上编译完成了，所以我看两个版本的测试结果相似，只是 libmodflap 有同样的测试问题，就冒然用 gcc-4.2.2 替换了 gcc-4.1.2 版本。希望以后的再生不会有问题吧，要不然还真是麻烦了。

   实际上我是在LFS6.3的系统上同时编译了两个版本(打开了所有的编译器，主要是想用 ada 和 fortran)，只不过最后安装了 gcc-4.2.2版本！如果最后发现这个版本不能再生，是否可以通过解开保存的 gcc-4.1.2 编译结果目录，直接用 make install 来换回 gcc-4.1.2 版本？真是有趣的问题。

想到了一个很重要的问题，发到新帖上了。

　　我是用ALFS直接编译的SVN版LFS，e2fsprogs-1.40也是编译通不过的，每次用ALFS都要手工修改一下e2fsprogs和vim的脚本，才能直接编译成功。
　　之所以用XFree86是因为他好编译，一个包就可以了，不象xorg要编译好多东西。
