c++ - 如何在valgrind中启动时修复 fatal error (与libc6-dbg和libc6-dbg:i386连接)

Question

遇到无法解决的问题。我尝试安装libc6-dbg和libc6-dbg:i386，但没有帮助。(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.

因此，请向您显示已安装的软件包。如您所见，所有内容均已正确安装，但无法正常工作。我不知道该怎么做才能使其正常工作。

我在Ubuntu 20.04中遇到了同样的问题。正如phd用户在其评论中指出的那样，这是Valgrind错误，已在commit db07db4c8706d17124a621a254bee1b6f08d2e1d中修复

您可以通过运行类似的内容轻松构建valgrind

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

(如果不确定命令的用途，请不要以sudo的身份运行命令)
