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（我想在服务器上自定义我的环境）。一个问题是全球有很多包已经过时（例如，python 2.7、gcc 4.8.5、gmake 3.82）。

在这个设置中，我从LFS的第4章开始，到处更改PATH从/tools到/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 的章节。

在这之后，一切都编译好了，我在the sanity check step 上被阻止了。我从sources/glibc/build文件夹中执行它，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，它适用于 crt1.o 和 crti.o，但不适用于其他文件。

> ln -s /path/to/my/folder/tools/lib/crti.o crti.o
> ln -s /path/to/my/folder/tools/lib/libc_nonshared.a libc_nonshared.a

collect2: error: ld returned 1 exit status

更新 1 现在我重新安装了旧版本 LFS (8.1)，因此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

受到类似问题LFS 7.2 glibc-2.16.0 make error 的启发，并尝试相应地更改LD_LIBRARY_PATH。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issue 中描述的步骤。另外，我使用了 cmets here 中描述的 -Xlinker --verbose 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。

您能否给个建议，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！

Answer 1

我正在和你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

发出警告：

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

希望这有助于发现问题。

Answer 2

此命令将为整个 shell 更新 LD_LIBRARY_PATH：

export LD_LIBRARY_PATH=/path/to/my/folder/tools/lib

您只想为一个命令更新它。试试这个：

LD_LIBRARY_PATH=/path/to/my/folder/tools/lib $LFS_TGT-gcc dummy.c

更新：那没用……试试这个怎么样？

$LFS_TGT-gcc -L/path/to/my/folder/tools/lib dummy.c

Answer 3

从 gcc 脚本中检查这一行 --with-glibc-version=2.11 \ 中的 glibc 版本以及主机系统要求的版本。
