Valgrind移植与使用教程
源码版本：valgrind-3.16.1.tar.bz2
ubutun版本：20.04
交叉编译链：arm-none-linux-gnueabi-
交叉编译命令介绍：
| configure配置说明 | 说明 |
|---|---|
| –build | 执行代码编译的主机 |
| –host | 程序最终要运行的主机 |
| –target | 用build主机上的编译器，编译一个新的编译器（ 如gcc），这个新的编译器将来编译出来的其他程序将运行在target指定的系统上 |
| –prefix | 指定编译出来的版本存放路径，默认放在“/usr /local/bin” |
| CC CXX CPP | 交叉编译器配置CC=arm-none-linux-gnueabi-cc CPP=arm-none-linux-gnueabi-cpp CXX=arm-none-linux-gnueabi-g++ |
安装步骤：
编译linux版本
1.解压并运行valgrind自动make脚本
vmuser@vmuser-virtual-machine:tar jxvf valgrind-3.16.1.tar.bz2
vmuser@vmuser-virtual-machine:~/valgrind-3.16.1$ sudo apt-get install automake
vmuser@vmuser-virtual-machine:~/valgrind-3.16.1$ ./autogen.sh
2.configure
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ mkdir install
vmuser@vmuser-virtual-machine:~/valgrind-3.16.1$ ./configure --prefix=/home/vmuser/valgrind-3.16.1/install/
3.make
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ make
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ make install
编译ARM版本
1.编译之前先make clean
2.修改 configure 文件：
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ mkdir install_arm
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ ./configure --host=arm-linux CC=arm-none-linux-gnueabi-cc CPP=arm-none-linux-gnueabi-cpp CXX=arm-none-linux-gnueabi-g++ --prefix= --prefix=/home/vmuser/valgrind-3.16.1/install_arm/
报错
checking host system type... arm-unknown-linux-gnu
checking for a supported CPU... no (arm)
configure: error: Unsupported host architecture. Sorry
修改configure 把armv7a* 改为 arm* 再次配置configure
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ ./configure --host=arm-linux CC=arm-none-linux-gnueabi-cc CPP=arm-none-linux-gnueabi-cpp CXX=arm-none-linux-gnueabi-g++ --prefix= --prefix=/home/vmuser/valgrind-3.16.1/install_arm/
//注意：–prefix=/mnt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。
3.编译安装
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ make
vmuser@vmuser-virtual-machine:~/valgrimakend-3.16.1$ make install
4.移植到arm开发板
将/home/vmuser/valgrind-3.16.1/install_arm/目前下文件复制到arm同级目录下；
将/home/vmuser/valgrind-3.16.1/install_arm/bin/valgrind文件复制到/bin目录下。
root@freescale /home/vmuser/valgrind-3.16.1$ valgrind --help
usage: valgrind [options] prog-and-args
tool-selection option, with default in [ ]:
--tool=<name> use the Valgrind tool named <name> [memcheck]
basic user options for all Valgrind tools, with defaults in [ ]:
-h --help show this message
--help-debug show this message, plus debugging options
--help-dyn-options show the dynamically changeable options
--version show version
-q --quiet run silently; only print error msgs
-v --verbose be more verbose -- show misc extra info
--trace-children=no|yes Valgrind-ise child processes (follow execve)? [no]
--trace-children-skip=patt1,patt2,... specifies a list of executables
that --trace-children=yes should not trace into
--trace-children-skip-by-arg=patt1,patt2,... same as --trace-children-skip=
but check the argv[] entries for children, rather
than the exe name, to make a follow/no-follow decision
--child-silent-after-fork=no|yes omit child output between fork & exec? [no]
--vgdb=no|yes|full activate gdbserver? [yes]
full is slower but provides precise watchpoint/step
--vgdb-error=<number> invoke gdbserver after <number> e
