求助：f1c100s vscode下驱动编写老是编译不过，

LinuxGo · 2021-01-21 17:13:09

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) chean

c_cpp_properties.json修改了如下

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "/home/jonsen/f1c100s/linux/include",
                "/home/jonsen/f1c100s/linux/arch/arm/include/",
                "/home/jonsen/f1c100s/linux/arch/arm/include/generated/"
            ],
            "defines": [],
            //"compilerPath": "/usr/bin/gcc",
            "compilerPath":"/home/jonsen/f1c100s/buildroot-2017.08/output/host/bin/arm-linux-gcc",
            "cStandard": "gnu17",
            "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
make[1]: Entering directory '/home/jonsen/f1c100s/linux'
make[1]: *** No rule to make target 'kernel_modules'. Stop.
make[1]: Leaving directory '/home/jonsen/f1c100s/linux'
make: *** [Makefile:8: kernel_modules] Error 2
不知怎么处理了，大佬们帮忙指指路。。。

把$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) kernel_modules
改成$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
试试

改后有变化，错误信息还是有，大佬再看下

armstrong 说：

把$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) kernel_modules
改成$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
试试

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) clean
