Maybe we could add EXTRA_CFLAGS=-I$(TOPDIR)/include/xenomai to every
xenomai kernel makefile
Yes, I would preferably merge that instead of playing with symlinks.
and to the cflags returned by xeno-config for
kernel-space applications ?
There no such support in xeno-config anymore. Kernel module flags and
dependencies now exclusively belong to the kernel build system;
xeno-config is only relevant for building user-space apps.
Actually, my concerns only targeted the userspace applications, more
precisely those few being built inside the xeno tree. External user apps
can still use the standard, non-prefixed headers. Thus my idea was to
unify the includes for those in-tree applications so that users who are
taking them as reference only see the standard way.
Ack, but this is a matter of general consistency. Now that the issue is
raised and that we need to address it, it's better if we don't have to
fiddle with exception cases uselessly, so using the proper include
directives for both internal/external cases is the best way to go;
provided it works, but it should.
External kernel applications and drivers can and should catch this
prefix by adding <linuxsrc>/include/xenomai to their makefiles.
