【问题标题】：How to fix the fatal error at startup in valgrind (connected with libc6-dbg and libc6-dbg:i386 )如何修复 valgrind 启动时的致命错误（与 libc6-dbg 和 libc6-dbg:i386 连接）

【问题描述】：

有这个无法解决的问题。我尝试安装 libc6-dbg 和 libc6-dbg:i386 并没有帮助。（我有 64 位 Ubuntu 19.10）。

valgrind:  Fatal error at startup: a function redirection
    valgrind:  which is mandatory for this platform-tool combination
    valgrind:  cannot be set up.  Details of the redirection are:
    valgrind:  
    valgrind:  A must-be-redirected function
    valgrind:  whose name matches the pattern:      strlen
    valgrind:  in an object with soname matching:   ld-linux-x86-64.so.2
    valgrind:  was not found whilst processing
    valgrind:  symbols from the object with soname: ld-linux-x86-64.so.2
    valgrind:  
    valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
    valgrind:  package on this machine.  (2, longer term): ask the packagers
    valgrind:  for your Linux distribution to please in future ship a non-
    valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
    valgrind:  that exports the above-named function using the standard
    valgrind:  calling conventions for this platform.  The package you need
    valgrind:  to install for fix (1) is called
    valgrind:  
    valgrind:    On Debian, Ubuntu:                 libc6-dbg
    valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
    valgrind:  
    valgrind:  Note that if you are debugging a 32 bit process on a
    valgrind:  64 bit system, you will need a corresponding 32 bit debuginfo
    valgrind:  package (e.g. libc6-dbg:i386).
    valgrind:  
    valgrind:  Cannot continue -- exiting now.  Sorry.

所以，向您展示已安装的软件包。如您所见，一切都已正确安装，但不起作用。我不知道该怎么做才能让它发挥作用。

【问题讨论】：

连同@sam 的评论，请告诉我们您是否成功安装libc6-dbg，以及安装此软件包可能产生的任何输出。
这些包被称为libc6-dbg和libc6-dbg:i386。我想你用p而不是b拼写它们。
您应该通过包管理器安装 Valgrind：sudo apt-get install valgrind。
您从构建 Valgrind 的目录中运行 sudo make uninstall，然后运行 sudo apt-get install valgrind。
发行版向 Valgrinds 调试搜索路径添加了特殊路径。

【解决方案1】：

我在 Ubuntu 20.04 上遇到了同样的问题。正如用户 phd 在他们的评论中指出的那样，这是一个 Valgrind 错误，已在提交 db07db4c8706d17124a621a254bee1b6f08d2e1d 中修复

你可以通过运行类似的东西轻松构建 valgrind

git clone git://sourceware.org/git/valgrind.git
cd valgrind
./autogen.sh
./configure
make -j
sudo make install

（如果您不确定它们的作用，请不要以 sudo 运行命令）

【解决方案2】：

valgrind 正在寻找错误路径中的文件。

Ubuntu 在/usr/lib/debug 中一团糟。如果你统一 /usr/lib/debug/lib 和 /usr/lib/debug/usr/lib 应该可以工作。

至少，这为我解决了问题。

【解决方案3】：

apt install -y libc6-dbg

它对我有用。（注意：没有:i386。）
install valgrind, Fatal error at startup 的可能重复项。
