Hello Sam,
Thanks for reply.
Actually Problem is.
As I told you I have near near about 1000 file that
compiles for single module creation which spread in
multiple directies in 2.4 with lots of makefile.
Now I have created single makefile to compile all this
file and able to create kernel module.
But now the problem is lots of file included in kernel
module, compiled twice or even more then twice for
user space (whithou kernel flag set) and kernel space
as well.
Previously in 2.4 we use to put all output object file
in different directories for kernel module and user
binaries based on their compilation Flags.
Now after attaching kbuild makefile with this system,
kbuild make all object file in source directory itself
becasue of that userspace makefiles not able to
compile those file again. Because one object file is
already there by kbuild. So I am not able create
userspace binary.
Now either solution is generate kbuild object file in
different directory not in source directory as per our
previous design or make a copy of exsisting file with
some other name. One for kernel and one for user
space but this is also not a good approach.
So I thought lets check the possibility of generating
all kernel related object file in some other directory
not in source directory.
So I just want to know whether it is possible or not
and if possible how.
Thanks
