That's definitely not going to work. You're trying to put make variable assignments inside a recipie. Make will try to execute a program called obj-m and then try to execute a program called modname-y. obj-m += modname.o outside a recipie is correct for kernel makefiles. > Make is not giving the error, I think it is the Kbuild system > determining that there is nothing to be done for your files because > there are no objects to be placed in your module. The documentation on > making makefiles for your projects is in Documentation/kbuild The Kbuild system is implemented using make. Make gives the error when it parses the makefile and decides that there is nothing to be done, i.e. all targets are up to date. The error is essentially saying that mydriver.o already exists and is newer than mydriver.c. It would help if you could copy and paste the exact error, along with all of the other output of running make. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
