如何修复valgrind启动时的致命错误(连接libc6-dbg和libc6-dbg:i386 )

Question

这个问题无论如何都不能解决。我试图安装libc6-dbg和libc6-dbg:i386，但是没有帮助(我有64位的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.

因此，向您展示已安装的包。正如您所看到的，一切都已正确安装，但无法正常工作。我不知道该怎么做才能让它工作。

Answer 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

您可以通过运行以下命令轻松构建valgrind

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

(如果您不确定命令的作用，请不要以sudo身份运行命令)

Answer 2

valgrind正在错误的路径中查找文件。

Ubuntu在/usr/lib/debug中有一个烂摊子。如果您将/usr/lib/debug/lib和/usr/lib/debug/usr/lib统一起来，它应该可以工作。

至少，这为我解决了这个问题。

Answer 3

apt install -y libc6-dbg

这对我很管用。(注:不使用:i386。)

可能是install valgrind, Fatal error at startup的副本。
