That's not how you compile a Linux kernel module, sorry.
Please read the very good documentation for how to set up a Makefile for
building a kernel module. It's in the kernel's Documentation/
directory.

Kernel module compilation errors
I am just getting started with kernel module development, and I can't get
anything to compile.
I get the following errors:
In file included from main.c:1:0:
/usr/src/linux/include/linux/init.h:142:13: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘load_default_modules’
void __init load_default_modules(void);
^~~~
/usr/src/linux/include/linux/init.h:143:12: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘init_rootfs’
int __init init_rootfs(void);
^~~
/usr/src/linux/include/linux/init.h:285:13: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘parse_early_param’
void __init parse_early_param(void);
^
/usr/src/linux/include/linux/init.h:286:13: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘parse_early_options’
void __init parse_early_options(char *cmdline);
The errors go on and on, but the majority look like that.
My code:
#include
#include
int main() {
return 0;
}
The compile command:
gcc -I /usr/src/linux/include/ main.c
Thanks in advance for any help

Possible Sysfs for led class drivers
Hi, I have scanned through some of the led sysfs interfaces of my hardware boards inside the /sys/class/leds and found these brightness, max_brightness trigger uevent invert sata I want to know can we add our own custom sysfs interface ? Does there exists a default list of interfaces provided by the led class subsystem? like brightness, max_brightness,trigger,uevent ,etc?? Thanks in advance !
