标签:linux 云服务器 valgrind 内存泄露 内存越界
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。
