I don't even pretend to understand this, but think it probably needs to be seen by someone who does. The aim is to suppress some error messages that are produced when compiling with "comp"

My proposal for getting out of this sandpit ist following: 1.) the emc2 modules do not have a Modules.symvers file. This file holds the dependencies of extern defined functions. 2.) the rtai modules do have this file. So to get it work to check dependencies to avoid the above mentioned warnings, we must have a Modules.symvers file too for emc modules. This is a little more work to do. And when we want to do it, then we should correct the whole things for modules, like not living in standard kernel trees. Advice from kernel.org is to use /lib/modules/kernel-vers/extra/rtai and ../emc My proposal is to use /lib/modules/kernel-vers/extra/emc /lib/modules/kernel-vers/extra/rtai The next point is, if we do so: The kernel Makefile syntax for external modules was changed, this is not dramatically but we can write it shorter in our template. New line for rtai modules would be: $(MAKE) -C $(KERNELDIR) M=$(RTAIMOD) O=$(RTAIMOD) with RTAIMOD := /lib/modules/linux-2.6.32-122-rtai/modules/extra/rtai KERNELDIR := /usr/src/linux-headers-2-6-32-rtai and for emc modules: $(MAKE) -C $(KERNELDIR) M=$(EMCMOD) O=$(EMCMOD) with EMCMOD := /lib/modules/linux-2.6.32-122-rtai/modules/extra/emc KERNELDIR := /usr/src/linux-headers-2-6-32-rtai If we do it in this way, the O=.... can be omitted. In former times you have to use KERNEL_EXTMOD Variable for something like that. Or, if do NOT want this, we should generate at least the Modules.symvers file for emc modules.
