zasto da include-va types.h ? koq function ste polzva ot tam ... ??? Za da
kompilira tazi programa koqto e napisal mozhe nisto da ne include-va, ama
nisto. No posle kato izpylni "insmod hello.o" ste mu kazhe 4e ne mozhe da
poznae za koq versiq na kernela e bil kompiliran tozi module, tova e ako ima
kernel compiled s CONFIG_MODVERSION. Za tova ostava da include-va samo
"module.h" i kompilira kakto kaza Angel.

Zna4i tova e nqkakva stara distrubuciq bazirana na kernel 2.0 ili 2.2 i v
prehod ot libc5 kym libc6 (glibc 2) ili ti si si kompiliral sam glibc i
linuxthreads i nqkude v stari docs si pro4el za tezi symlinks ot /usr/include
kym /usr/src/linux. Tova ne go pishe v docs na glibc, nito pyk v docs na
linuxthreads !!! Ta:
glibc 2 ne bi trqbvalo da imash symlinks
ot /usr/include kym /usr/src/linux.
A v /usr/src/linux/include/ syotvetno "asm" e symlink kym asm-<arch>, i tova
e edinstveniq symlink v kernel source, kato arch se opredelq build time, da
se znae za kakva arhitektura se kompilira kernela i da se vklu4i syotvetniq
asm kod, koito e machinno zavisim. Tova e.
