1. 到官網http://valgrind.org/downloads/上下載下傳valgrind最新版本；
2. 解壓源碼，執行./configure;make;make install後，預設安裝到/usr/local/bin下，執行：
valgrind ls -l 3. 提示：

==14336== Command: ls -l
==14336==
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: Cannot continue -- exiting now. Sorry. 大概是說我的glibc是個strip後的版本，需要下載下傳debug版，debug版的名字是libc6-dbg。
執行：
sudo apt-get install libc6-dbg 4. 再次執行valgrind ls -l，輸出：
