i am using the Kate editor that comes with kde.

well the good news is that the tab in front of default is gone now, and it tried to run the make command, but failed because MAKE is not defined.

do i explicitly need to define make,arent the things that i have done wth the makefile .
also the line i.e needed to make the module insertable i.e,
not there in the latest Makefile that i have used,as u said without using if and else loops.so wont that create a problem.

> do i explicitly need to define make
if you are going to use a variable (MAKE), you have to define it. in this case you probably want gcc right. so somewhere before its used say
MAKE=/path/to/gcc
then call it
$(MAKE) -C $(KDIR) ...
also its typically called CC, not make

i just took the ifneq() out to test, because i was getting a missing seperator error. the systax of the ifneq looks ok, but there must be something im missing with it. when i took it out i was able to run the makefile on my machine (it didnt do anything of course except tell me that it could not find those files, but it ran)

have you tried any other editors since posting? like i said i used the Kate editor, and i also used the Joe editor on this and it writes fine for me.
