我正在尝试构建并安装 Raspberry Pi RT Preempt Linux 内核。
这些是我遵循的步骤：
我安装了预编译的内核kernel-4.4.9-rt17.tgz
我下载了Raspberry Pi内核源代码并应用了实时补丁-4.4.9-rt17.patch.gz。（我遵循这个链接用于安装）
我使用以下命令为 Raspberry Pi3、Model B 配置了内核：
export KERNEL=kernel7 make bcm2709_defconfig我使用以下命令将内核配置为支持完全抢占式内核 (RT)
make -j$(nproc) menuconfig我使用构建内核
make -j$(nproc) zImage但我收到错误：
In file included from arch/arm/kernel/asm-offsets.c:14:0: ./include/linux/sched.h:2040:32: error: expected identifier or ‘(’ before ‘&’ token define tsk_cpus_allowed(tsk) (&(tsk)->cpus_allowed) ^ ./include/linux/sched.h:3679:37: note: in expansion of macro ‘tsk_cpus_allowed’ static inline const struct cpumask *tsk_cpus_allowed(struct task_struct *p) ^ In file included from arch/arm/kernel/asm-offsets.c:14:0: ./include/linux/sched.h:3687:19: error: redefinition of ‘tsk_nr_cpus_allowed’ static inline int tsk_nr_cpus_allowed(struct task_struct *p) ^ In file included from arch/arm/kernel/asm-offsets.c:14:0: ./include/linux/sched.h:2042:19: note: previous definition of ‘tsk_nr_cpus_allowed’ was here
你有什么办法解决这个问题吗？我不知道我做错了什么。我真的很感激任何帮助。
