LFS我想在CentOS v. 7.6.1810没有权限的情况下进行交叉编译sudo（我想在服务器上自定义我的环境）。一个问题是全球有很多软件包已经过时（例如，python2.7、4.8.5、3.82 gcc）gmake。
在这个设置中，我从第 4 章开始，LFS到处都PATH从更改/tools为/path/to/my/folder/tools（我相信我做得足够准确）。直到第 5.7 章，一切都很顺利。首先，Glibc 想要更新的 python 和 gmake。因此我遵循了 5.27.1 和 5.30.1 章节。
在此之后，一切都编译得很好，我在健全性检查步骤中被阻止了。我从文件夹中执行它sources/glibc/build，并得到一个错误：
> echo 'int main(){}' > dummy.c
> $LFS_TGT-gcc dummy.c

我检查了/path/to/my/folder/tools/lib/，所有想要的文件（crt1.o, crti.o, libc.so.6, libc_nonshared.a, ld-linux-x86-64.so.2）都在那里。
我尝试提供文件的符号链接，它适用于其他文件，crt1.o但crti.o不适用于其他文件。

更新 1现在我重新安装了旧版本LFS (8.1)，这样我从一开始就满足了所有先决条件。我再次从第 4 章开始，直到臭名昭著的检查才出现错误。Tim 的建议有助于系统没有被破坏，但是分段错误不允许创建 a.out：
> echo 'int main(){}' > dummy.c
> LD_LIBRARY_PATH=/path/to/my/folder/tools/lib $LFS_TGT-gcc dummy.c
Segmentation fault (core dumped)
> readelf -l a.out | grep ': /path/to/my/folder/tools'
readelf: a.out: Error: No such file
受类似问题LFS 7.2 glibc-2.16.0 的启发并尝试进行LD_LIBRARY_PATH相应更改。它似乎不起作用。

更新 2我再次重新安装了 LFS (8.1)，但这次我遵循了本期中描述的步骤。此外，我使用此处-Xlinker --verbose评论中描述的解决方案来检查 ld 日志。现在看来，它可能无法打开提到的库。仍然无法正常工作，但日志似乎发生了一些变化。

你能不能给一个建议，如何处理这个讨厌的ld问题。我知道跳过 LFS 步骤是不好的。不幸的是，我没有办法解决这个问题，但我想尽可能升级我的本地环境。谢谢！
