Hi,

When building an external module, for example, given this command,
all:
    $(MAKE) -C $(KDIR) M=$$PWD

It will build the ko file in the $PWD.

How to specify a location for the .ko files?


Regards.

Perhaps KBUILD_EXTMOD is what you're looking for.

/path/to/kernel/sources/Makefile:183,185
# Use make M=dir to specify directory of external module to build
# Old syntax make ... SUBDIRS=$PWD is still supported
# Setting the environment variable KBUILD_EXTMOD take precedence
