linux安装valgrind

       最近服务器程序出了一个崩溃，确定是内存地址访问越界，但是不能定位在哪里，没办法只好用valgrind来跑一下，以前公司的服务器是上都默认安装了，突然发现云服务器上没有安装这个软件，所以记录一下如何安装。

       1、下载最新版本的valgrind:
       http://www.valgrind.org/downloads/valgrind-3.9.0.tar.bz2
解压安装包：tar –jxvf valgrind-3.9.0.tar.bz2，解压后生成目录valgrind-3.9.0。

      目前支持的平台，在官网上列表如下：
      {x86,amd64,arm,ppc32,ppc64,s390x,mips32,mips64}-linux, arm-android (2.3 and later), x86-android (4.0 and later) and {x86,amd64}-darwin (Mac OS X 10.7, with limited support for 10。

      2、安装前配置编译选项，所以配置如下：

      # cd valgrind-3.9.0

      # ./autogen.sh

      # ./configure --prefix=/home/valgrind/bin

      3、编译和安装valgrind

      # make

      # make install

      4、到这来已经安装成功了，但还不能直接使用，需要创建一个软连接。

      # cd /usr/bin/

      # ln -s /home/valgrind/bin/bin/valgrind valgrind

      最后我们测试一下吧，如果运行so文件失败，可能需要设置库目录。

      # export LD_LIBRARY_PATH=`pwd`      

      # valgrind ./WorldFrame_d -c 2

      然后看看终端的显示，确定是否正确安装。
