Hi Prassanna , do a grep on the file /proc/ksyms and fild where the occurunce of put_user occurs if it is there in the first place.If it is present in some other name and u are using RH9 then just rename the function call to that and maybe u have not included the correct include files.Many functions are #define d in the sources so pls be careful.Ok>Bye. --- prasanna wakhare <prasannawakhare@yahoo.com> wrote: > I'm compiling linux device driver's first simple > scull > module it is giving me error > > /scullc.o: unresolved symbol __PUT_USER > ./scullc.o: unresolved symbol __GET_USER > ./scullc.o: unresolved symbol copy_to_user > ./scullc.o: unresolved symbol copy_from_user > ./scullc.o: > > plz get me out of this? > > __________________________________ > Do you Yahoo!? > Yahoo!
