我正在嘗試建置並安裝 Raspberry Pi RT Preempt Linux 核心。
這些是我遵循的步驟：
我安裝了預編譯的內核kernel-4.4.9-rt17.tgz
我下載了Raspberry Pi內核原始碼並應用了實時補丁-4.4.9-rt17.patch.gz。這個連結用於安裝）
我使用以下命令為 Raspberry Pi3、Model B 配置了核心：
export KERNEL=kernel7 make bcm2709_defconfig我使用以下命令將核心配置為支援完全搶佔式核心 (RT)
make -j$(nproc) menuconfig我使用建構內核
make -j$(nproc) zImage但我收到錯誤：
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
你有什麼辦法可以解決這個問題嗎？我不知道我做錯了什麼。我真的很感激任何幫助。
