Linux Kernel - Data definition has no type or storage class -


i working on linux kernel 3.4, , have following code:

    /* proximity sensor calibration values */ unsigned int als_kadc; export_symbol(als_kadc); static int __init parse_tag_als_calibration(const struct tag *tag) {     als_kadc = tag->u.als_kadc.kadc;      return 0; }  __tagtable(atag_als, parse_tag_als_calibration);

but when build it, gives me following error:

warning: data definition has no type or storage class [enabled default]

yes, warning, forbidden warning, , being treated error. warning point following line in code:

export_symbol(als_kadc);

can me solve problem?

thank you.

ok. figured out problem: missing include module.h

so, added code file:

#include <linux/module.h>

this fixed problem, because export_symbol defined in header file.
