Ubuntu12.04下使用valgrind内存测试工具测试Qt程序

1. 到官网http://valgrind.org/downloads/上下载valgrind最新版本；

2. 解压源码，执行./configure;make;make install后，默认安装到/usr/local/bin下，执行：

valgrind ls -l

3. 提示：

==== Command: ls -l

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-.so.
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux-x86-.so.
valgrind:
valgrind:  Possible fixes: (, short term): install glibc's debuginfo
valgrind:  package on this machine.  (, 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 () is called
valgrind:
valgrind:    On Debian, Ubuntu:                 libc6-dbg
valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
valgrind:
valgrind:  Cannot continue -- exiting now.  Sorry.

大概是说我的glibc是个strip后的版本，需要下载debug版，debug版的名字是libc6-dbg。

执行：

sudo apt-get install libc6-dbg

4. 再次执行valgrind ls -l，输出：

看来ls这个命令是没有任何内存问题的。。。
