[Xenomai] integrated drivers not built?

[Xenomai] integrated drivers not built?

[Kronander Klas]

Hello,

Is there some special configuration that must be set in order to build the integrated drivers (specifically the can-related ones)?

I built xenomai, but I am not able to load any of the drivers. When looking in /lib/modules/[MYKERNEL]/ folder, I find the drivers listed in modules.builtin:

cat /lib/modules/[MYKERNEL]/modules.builtin | grep xeno

kernel/kernel/xenomai/nucleus/xeno_nucleus.ko
kernel/kernel/xenomai/skins/native/xeno_native.ko
kernel/kernel/xenomai/skins/posix/xeno_posix.ko
kernel/kernel/xenomai/skins/rtdm/xeno_rtdm.ko
kernel/drivers/xenomai/can/xeno_can.ko
kernel/drivers/xenomai/can/sja1000/xeno_can_sja1000.ko
kernel/drivers/xenomai/can/sja1000/xeno_can_peak_pci.ko
kernel/drivers/xenomai/serial/xeno_16550A.ko
kernel/drivers/xenomai/testing/xeno_timerbench.ko
kernel/drivers/xenomai/testing/xeno_switchtest.ko

but I can't find any of these object files on the paths specified in the moduels.builtin file.  There is no xenomai directory in /lib/modules/[MYKERNEL]/kernel/drivers, which I believe there should be?

Are the modules even built, and if so, where are they? I built xenomai using:
cd /usr/src/xenomai-2.5.5.2
sudo ./configure --enable-dlopen-skins
sudo make
sudo make install

I hope someone can clarify this, thanks in advance

All modules named xeno_* are xenomai modules.

Xenomai 2.5.5.2 is doubly outdated:
- it is not the latest stable release in the 2.5 branch;
- 2.5 is not the latest stable branch, 2.6 is.

Sorry, I misunderstood the question. You want to know how to build and
install modules. I suggest you read:
