按照正点原子的驱动教程 在vscode下写了如下代码
#include <linux/module.h>
static int __init chardevbase_init(void)
{
return 0;
}
static void __exit chardevbase_exit(void)
{
;
}
module_init(chardevbase_init);
module_exit(chardevbase_exit);在Makefile里写了
KERNELDIR := /home/jonsen/f1c100s/linux
CURRENT_PATH := $(shell pwd)
obj-m := chrdevbase.o
build:kernel_modules
kernel_modules:
$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) kernel_modules
Clean:
$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) cheanc_cpp_properties.json修改了如下
{
"configurations": [

"cppStandard": "gnu++14",
"intelliSenseMode": "gcc-x64"
}
],
"version": 4
}make 后
出现 ：
jonsen@ubuntu:~/f1c100s/test_chrdevbase$ make
make -C /home/jonsen/f1c100s/linux M=/home/jonsen/f1c100s/test_chrdevbase kernel_modules

不知怎么处理了，大佬们 帮忙指指路。。。
最近编辑记录 LinuxGo (2021-01-21 17:17:18)

改后有变化，错误信息还是有，大佬再看下

make: *** [Makefile:8: kernel_modules] Error 2把$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) kernel_modules
改成$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules

感谢大佬，
目前写成了,顺利编译
KERNELDIR := /home/jonsen/f1c100s/linux/
CURRENT_PATH := $(shell pwd)
CROSS_COMPILE:= /home/jonsen/f1c100s/buildroot-2017.08/output/host/bin/arm-linux-
ARCH = arm
obj-m := chardevbase.o
build: kernel_modules
kernel_modules:
$(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
clean:
$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) cleanARCH=arm
#当前目录
CUR_DIR = $(shell pwd)
#源码目录
KERNEL_DIR = /home/jonsen/f1c100s/linux
#交叉编译工具链
CROSS_COMPILE = arm-linux-gnueabihf-
#模块名字
MODULE_NAME = chrdevbaseifeq ($(KERNELRELEASE),)
all:
make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_DIR) M=$(CUR_DIR) modules
clean:
#清除模块
make -C $(KERNEL_DIR) M=$(CUR_DIR) clean
else
obj-m+=$(MODULE_NAME).oendif
试试这个
