Linux下安装Valgrind工具

 

valgrind是一款很优秀的内存泄漏检测工具。

 

下面介绍如何在Linux下安装Valgrind。

 

首先下载安装包到/root目录下（或者其他目录）；

 

[root@localhost ~]# lltotal 7200-rw-------. 1 root root    2692 Apr 10 13:52 anaconda-ks.cfg-rw-r--r--. 1 root root   39935 Apr 10 13:52 install.log-rw-r--r--. 1 root root    9154 Apr 10 13:51 install.log.syslog-rw-r--r--. 1 root root  303586 Apr 11 22:50 lua-5.3.4.tar.gz-rw-r--r--. 1 root root 6998648 Apr 11 19:34 ntp-4.2.8p10.tar.gzdrwxr-xr-x. 2 root root    4096 Apr 12 18:57 sort[root@localhost ~]# which valgrind/usr/bin/which: no valgrind in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)[root@localhost ~]# cd /usr/local/src/[root@localhost src]# ll /root/total 19692-rw-------. 1 root root     2692 Apr 10 13:52 anaconda-ks.cfg-rw-r--r--. 1 root root    39935 Apr 10 13:52 install.log-rw-r--r--. 1 root root     9154 Apr 10 13:51 install.log.syslog-rw-r--r--. 1 root root   303586 Apr 11 22:50 lua-5.3.4.tar.gz-rw-r--r--. 1 root root  6998648 Apr 11 19:34 ntp-4.2.8p10.tar.gzdrwxr-xr-x. 2 root root     4096 Apr 12 18:57 sort-rw-r--r--. 1 root root 12788556 Apr 14 17:56 valgrind-3.12.0.tar.bz2[root@localhost src]# tar jxf /root/valgrind-3.12.0.tar.bz2 [root@localhost src]# lltotal 12drwxr-xr-x.  4 1026 1000 4096 Apr 11 23:02 lua-5.3.4drwxrwsr-x. 23  427 6011 4096 Mar 21 07:47 ntp-4.2.8p10drwxrwxr-x. 24 1000 1000 4096 Oct 21 04:03 valgrind-3.12.0[root@localhost src]# cd valgrind-3.12.0/[root@localhost valgrind-3.12.0]# lltotal 1996-rw-rw-r--.  1 1000 1000  44566 Oct 21 03:42 aclocal.m4-rw-rw-r--.  1 1000 1000   3267 Oct 21 03:37 AUTHORS-rwxrwxr-x.  1 1000 1000    191 Oct 21 03:37 autogen.shdrwxrwxr-x.  3 1000 1000   4096 Oct 21 04:01 auxprogs

将源码解压缩到/usr/local/src下。

 

阅读下valgrind中的README文件，可以看到如下信息：

 

Building and installing it

~~~~~~~~~~~~~~~~~~~~~~~~~~ To install from the Subversion repository :

  0. Check out the code from SVN, following the instructions at

     http://www.valgrind.org/downloads/repository.html.

  1. cd into the source directory.

  2. Run ./autogen.sh to setup the environment (you need the standard

     autoconf tools to do so). 

  3. Continue with the following instructions...

To install from a tar.bz2 distribution:

  4. Run ./configure, with some options if you wish.  The only interesting

     one is the usual --prefix=/where/you/want/it/installed.

  5. Run "make". 

  6. Run "make install", possibly as root if the destination permissions

     require that.

  7. See if it works.  Try "valgrind ls -l".  Either this works, or it

     bombs out with some complaint.  In that case, please let us know      (see www.valgrind.org).

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.

 

和通常的安装步骤一样：configure；make；make install

 

过程如下：

 

[root@localhost valgrind-3.12.0]# ./configure --prefix=/usr/local/valgrind

checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes …… config.status: executing depfiles commands

make install后发现还是没有（没有找到）valgrind可执行文件。

 

其实这个时候已经有了，只是没有找到罢了。

 

我们可以将valgrind做一个软连接到/usr/local/bin下：

 

[root@localhost local]# cd valgrind/ [root@localhost valgrind]# ll total 16 drwxr-xr-x. 2 root root 4096 Apr 14 18:04 bin drwxr-xr-x. 3 root root 4096 Apr 14 18:04 include drwxr-xr-x. 4 root root 4096 Apr 14 18:04 lib drwxr-xr-x. 4 root root 4096 Apr 14 18:04 share [root@localhost valgrind]# cd bin/ [root@localhost bin]# ll total 392 -rwxr-xr-x. 1 root root 41112 Apr 14 18:04 callgrind_annotate -rwxr-xr-x. 1 root root 12016 Apr 14 18:04 callgrind_control -rwxr-xr-x. 1 root root 32170 Apr 14 18:04 cg_annotate -rwxr-xr-x. 1 root root 10418 Apr 14 18:04 cg_diff -rwxr-xr-x. 1 root root 49307 Apr 14 18:04 cg_merge -rwxr-xr-x. 1 root root 24398 Apr 14 18:04 ms_print -rwxr-xr-x. 1 root root 39093 Apr 14 18:04 valgrind -rwxr-xr-x. 1 root root 65697 Apr 14 18:04 valgrind-di-server -rwxr-xr-x. 1 root root 21037 Apr 14 18:04 valgrind-listener -rwxr-xr-x. 1 root root 85247 Apr 14 18:04 vgdb [root@localhost bin]# which valgrind /usr/bin/which: no valgrind in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin) [root@localhost bin]# cd /usr/local/bin/ [root@localhost bin]# ln -s /usr/local/valgrind/bin/valgrind valgrind [root@localhost bin]# which valgrind /usr/local/bin/valgrind

测试下：

 

[root@localhost bin]# valgrind ls -l ==16148== Memcheck, a memory error detector ==16148== Copyright (C) 2002-2015, and GNU GPL'd, by Julian Seward et al. ==16148== Using Valgrind-3.12.0 and LibVEX; rerun with -h for copyright info ==16148== Command: ls -l ==16148==  total 0 lrwxrwxrwx. 1 root root 32 Apr 14 18:06 valgrind -> /usr/local/valgrind/bin/valgrind ==16148==  ==16148== HEAP SUMMARY: ==16148==     in use at exit: 13,069 bytes in 11 blocks ==16148==   total heap usage: 206 allocs, 195 frees, 62,575 bytes allocated ==16148==  ==16148== LEAK SUMMARY: ==16148==    definitely lost: 0 bytes in 0 blocks ==16148==    indirectly lost: 0 bytes in 0 blocks ==16148==      possibly lost: 0 bytes in 0 blocks ==16148==    still reachable: 13,069 bytes in 11 blocks ==16148==         suppressed: 0 bytes in 0 blocks ==16148== Rerun with --leak-check=full to see details of leaked memory ==16148==  ==16148== For counts of detected and suppressed errors, rerun with: -v ==16148== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 21 from 10)

OK，安装完成。

 

回想刚刚的安装步骤：

 

1.解压源代码到/usr/local/src下；

2.configure --prefix=/usr/local/valgrind；

3.make && make install；

4.ln做一个软连接到/usr/local/bin中；

 

大功告成。
