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 <linux/init.h>
#include <linux/module.h>
int main() {
return 0;
}
The compile command:
gcc -I /usr/src/linux/include/ main.c
Thanks in advance for any help
