valgrind 神器不用我多说，linux平台开发利器。
一、 安装
1. autoconf
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
# tar -zxvf autoconf-2.69.tar.gz
# cd autoconf-2.69
# ./configure
# make; make install
2. automake
# wget http://ftp.gnu.org/gnu/automake/automake-1.14.tar.gz
# tar -zxvf automake-1.14.tar.gz
# cd automake-1.14
# ./bootstrap.sh
# ./configure
# make; make install
3. valgrind
# wget http://valgrind.org/downloads/valgrind-3.11.0.tar.bz2
# tar -jxvf valgrind-3.11.0.tar.bz2
# cd valgrind-3.11.0
# ./autogen.sh
#./autogen.sh 缺少这步会导致failed to start tool 'memcheck' for platform 'amd64-linux'
修改configure脚本armv7*) 改为armv7* | arm )
arm-hisiv200-linux... 这些命令要在环境变量下哦，不用多说。
./configure --host=arm-linux CC=arm-none-linux-gnueabi-gcc CPP=arm-none-linux-gnueabi-cpp CXX=arm-none-linux-gnueabi-g++ --prefix=/home/dcj/valgrind
./configure \
--prefix="$PWD/install" \
CC=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-gcc \
CXX=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-g++ \
CPP=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-cpp \
AR=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-ar \
--target=aarch64-himix100-linux \
--host=aarch64-himix100-linux \
--program-prefix=hisi-
# sudo make
#sudo make install
–prefix=/home/dcj/valgrind指定的目录要与开发板上放置的目录一致，不然运行valgrind时可能会出现“valgrind: failed to start tool ‘memcheck’ for platform ‘arm-linux’: No such file or directory”错误。
解决方案：可以看到lib下面还有一层目录valgrind，这时候我们在开发板/etc/profile文件中添加一行
export VALGRIND_LIB=/opt/valgrind-3.12.0/lib/valgrind
可执行文件生成在源码路径
4. 将install/bin目录下的可执行文件hisi-valgrind拷贝到海思板子上，将install/lib目录下的valgrind目录也拷贝到海思板子上，此目录下包含了执行hisi-valgrind时需要的库，然后依次执行如下命令，结果如下图所示：
export VALGRIND_LIB=valgrind/
./hisi-valgrind --version
- 测试代码main.cpp如下：
#include <stdio.h>
#include <iostream>
namespace {
void func1() {
int* p1 = new int[10];
}
void func2() {
int* p2 = new int[5];
}
} // namespace
int main()
{
fprintf(stdout, "test start\n");
func1();
func2();
fprintf(stdout, "test finish\n");
}
- 执行如下命令，生成可执行文件main:
/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-g++ -g -o main main.cpp
7. 将可执行文件main拷贝到海思板子上，执行如下命令 ，结果如下图所示：
./hisi-valgrind --tool=memcheck --leak-check=full ./main

# Darwin gets identified as 32-bit even when it supports 64-bit.
# (Not sure why, possibly because 'uname' returns "i386"?) Just about
# all Macs support both 32-bit and 64-bit, so we just build both. If
# someone has a really old 32-bit only machine they can (hopefully?)
# build with --enable-only32bit. See bug 243362.
