[Xenomai-core] Debian lintian warning: symlink-is-self-recursive

[Roland Stigge]

Hi,

Debian's lintian(1), the package checker, tells me:

=========================================================================
W: libxenomai-dev: symlink-is-self-recursive
usr/include/xenomai/asm-generic/xenomai .
N:
N:   The symbolic link is recursive to a higher directory of the symlink
N:   itself. This means, that you can infinitely chdir with this symlink.
N:   This is usually not okay, but sometimes wanted behaviour.
N:
W: libxenomai-dev: symlink-is-self-recursive
usr/include/xenomai/asm-sim/asm .
W: libxenomai-dev: symlink-is-self-recursive
usr/include/xenomai/asm-sim/xenomai .
W: libxenomai-dev: symlink-is-self-recursive
usr/include/xenomai/asm-x86/xenomai .
W: libxenomai-dev: symlink-is-self-recursive usr/include/xenomai/xenomai .
=========================================================================

I.e. installing Xenomai created those recursive links which might be
there for source compatibility reasons. Can they be removed at some
point or should I accept the above issue as intended for the future?

Thanks,

Roland

No comment from anyone? Maybe I should detect the necessity for those
links by removing and seeing if anyone complains? ;-)

bye,

Those links are intended. We need them to build applications, so that the
include paths in userland look like the kernel ones, since we share header files
between both environments.

If we really wanted to remove the recursive symlinks (I do not advocate
this, in fact I have no opinion about it, for instance are there really
tools that go wild with such links ?), we could move include/asm-* to
include/xenomai/asm-* and use #include <xenomai/asm/foo.h> everywhere.
