Что ж... попробуем добавить хедер asm/types.h перед включением
linux/videodev2.h (как это сделано в вашей программе):
[c0der@rock ~]$ gcc video-test.c -o video-test
In file included from video-test.c:2:
/usr/include/linux/videodev2.h:512: ошибка: поле 'timestamp' имеет неполный тип
А вот и ваша ошибка...
Структура timeval определена в файла sys/time.h (как написано в
setitimer(3)). Попробуем добавить этот хедер:
[c0der@rock ~]$ cat video-test.c
#include <asm/types.h>
#include <sys/time.h>
#include <linux/videodev2.h>
int main(void) {
return 0;
}
[c0der@rock ~]$ gcc video-test.c -o video-test
[c0der@rock ~]$
Вывод: хедер linux/videodev2.h использует структуры из других хедеров,
но их не подключает. Это баг. Можно повесить даже в багзиллу с
приведёнными тест-кейсами.
Workaround: добавить подключение sys/time.h вручную.
