（Ubuntu64）valgrind安装+编译64位 32位版本

安装编译步骤：

wget http://valgrind.org/downloads/valgrind-3.12.0.tar.bz2

 

tar xvf valgrind-3.12.0.tar.bz2

 

cd valgrind-3.12.0

 

sudo apt-get install automake

 

./autogen.sh

 

./configure --prefix=/<pathto>/valgrind-3.12.0

 

make

 

make install

 

添加至环境变量：

sudo gedit ~/.bashrc

添加：

export PATH=$PATH:/<pathto>/valgrind-3.12.0/bin

export VALGRIND_LIB="/<pathto>/valgrind-3.12.0/lib/valgrind"

source .bashrc

检测是否成功编译：

valgrind --version

测试用例：

#include <stdlib.h>

int main()

{

int * pArray =malloc(sizeof(int) * 5);

pArray[5] = 1;

int * pInt ;

int x = *pInt;

* pInt = 2;

return 0;

}

编译：gcc -g -o test main.c

检测：valgrind --leak-check=yes ./test

检测32位程序的时候需要安装对应的i386库否则会提示错误：

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.so.2
valgrind:  was not found whilst processing

valgrind:  
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, 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:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
valgrind:  
valgrind:  Note that if you are debugging a 32 bit process on a
valgrind:  64 bit system, you will need a corresponding 32 bit debuginfo

valgrind:  Cannot continue -- exiting now.  Sorry.

安装对应的i386库：sudo apt-get install  libc6-dbg:i386=2.23-0ubuntu10
