1. 下载最新的valgrind，一般是首页里直接下载即可。
3.
Oracle VM VirtualBox虚拟机启动fedora系统（最好用root登录，不行也要在终端中输入sudo -s成为超级用户）。
4.虚拟机加载共享文件夹进入命令行,mount -t vboxsf sharefile /mnt,即将共享文件夹挂载到了/mnt。
5.在fedora系统中，启动资源管理器，找到File System下面的mnt文件夹，拷贝其中的文件到UserHD下面（为交叉编译做准备，目录可以改）
6.命令行 cd /media/UserHD/valgrind-3.10.1
./autogen.sh
./configure
--host=arm-linux CC=arm-none-linux-gnueabi-gcc CPP=arm-none-linux-gnueabi-cpp
CXX=arm-none-linux-gnueabi-g++ --prefix=/mnt/sdcard/valgrind
make
make install
7.到/mnt/sdcard/valgrind中去查看生成好的valgrind,其包括4个文件夹:bin,include,lib,share.
8.拷贝/mnt/sdcard/valgrind文件夹到arm板的相同路径下，运行即可。
目前valgrind工具实现了交叉编译，但在使用时还有问题。
我编译后，发现无问题，并且发现生成了目标代码与/mnt/sdcard/valgrind中。
但是我在make后通过make check却发现有问题。显示如下：

由于make结束后没有报错，我即认为虽有错误但不至于影响使用，遂将代码拷贝到arm开发板中去，但执行出错，显示: "Illegal instruction."

以上使用strace分析得到的结果，应该是CPU配置的问题，但是还没有解决。
