LBC2第一次上电编译驱动报错——/bin/sh: 1: scripts/basic/fixdep: ...

renzhaomu

编译的makefile文件：

KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
obj-m := hello.o
all:
    $(MAKE) -C $(KERNELDIR) M=$(PWD) modules
clean:
    $(MAKE) -C $(KERNELDIR) M=$(PWD) clean
编译时报错：

make -C /lib/modules/4.19.232/build M=/home/cat/Desktop/Linux_BSP/1_hello_world modules
make[1]: Entering directory '/usr/src/linux-headers-4.19.232'
CC [M] /home/cat/Desktop/Linux_BSP/1_hello_world/hello_world.o
/bin/sh: 1: scripts/basic/fixdep: Exec format error
make[2]: *** [scripts/Makefile.build:340: /home/cat/Desktop/Linux_BSP/1_hello_world/hello_world.o] Error 2

make[1]: Leaving directory '/usr/src/linux-headers-4.19.232'
make: *** [Makefile:7: all] Error 2

主要报错：/bin/sh: 1: scripts/basic/fixdep: Exec format error
file scripts/basic/fixdep该文件发现该文件为x86文件，但是LBC2为aarch64类型。
解决方法：
cd到/usr/src/linux-headers-4.19.232/scripts/basic目录下执行gcc fixdep，
重新编译该文件为aarch64类型
再次执行make编译
报错：
make -C /lib/modules/4.19.232/build  M=/home/cat/Deskto/Linux_BSP/1_hello_world modules
make[1]: Entering directory

CC[M]  /home/cat/Desktop/Linux_BSP/1_hello_world/hello_world.o
  Building modules, stage 2.
  MODPOST 1 modules
/bin/sh: 1: scripts/mod/modpost: Execformat error
make[2]: *** [scripts/Makefile.modpost:108:__modpost] Error 2
make[1]: *** [Makefile:1680: modules] Error2
make[1]: Leaving directory

make: *** [Makefile:7: all] Error 2
同样的cd到/usr/src/linux-headers-4.19.232/scripts/mod目录下
执行gcc -o modpost modpost.c file2alias.c sumversion.c -I. -I..

再次编译无报错
/bin/sh: 1: ./scripts/recordmcount: Exec format error同样的原因cd到/usr/src/linux-headers-4.19.232/scripts目录下编译gcc -o recordmcount recordmcount.c再次make编译报错
