c - LFS 5.7.Glibc-2.29 的完整性检查失败

Question

我想在没有 sudo 权限的情况下在 CentOS v. 7.6.1810 上交叉编译 LFS(我想在服务器)。一个问题是全局范围内有很多包已过时(例如，python 2.7、gcc 4.8.5、gmake 3.82)。

在此设置中，我从 LFS 的第 4 章开始，将 PATH 从 /tools 更改为 /path/to/my/folder/tools (我相信我做得足够准确)。一切顺利，直到第 5.7 章。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，一切都编译良好，我在 the sanity check step 上停止了.我从 sources/glibc/build 文件夹中执行它，并得到一个错误:

> echo 'int main(){}' > dummy.c
> $LFS_TGT-gcc dummy.c

collect2: error: ld returned 1 exit status

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(symbolic link)，它适用于 crt1.o 和 crti.o 但不适用于其他文件。

collect2: error: ld returned 1 exit status

UPDATE 1 现在我重新安装了旧版本 LFS (8.1)，这样一开始我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 的建议对系统没有被破坏的方式很有帮助，但是段错误不允许创建 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

受到类似问题的启发LFS 7.2 glibc-2.16.0 make error并尝试相应地更改 LD_LIBRARY_PATH。它似乎不起作用。

UPDATE 2 我再次重新安装了 LFS (8.1)，但这次我遵循了本 issue 中描述的步骤。 .另外，我使用了评论中描述的 -Xlinker --verbose 解决方案 here检查 ld 日志。现在看来，也许它无法打开提到的库。仍然无法正常工作，但日志似乎发生了一些变化。

你能给个建议吗，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，但我想尽可能地升级我的本地环境。谢谢!

Answer 1

我正在和您一样在不同的目录中编译 LFS。 我遵循了与您相同的步骤。并且得到了完全相同的结果。

但我想我有一个提示，你没有提到:

/path/to/my/folder/tools/bin/x86_64-lfs-linux-gnu-ld /path/to/my/folder/tools/lib/libc.so.6

给出警告:

x86_64-lfs-linux-gnu-ld:警告:找不到入口符号 _start；没有设置起始地址

希望这可以帮助发现问题。
