ubuntu13.04安装使用systemtap

添加包含dbgsym版本包的源:

    为12.04添加apt-get源： 
    deb http://ddebs.ubuntu.com/ precise          main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ precise-security main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ precise-updates  main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ precise-proposed main restricted universe multiverse 
    
    为12.10添加apt-get源： 
    deb http://ddebs.ubuntu.com/ quantal          main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ quantal-security main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ quantal-updates  main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ quantal-proposed main restricted universe multiverse 
    
    为13.04添加apt-get源： 
    sudo tee /etc/apt/sources.list.d/ddebs.list << EOF 
    deb http://ddebs.ubuntu.com/ raring          main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ raring-security main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ raring-updates  main restricted universe multiverse 
    deb http://ddebs.ubuntu.com/ raring-proposed main restricted universe multiverse 
    
    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ECDCAD72428D7C01 
    sudo apt-get update 

安装内核

    sudo apt-get install linux-image-$(uname -r)-dbgsym

安装systemtap

sudo apt-get install systemtap

使用

准备一个简单的c程序:

  void hello(int r)
  {
  	int haha = 100;
  	printf("kljasldjfksajdkfjds\n");
  }
    
  int main(int argc,void* argv)
  {
  	while(1){
  		hello(23423423);
  		sleep(1);
  	}
  	exit(0);
  }

带debug 编译:
```
  gcc -g hello.c
```

运行:

  stap -e 'probe process("a.out").function("*")
  {
    printf("%s(%d) %s(%s)\n", execname(), pid(),ppfunc(), $$parms$$)
  }' -c '/home/liangwei/a.out'

结果:

  kljasldjfksajdkfjds
  a.out(23959) main(argc=0x0 argv=0x7fff5b4ed450)
  a.out(23959) hello(r=0x0)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x0)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
  kljasldjfksajdkfjds
  a.out(23959) hello(r=0x16569bf)
