Question

我正在安装Valgrind但遇到一些问题。我平台的信息：

Linux xx-ThinkPad-X61 3.2.0-39-generic-pae #62-Ubuntu SMP Wed Feb 27 22:25:11 UTC 2013 i686 i686 i386 GNU/Linux

我遵循valgrind文件夹中README文件的安装说明。 ./configure - ＆gt; make - ＆gt; sudo make install。

我无法理解README文件中的以下提示，我只是忽略了它。

Important!  Do not move the valgrind installation into a place
different from that specified by --prefix at build time.  This will
cause things to break in subtle ways, mostly when Valgrind handles
fork/exec calls.

输入“valgrind ls -l”后，出现错误：

valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo

valgrind:  Cannot continue -- exiting now.  Sorry.

有人可以提出一些建议吗？

谢谢！

Answer 1

我也遇到了这个错误，但最终以下面的方式解决了。

我有64位Ubuntu 14.04，我的可执行文件是32位。当我用valgrind运行我的32位可执行文件时，我得到了同样的错误。即使在安装libc6-dbg（使用命令apt-get install libc6-dbg）后，此错误仍未解决。

后来我发现我机器中存在的libc6-dbg为64位，而valgrind需要32位libc6-dbg才能运行我的32位可执行文件。安装32位libc6-dbg后（使用命令apt-get install libc6-dbg:i386），它开始工作。

Answer 2

Valgrind表示它无法正常工作，因为它缺少libc调试信息，它表示必须安装哪个包来解决这个问题。在您的情况下（Ubuntu），您必须安装 libc6的-dbg的

Answer 3

apt install -y libc6-dbg

对我有用。（注意：无 :i386。）
直觉是自答案以来，Valgrind可能已升级到64位 rashok写的。
