This major version bump is in fact a bump from 2.4.10 to 2.4.11, then to
3.0.
OpenCV-2.4.11 improves a lot the Buildroot integration, including a
couple of patches that are no longer needed:
- x86 PIC code compilation fix in core module [1];
- return type fix in superes module [2];
- opencv.pc generation [3].
It also improves the gstreamer-0.10/1.x detection [4], that will be
needed in a follow-up patch.
OpenCV-3.0 still requires 2 patches (backported from upstream fixing
pthread support [5,6].
The OpenCV-3.0 does some major changes, for which a transition guide
has been published [7].
Among these changes coming with OpenCV-3.0, some new modules have been
introduced and others got removed; leading to a bunch of configure
option updates (to keep as much as possible an iso-functional-perimeter)
and the legacy menu has been updated too.
The worth noticing removals being:
- the opencv_legacy and opencv_nonfree modules no longer exist;
- the opencv_contrib module has moved out of the opencv base tree and
now has its own repository [8].
There is currently no plan to support it.
Some 3rd-party supports have been improved or added; their integrations
in Buildroot will be addressed in follow-up patches.

-Subject: [PATCH] cmake/OpenCVGenPkgconfig.cmake: rework opencv.pc generation
-
-Using absolute path to locate the components in the "Libs:" field of the
-*.pc can badly break cross-compilation, especially when building
-statically linked objects.
-
-Indeed, pkg-config automatically replaces the '-I...' and '-L...' paths
-when the PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_LIBDIR environment
-variables are set [1]. This feature is very helpful and common in
-cross-compilation framework like Buildroot [2,3].
-
-When there are absolute paths in the *.pc files, pkg-config won't be
-able to do the path substitions for these paths when the afromentioned
-environment variables are set.
-In such case, since the prefix is the target one, not the sysroot one,
-these libraries' abolute paths will point to:
-- in the best case: a non-existing file (i.e. these files do not exists
- on the host system;
-- at worst: the host system's libraries. This will make the linking
- failed because these host system's libraries will most likely not be
- build for the target architecture [4].
-
-So, this patch replace the components' absolute paths by the form:
- -L<libdir> -l<libname>
-
-This way, the linker will be able to resolve each dependency path,
-whatever the kind of objects/build (shared object or static build) it
-is dealing with.
-
-Note that for static link, the library order does matter [5]. The order
-of the opencv components has been carefully chosen to comply with this
-requirement.
-
-Fixes #3931

"automatically enabled" suggests that we do have (Kconfig) options to
enable them, which is not the case. What about:
Note that the opencv_core module and the opencv_hal library are
always built and installed, not matter which other modules are
enabled below.

I forgot to say so in my previous review, but we ususally do not add
such explications in the prompt, but in the help text. Besides, since
you do not update the existing prompts accordingly, it makes the whole
menu inconsistent, because some prompts have explanations, some don't.
(Note that this comment is valid for all entries; I won't repeat it.)

Furthermore, the proposed help text is not very helpful. A help text,
when present, should have some explanations that go further than just
repeating the promopt with syntaxic sugar. What about (adapt list, of
course):
config BR2_PACKAGE_OPENCV_LIB_IMGCODECS
bool "imgcodecs"
help
Include opencv_imgcodecs module, to provide image codecs,
like jpeg, png, gif...
(Ditto, comment valid for all following entries.)
But others may disagree, of course. ;-)

OK, there is a patch later on that deals with prompt and help texts.
Let's see that...
However, I find it dubious that you add those texts in this patch, to
later remove them in a following patch. Why not just omit them to begin
with?
Regards,
Yann E. MORIN.

The opencv plugin uses stuff from the now removed opencv's legacy module.
Note that the configure script already correctly check the opencv version
and disable the opencv plugin with opencv-3.x.
Also remove 'select ...' to prevent kconfig from complaining about
recursive dependencies.

OpenCV allows to enable/disable the selection of modules (a.k.a.
opencv libraries). These modules depend one on the others; these
dependencies are already handled by the build-system (CMake).
However, the way we handled them in Buildroot was not really clean.
For each opencv module, there is a kconfig option, but we forced the
corresponding CMake config option without checking for the modules'
dependencies.
This patch replicates the modules' dependency relations in the
Config.in, so that the selection of the user will actually be built.

To: buildroot
Since its integration into Buildroot, OpenCV always enables all modules
by default because the inter-module denpedency were not supported.
Now that OpenCV inter-module dependencies are correctly set at the
Buildroot configuration level, it is possible to reduce the enabled
module list to its minimal set, letting kconfig enable the other
modules.
This change will not change anything WRT a defconfig build with opencv.

Although I'm usually not opposed to getting the smallest possible config
as a default, as you say this one breaks existing defconfigs.
OTOH, do we really care?
Anyway, I won't ack this one, but I am not ooposed to it being merged
either.

Yann E. MORIN.

This should have been a comment to the following patch:
package/opencv: disable all modules by default
Sorry for the confusion...

This change allows to reduce the size of the default OpenCV package, so
the final root filesystem.
However, this will break any existing defconfig enabling OpenCV. Indeed,
a minimal OpenCV package will be built, whereas, prior to applying this
patches, a full-featured one would have been built instead.

Although I'm usually not opposed to getting the smallest possible config
as a default, however as you say this one breaks existing defconfigs.
OTOH, do we really care?
Anyway, I won't ack this one, but I am not opposed to it being merged
either.

I think we break defconfigs (as in, the result of 'make savedefconfig') fairly
often without really noticing. An obvious example is the kernel headers version.
But also for example with the ARM ABI rework (I'm not 100% sure but I think
there are defconfigs that would have changed).
So I think breaking defconfigs is OK. To update to a new buildroot version you
should start from a full .config, not a defconfig.

Arnout

opencv_python module needs python-numpy because it uses some numpy
headers in this wrapper.
From its 2.4 release, OpenCV offers python bindings, but they required
most of the OpenCV modules to be enabled.
Since OpenCV-3.0.0, python bindings have been reworked:
- it now supports both python2 and python3
- only built modules supporting wrapped in python will be included in
the bindings.

With Python2 enabled, I still see this in the configure log:
-- Python 2:
-- Interpreter: /home/ymorin/dev/buildroot/O/host/usr/bin/python2 (ver 2.7.10)
-- Libraries: /home/ymorin/dev/buildroot/O/host/usr/i586-buildroot-linux-gnu/sysroot/usr/lib32/libpython2.7.so (ver 2.7.10)
-- numpy: /home/ymorin/dev/buildroot/O/host/usr/i586-buildroot-linux-gnu/sysroot/usr/lib/python2.7/site-packages/numpy/core/include
(ver undefined - cannot be probed because of the cross-compilation)
-- packages path: /usr/lib/python2.7/site-packages
--
-- Python 3:
-- Interpreter: /usr/bin/python3.4 (ver 3.4)
--
Should we force the configure step to find python3 as something like
/bin/false to avoid any potential issue, even if we already pass
-DBUILD_opencv_python3=OFF
(Similarly with python2 when python3 is enabled, of course.)

Thios comment is now gone, and there's no longer any hint that python
support can be enabled by selecting python2 or python3. But see below...

It would probably be good to introduce a numpy kconfig variable that
syummraises al those dependencies, like so:
config BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS
bool
default y
depends on BR2_aarch64 || BR2_arm || BR2_armeb || blabla
depends on !BR2_TOOLCHAIN_USES_UCLIBC || BR2_i386 || BR2_x86_64
and use that here instead of repeating the whole stuff (which is
difficult to maintain, should python-numpy's dependencies change in a
future version).
And then you could easily add a comment:
comment "python support needs either python2 or python3"
depends on BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS
depends on !BR2_PACKAGE_PYTHON && !BR2_PACKAGE_PYTHON3
Which means I withdraw my reviewed-by tag, sorry. :-(

Yann E. MORIN.

OpenCV 3.0 support both gstreamer-0.10 and gstreamer-1.x, but only one
is used at the time.
This patch turns the gstreamer support into a choice, in order to prepare
adding the support for gstreamer-1 in a following patch.

Although I don't like it much, we usually have the comment in the choice
itself, see for example the external toolchain choice.
> +choice
> + prompt "gstreamer support"

So, this means the choice will not be visible when gstreamer is missing
its dependencies.
Instead, I'd do something like is done (in a later patch) for the GUI
toolkits, that is always show the choice, but hide whatever entries are
not available:
choice
bool "gstreamer support"
config BR2_PKG_OCV_GST_NONE
bool "none"
config BR2_PKG_OCV_GST_0_10
bool "gstreamer 0.10"
depends on BR2_USE_MMU # gst-0.10
depends on BR2_USE_WCHAR # gst-0.10
depends on BR2_TOOLCHAIN_HAS_THREADS # gst-0.10
comment "gst-0.10 support needs a toolchain w/ wxhar, threads"
depends on BR2_USE_MMU
depends on !BR2_USE_WCHAR || !BR2_TOOLCHAIN_HAS_THREADS
endchoice

Yann E. MORIN.

Starting with the 2.4.10 release, OpenCV supports both Gstreamer-0.10
and Gstreamer-1, but only one can be enabled at the same time (OpenCV
chooses Gstreamer-1 over Gstreamer-0.10 when both are available).

And then, of course, update the comment from the previous patch, to
encompass both gstreamer versions.

Note that this situation is not ideal because it only add openmp support
to the Buildroot toolchain, not the external ones; but a couple of
packages already are in this situation.

This patch moves the existing Qt4 and gtk2 options in that choice
because, in OpenCV, only one toolkik will be actually used at the time,
given priority to Qt4.

Incomplete commit log (minor!):
Also add comments when the toolkit are not available because
of missing dependencies.

If that depends on highgui, then maybe it would be better to put the
choice right below the option for highgui, no?

Do we really need this "preference" comment in the help text?
If thue user selects gtk2 as a toolkit for OpenCV, but also has Qt4
enabled, surely we'd build an OpenCV with gtk2 support and no Qt4
support, right?
So, there's no reason to have this comment, I think. Or it should maybe
rewritten, sometyhing like:
The best toolkit to work with OpenCV are, in decreasing order of
preference by the OpenCV build system):
- Qt4
- gtk2
Note that, whatever you choose here will be used by OpenCV, even
if you also enabled a more preferred toolkit in your Buildroot
configuration.
(Not that this is perfect either, but still...)
Otherwise:

Starting with the 2.4.6 release, OpenCV supports both Qt4 and Qt5 as GUI
toolkit, but only one can be enabled at the same time.
Since Buildroot does not support Qt4/Qt5 co-existence, we make the Qt4
knob depend on BR2_PACKAGE_QT5.
Note that we usually use 'select ...' to express the dependencies
between packages, but in this case, we cannot since the Qt4/Qt5
co-existence exclusion is not handled by a simple choice, but by some
extra dependencies in the choice entries. This makes impossible using
'select ...' for the Qt support knob without triggering a circular
dependency at the kconfig level.
Besides, we already use 'depends on ...' to express the dependencies
with some "big" packages (like xorg or libgtk2). qt or qt5* packages
are fairly big. So, I don't think it will hurt that much to use a
'depends on ...' statement in this case.

No need to add those dependencies, they are inherited with the Qt5
dependency. Besides, Qt5 does not depend on MMU.

BR2_PACKAGE_QT5BASE_TEST is a noop now, see package/qt5/qt5base/Config.in:

Since Qt5 can be built for noMMU, I think these dependencies are wrong.
Probably we want just:
comment "qt5 support needs qt5"
depends on !BR2_PACKAGE_QT && !BR2_PACKAGE_QT5
Here's a defconfig matching all the requirements for noMMU and
Qt5 available (totally untested! ;-) just to validate the comment
dependencies):
BR2_bfin=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_WCHAR=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y

Fully rework the GTK support in OpenCV because it now supports gtk-2 and
gtk-3 (but only one at the time).
Note that, in the build-system, the gtk support is only available when
Qt support is disabled; so make sure the menuconfig reflects this.

Those last two lines no longer make sense now that we're using a choice.

My reviewd-by tag was before there was this big choice (which I did
suggest you do). It no longer stands now, sorry.

Why do you re-order the dependencies here? There's no real reason for
that.
(Except you might want to align the ordering to the one for gtk3? I
don't think it's needed...)

And here you have this extraneous endif that is now useful. ;-)

So, have you tried a build with both gtk2 and gtk3 enabled, but with
OpenCV using gtk2?

In OpenCV, OpenGL support is done using extensions from 3rd party
framework: either Qt5OpenGL with Qt5 (with GL support only, not GLES);
or gtkglext (which is not available in Buildroot) with gtk2
So, make OpenGL knob visible when Qt5 support is selected.

"But I do have Qt5 enabled and a GL provider set" would say a dumb user
like me with Qt5 enabled and mesa3d (with DRI driver), but with the
opencv toolkit set to gtk2.
What you meant was: "opengl needs Qt5 as toolkit and an openGL proivder"
But that's not much better either.
What would really make it obvious is:
comment "opengl support needs an OpenGL provider"
depends on BR2_PACKAGE_OPENCV_WITH_QT5
depends on !BR2_PACKAGE_QT5_GL_AVAILABLE \
|| !BR2_PACKAGE_HAS_LIBGL
No, I did not forget to negate BR2_PACKAGE_OPENCV_WITH_QT5, because what
I suggest is that opengl support be treated as a sub-option of Qt5, so
be the comment.
Regards,
Yann E. MORIN.

This change adds 2 patches (backported from upstream) to vlc fixing the
build against opencv2 APIs.
This allows to select the minimal set of opencv modules when opencv
support is enabled.

Applied.

Applied.
For the other patches, I'm waiting for some more review (and some of
the patches have comments from Yann).
Thanks a lot for working on OpenCV!
