[Buildroot] [PATCH 0/4] Fix a few unmet dependencies (branch yem/unmet-deps)

[Yann E. MORIN]

Hello All!

This series fixes a few unmet direct dependencies, like so:

warning: (BR2_INIT_SYSTEMD) selects BR2_TARGET_GENERIC_REMOUNT_ROOTFS_RW
which has unmet direct dependencies (BR2_ROOTFS_SKELETON_DEFAULT)

However, there is one such unmet direct dependency I was not able to
understand (with this series already applied):

$ make KCONFIG_SEED=0x9F309288 randconfig
warning: (BR2_PACKAGE_OPENCV_WITH_GSTREAMER && BR2_PACKAGE_OPENCV3_WITH_GSTREAMER)
selects BR2_PACKAGE_GST_PLUGINS_BASE which has unmet direct dependencies
(BR2_PACKAGE_GSTREAMER)
warning: (BR2_PACKAGE_FREERDP_GSTREAMER && BR2_PACKAGE_QT_WEBKIT &&
BR2_PACKAGE_OPENCV_WITH_GSTREAMER && BR2_PACKAGE_OPENCV3_WITH_GSTREAMER) selects
BR2_PACKAGE_GST_PLUGINS_BASE_PLUGIN_APP which has unmet direct dependencies
(BR2_PACKAGE_GSTREAMER && BR2_PACKAGE_GST_PLUGINS_BASE)

As far as I can see, the dependencies of gstreamer and gst-plugins-base
*are* properly propagated to the offending packages. I think I'm gonna
loose my sanity on that one... :-/ If any one feels adventurous...

Regards,
Yann E. MORIN.

Properly propagate the Xenomai dependencies to the kernelexternsion, to
fix the following unmet dependencies:

warning: (BR2_LINUX_KERNEL_EXT_XENOMAI) selects BR2_PACKAGE_XENOMAI
which has unmet direct dependencies (BR2_PACKAGE_XENOMAI_ARCH_SUPPORTS
&& BR2_TOOLCHAIN_HAS_THREADS && !BR2_TOOLCHAIN_USES_MUSL)

While at it, move the comment lower, after the path option, so that the
path option is properly indented in the menuconfig.

Add markers to separate each extension.

Do you have some sample .config that exhibits those problems? I had a
quick look, and it indeed seems weird. opencv is select both gstreamer
and gst-plugins-base, so I don't see why the dependency of
gst-plugins-base on gstreamer is a problem.

As explained above, just run:

make KCONFIG_SEED=0x9F309288 randconfig

But it may no longer work, since the set of options has changed now. You
can reproduce it with:

$ git checkout f4918b3a
$ make KCONFIG_SEED=0x9F309288 randconfig

(f4918b3a is master before you applied the last few patches changing the
set of options).

Neither do I.

And if you run "make olddefconfig" there is no error anymore... :-/

I guess it must be a weird side-effect of the randconfig. The
BR2_PACKAGE_OPENCV_WITH_GSTREAMER && BR2_PACKAGE_OPENCV3_WITH_GSTREAMER
bit is very wrong (opencv3 depends on !opencv).
