valgrind检测linux程序内存泄露
1.可以在Valgrind Home下载最新版本；
2.解压之后，打开README文件，查看软件的安装方法，一般都是./configure make make install这三步；
3.检查是否安装正确：
1 valgrind ls -l
我安装的时候出现如下错误：
1 # valgrind ls -l 2 ==13544== Memcheck, a memory error detector 3 ==13544== Copyright (C) 2002-2012, and GNU GPL'd, by Julian Seward et al. 4 ==13544== Using Valgrind-3.8.1 and LibVEX; rerun with -h for copyright info 5 ==13544== Command: ls -l 6 ==13544== 7 8 valgrind: Fatal error at startup: a function redirection 9 valgrind: which is mandatory for this platform-tool combination 10 valgrind: cannot be set up. Details of the redirection are: 11 valgrind: 12 valgrind: A must-be-redirected function 13 valgrind: whose name matches the pattern: strlen 14 valgrind: in an object with soname matching: ld-linux.so.2 15 valgrind: was not found whilst processing 16 valgrind: symbols from the object with soname: ld-linux.so.2 17 valgrind: 18 valgrind: Possible fixes: (1, short term): install glibc's debuginfo 19 valgrind: package on this machine. (2, longer term): ask the packagers 20 valgrind: for your Linux distribution to please in future ship a non- 21 valgrind: stripped ld.so (or whatever the dynamic linker .so is called) 22 valgrind: that exports the above-named function using the standard 23 valgrind: calling conventions for this platform. The package you need 24 valgrind: to install for fix (1) is called 25 valgrind: 26 valgrind: On Debian, Ubuntu: libc6-dbg 27 valgrind: On SuSE, openSuSE, Fedora, RHEL: glibc-debuginfo 28 valgrind: 29 valgrind: Cannot continue -- exiting now. Sorry.
以上错误，是因为ubuntu还需要一个库：
1 sudo apt-get install libc6-dbg
安装完这个库之后再次运行valgrind ls -l
4.使用方式：
1 valgrind --tool=memcheck --leak-check=full ./main
