hisi3531 valgrind 交叉编译移植
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
#include namespace {void func1() {int* p1 = new int[10];
}void func2() {int* p2 = new int[5];
}} // namespaceint 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

# Platform variants?
#----------------------------------------------------------------------------# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control. The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm,mips}-linux, but not quite. So this introduces the concept of
# platform variant tags, which get passed in the compile as
# -DVGPV___ along with the main -DVGP__ definition.
#
# In almost all cases, the bit is "vanilla". But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
# -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
# -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.# In the normal case ..

# these packages. All regression test programs all compiled only
# for the primary target. And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary). Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
