Hello everybody,
thanks to your previous hints I've succesfully got Cobalt working.
I'm trying to compile some (previously coded for Xenomai 2) code.
I'm facing an odd issue which I don't think is related to Xenomai but
rather to
the way my Makefile is built.
I'd be real grateful to anybody out there willing to help me because I'm
no make
file expert at all.
It seems that gcc doesn't include standard include paths for no reasons
apperant
ly through my makefile.
I'm working on Debian 9.
Here's the include paths of gcc:
gcc -xc -E -v -
Using built-in specs.

When I run make this is what happens:

If I explicit the (standard?) include path over gcc into make, adding
"-I/usr/in
clude/x86_64-linux-gnu" at the end of EXTRA_CFLAGS, I get this behaviour:
make -C /lib/modules/4.9.24-ipipe-xenomai-3.0.5-cobalt/build

Of course I do have libcv-dev installed and everything is in the right
place:
ls -l /usr/include/x86_64-linux-gnu/sys/types.h
-rw-r--r-- 1 root root 6687 Jun 15 21:17

ypes.h
ls -l /usr/include/features.h
-rw-r--r-- 1 root root 13069 Jun 15 21:17 /usr/include/features.h
Hope anybody out there could/will help me :)
Thanks,
Simone
