1 编译

1.1下载

http://valgrind.org

1.2编译

#./configure --prefix=/home/work/third_party/valgrind/valgrind-3.16.1/__install --host=arm-linux CC=arm-linux-gnueabihf-gcc

然后打开configure文件，搜索armv7* 字段，将其改写为 armv7* |arm

#make
#make install

至此，已经完成了valgrind的编译工作。

2 运行

将生成的bin以及lib放到设备上，并设置valgrind的共享库，使用如下指令即可：

#export VALGRIND_LIB=/mnt/usb1/lib/valgrind/

/mnt/usb1/lib/valgrind/为设备存放valgrind 库的路径。

使用如下指令运行valgrind:

#/mnt/usb1/valgrind --tool=memcheck --leak-check=full test_bin

如果出现如下的指令，则说明我们使用的glibc的库不匹配，需要重新交叉编译glibc，然后使用新的glibc库。

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:      index
valgrind:  in an object with soname matching:   ld-linux-armhf.so.3
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname: ld-linux-armhf.so.3
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:  to install for fix (1) is called
valgrind:  
valgrind:    On Debian, Ubuntu:                 libc6-dbg
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:  package (e.g. libc6-dbg:i386).
valgrind:  
valgrind:  Cannot continue -- exiting now.  Sorry.

交叉编译的glibc最好要和文件系统中原有的glibc库版本一致，并且使用-g选项进行交叉编译，将编译后的库替换到文件系统中去。
