错误的android内核编译

我试图编译三星Galaxy迷你的Android内核（氰），根据这些instructions：错误的android内核编译

我使用CM-7。

我完成以下步骤：

下载内核源代码。

配置构建：

adb pull /proc/config.gz /home/user_name/android/kernel/cm-kernel/config.gz 
cat config.gz | gunzip > .config 
make ARCH=arm CROSS_COMPILE=$CCOMPILER menuconfig

使构建：

make ARCH=arm CROSS_COMPILE=$CCOMPILER -j4

后这个内核开始编译，一切工作正常，但随后报告这似乎是一个错误源代码中的错误，这里是终端中的输出。

如果有人可以请告诉如何解决此问题。

为什么不看内核/ cpuset.c源代码并试图找出它？可能在其他翻译单元中定义了“任务”，并且由于某种原因该单元未被包括（即，预处理器定义没有被正确配置）。 – Adi 2012-03-09 19:47:41

是的，我只是检查了内核/ cpuset.c并发现错误，基本上任务被错误定义（任务变量不存在），它应该是'tsk'。我在答案中解释了这个问题。无论如何，谢谢。 – uyaseen 2012-03-10 05:58:11

有没有在源代码中的错误，该文件中，核心/上线1385 cpuset.c ，使用“任务”，在那里，它应该是“啧啧”，而且后来被使用，而不被分配价值。它应该以这种方式分配值：__task_cred（tsk）。

这是原来的代码：

/* Called by cgroups to determine if a cpuset is usable; cgroup_mutex held */ 
static int cpuset_can_attach(struct cgroup_subsys *ss, struct cgroup *cont, 
      struct task_struct *tsk, bool threadgroup) 
{ 
int ret; 
struct cpuset *cs = cgroup_cs(cont); 

if ((current != task) && (!capable(CAP_SYS_ADMIN))) { 
    const struct cred *cred = current_cred(), *tcred; 

    if (cred->euid != tcred->uid && cred->euid != tcred->suid) 
     return -EPERM; 
}

......................

这是修改后的代码：

/* Called by cgroups to determine if a cpuset is usable; cgroup_mutex held */ 
static int cpuset_can_attach(struct cgroup_subsys *ss, struct cgroup *cont, 
      struct task_struct *tsk, bool threadgroup) 
{ 
int ret; 
struct cpuset *cs = cgroup_cs(cont); 

if ((current != tsk) && (!capable(CAP_SYS_ADMIN))) { 
    const struct cred *cred = current_cred(), *tcred; 
    tcred = __task_cred(tsk); 

    if (cred->euid != tcred->uid && cred->euid != tcred->suid) 
     return -EPERM; 
}

这个link解释了在android内核编译时可能发生的不同可能的错误。
