Hello everybody. I'm trying to port some kernel modules which we used on
xeno2 to xeno3 cobalt.
The old code used the native skin so I'm trying to get it working using the
transaction kit (trank/native).
I've got some major differences between the two env though. The old xeno2
had some libraries included in itself which seem to me had been deprecated
in over OS standard ones.
This is my old makefile configuration:
$ make print-EXTRA_CFLAGS
EXTRA_CFLAGS =
-I/lib/modules/2.6.35.9-xenomai-2.5.6-acpi-3/build/include/xenomai
-I/lib/modules/2.6.35.9-xenomai-2.5.6-acpi-3/build/include/xenomai/posix
-I/root/iarte/include

My code sees errno.h because of this posix include path.
In the new configuration I can't compile because errno.h is not included:

I'm using Kernel 4.9.24 iPipe patched with xenomai 3.0.5 cobalt core.
Am I doing something wrong? How could I proceed?
Thanks in advance,
Simone
