[Buildroot] [PATCH v2 00/24] Scientific libraries

[Samuel Martin]

Hi all,


Here is the 2nd round of the Scientific libraries series, which contains a
couple of new scientific packages, among these python Numpy, a bump of OpenCV
and some fixes/refactoring in OpenCV reverse dependencies.

Unlike the 1st post of this series, this new round is largely dominated by
OpenCV change sets, which have been heavily chainsawed to make easier the review
process. ;)


Yours,
Samuel

[Buildroot] [PATCH v2 01/24] qt: add an option to install the test module

[Samuel Martin]

When building Qt in a minimal configuration, a couple of Qt modules
(QtNetwork, QtSql, QtTest and QtXml) are built in addition to QtCore,
so they are installed in the sysroot but they are not copied into the
target tree.

Among these modules that could be built but optionally installed, only
QtTest had no option to allow being installed in the target fs.

Thus, programs linking against QtTest would successfully build, but
would miserably fail at runtime due to this missing dependency.

So far, the only package triggering this issue is OpenCV (the highgui
module built with Qt support).

A followup patch will add this missing dependency in OpenCV using this
new option.

[Buildroot] [PATCH v2 02/24] opencv: fix qt selection when highgui is enable

[Samuel Martin]

The OpenCV highgui module links against QtGui and QtTest.
The latter is built by default but was never installed.
Thanks to the previous patch on Qt, this can be rectified.

So, update the OpenCV Config.in with the missing Qt module selection.

[Buildroot] [PATCH v2 04/24] clapack: new package

[Samuel Martin]

This package provides BLAS and LAPACK libraries.

Though it is common to find implementation of these two libraries in
Fortran, this package provides a C-implementation for both, because:
- Fortran support has been deprecated in Buildroot since the 2013.11
  release;
- most of the external toolchains do not provide a Fortran compiler.

Often BLAS build-systems build some test programs and run them to
generate some source files or adjust some build optimizations, naively
assuming they are building the library for the build-machine. This does
not play well when cross-compiling.

This implementation has this defect too, by building and running a tool
generating a header.
However, the build-system allows to pass an empty header.
So, we have to patch the CMake to build the generator (but never
install it) and correctly support building with and without this header
provided by the user.

Also, few CMake patches are needed to fix the build and install rules.

[Buildroot] [PATCH v2 05/24] python-numpy: new package

[Samuel Martin]

This patch add NumPy package for python.

Since Fortran support has been deprecated in Buildroot since the 2013.11
release, and because most of the external toolchains do not provide a
Fortran compiler, it is necessary to explicity disable Fortran compiler
to avoid catching the one from the host system if any.

We also need to fill a site.cfg file to tell NumPy build-system where
it should looking for BLAS and LAPACK libraries.

Some packages may include headers provided by python-numpy package.
Thus, python-numpy needs to be installed in the sysroot; so add and
enable its install-staging command.

changes v1 -> v2:
- rebase
- automatic support of blas/lapack when clapack is enabled (ThomasP)
- split blas/lapack support in its own cset (ThomasP)
- merge python-numpy staging install cset within the python-numpy
  package integration (ThomasP)

[Buildroot] [PATCH v2 07/24] opencv: bump to version 2.4.8

[Samuel Martin]

This patch bumps OpenCV version and address the minimal set of change to
get the new version building correctly:
- update the download location;
- force Qt version to Qt 4 when support is enabled;
- naively fix the v4l support.

However, it does not address a couple improvements, among these:
- jasper support;
- python/numpy support;
- Qt4 and Qt5 support (since the 2.4.6 release), so only Qt4 support is
  supported in this patch;
- optional libv4l dependency (since 2.4.7 release);
- etc.
These will be addressed in followup patches.

[Buildroot] [PATCH v2 15/24] opencv: disable OpenMP support

Since there is currently no easy way to know if the current Buildroot
configuration has a toolchain supporting OpenMP (especially for external

[Buildroot] [PATCH v2 17/24] opencv: rework V4L/libv4l support

[Samuel Martin]

Starting with the 2.4.7 release, for V4L support, OpenCV does not
requires a libv4l dependency for its V4L support.

So, it now provides 2 distincts knobs for this: WITH_V4L and a new
one: WITH_LIBV4L.

This patch takes advantage of this new knob and libv4l support is
now automatically enabled if only the libv4l package is enabled.

In OpenCV, the logic behind this is:
- using libv4l if available,
- otherwise, use v4l2 or v4l API from the kernel if available.

[Buildroot] [PATCH v2 19/24] opencv: add Qt5 support

[Samuel Martin]

Starting with the 2.4.6 release, OpenCV supports both Qt4 and Qt5,
but only one can be enable at the same time.

Since Buildroot does not support Qt4/Qt5 co-existence, we keep the Qt
support knob as a boolean, but make it depend on BR2_PACKAGE_QT or
BR2_PACKAGE_QT5, and automatically uses the enabled one.

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 a
dependency. 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.

[Buildroot] [PATCH v2 20/24] opencv: add python/numpy support

[Samuel Martin]

opencv_python module needs python-numpy because it uses some numpy
headers in this wrapper.

A patch in the OpenCV's build-system is also needed to prevent it from
trying to run python for numpy detection. This patch has already been
integrated upstream.

[Buildroot] [PATCH v2 21/24] opencv: define modules inter-dependencies

[Samuel Martin]

OpenCV allows to enable/disable the selection of modules (a.k.a.
opencv libraries). These modules depend one from 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 module
dependencies.

This patch replicates the modules' dependency relations in the
Config.in, so that the selection of the user will actually be built.

There's now 4.300 availble. If 4.000 is a requirement, there's now
4.000.5.

With the patch re-ordering, plus the alphabetical sort, you can add my
reviewed tag (not added here, so patchwork does not catch it.)

[Buildroot] [PATCH v2 04/24] clapack: new package

[Yann E. MORIN]

Samuel, All,

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:
> This package provides BLAS and LAPACK libraries.
> 
> Though it is common to find implementation of these two libraries in
> Fortran, this package provides a C-implementation for both, because:
> - Fortran support has been deprecated in Buildroot since the 2013.11
>   release;
> - most of the external toolchains do not provide a Fortran compiler.
> 
> Often BLAS build-systems build some test programs and run them to
> generate some source files or adjust some build optimizations, naively
> assuming they are building the library for the build-machine. This does
> not play well when cross-compiling.
> 
> This implementation has this defect too, by building and running a tool
> generating a header.
> However, the build-system allows to pass an empty header.
> So, we have to patch the CMake to build the generator (but never
> install it) and correctly support building with and without this header
> provided by the user.
> 
> Also, few CMake patches are needed to fix the build and install rules.

In case something else requires you to resend this patch:
    s/few/some/  ;-)

The way you wrote it implies that it is unusual there are so few
required patches, and that ususally more are needed. Hehe! ;-)

[Buildroot] [PATCH v2 05/24] python-numpy: new package

[Yann E. MORIN]

Samuel, All,

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:

> We also need to fill a site.cfg file to tell NumPy build-system where

> 
> Some packages may include headers provided by python-numpy package.
> Thus, python-numpy needs to be installed in the sysroot; so add and
> enable its install-staging command.

So, maybe we should:
    depends on uClibc && x86 || glibc

uClibc only really supports fenv.h for x86.

Why not add it to the python-infra, then?

Yep, i think bumping packages is often easier than getting them
integrated, so i keep it for later (the same is true for opencv,
numpy, and maybe others ;-])

Uh? Did you forget to dereference the BR2_PACKAGE_CLAPACK variable? ;-)
Anyway, see also below...

> +PYTHON_NUMPY_SITE_CFG_LIBS = \
> +	$(if $(BR2_PACKAGE_CLAPACK),blas lapack)

We prefer using multi-line syntax. See:
    http://buildroot.net/downloads/manual/manual.html#writing-rules-mk

So:

    ifeq ($(BR2_PACKAGE_CLAPACK),y)
    PYTHON_NUMPY_DEPENDENCIES += clapack
    PYTHON_NUMPY_SITE_CFG_LIBS += blas lapack
    endif

That last one is a new one; the patch is thus not strictly about re-ordering.

Is it a left-over from a previous iteration? Can it rather be done in a
separate patch?

[Buildroot] [PATCH v2 10/24] opencv: sort and reorder HW support options

[Yann E. MORIN]

Samuel, All,

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:
> Sort per HW features and disable their support when it is not suppported

Strictly speaking, you are also adding some more config options. But it
seems they are needed to properly work. Say so in the commit log.

An alternate solution would have been to really do only the re-ordering
in those patches, and add a single new patch to add the missing bits?

> Signed-off-by: Samuel Martin <s.martin49@gmail.com>

Add a bit more to the commit log, then:

Here you have two options to disable it:
    -DBUILD_opencv_ocl=OFF
    -DWITH_OPENCL=OFF

But I did not see the same schema with other modules, such as the
dynamic cuda, where you only have:
    -DBUILD_opencv_dynamicuda=OFF

and not:
    -DWITH_DYNAMIC_CUDA=OFF

You are the cmake guy, but I'd like to understand the discrepancy
between the two, which when I look at the code, are defined in a similar
way.

Yann E. MORIN.

A testbuild shows it needs largefile (STAT_ST isn't defined for !LFS),
so I've added that.

s/not/are not/.

I've done similar small changes to some of the other patch

[Buildroot] [PATCH v2 15/24] opencv: disable OpenMP support

Samuel, All,

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:
> Since there is currently no easy way to know if the current Buildroot

Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

A solution to that would be to add a config knob to enable/disable
building openmp for the internal toolchain, and to state whether the
external toolchain has/lacks openmp.

[Buildroot] [PATCH v2 17/24] opencv: rework V4L/libv4l support

[Yann E. MORIN]

Samuel, All,

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:
> Starting with the 2.4.7 release, for V4L support, OpenCV does not

I don't think we want to have such comments. As I said in my previous
review, it is enough (INHO) to just state so in the help entry.

Except under rare circumstances, we do not warn the user that way. The
usual way is to enable support if the needed package is selected, and
to disable the support otherwise.

Regards,
Yann E. MORIN.

This is still a bit unclear. What about:

    help
      Enable jpeg2000 support.

      Note: this does not use the libjasper bundled with opencv, but
      uses the libjasper package installed system-wide by Buildroot.

[Buildroot] [PATCH v2 19/24] opencv: add Qt5 support

[Yann E. MORIN]

On 2014-04-23 01:15 +0200, Samuel Martin spake thusly:

Same comment as my previous review: why do you repeat the Qt4/Qt5
dependencies since you already depend on Qt4/Qt5 ?

Eeew...

What about:

    config BR2_PACKAGE_OPENCV_WITH_QT
        bool "Qt backend"
        depends on BR2_PACKAGE_QT || BR2_PACKAGE_QT5
        select BR2_PACKAGE_OPENCV_QT4_BACKEND if BR2_PACKAGE_QT
        select BR2_PACKAGE_OPENCV_QT5_BACKEND if BR2_PACKAGE_QT5
        help
          Enable Qt support for OpenCV.

          This uses whatever Qt version you enabled: Qt4 or Qt5.

    config BR2_PACKAGE_OPENCV_QT4_BACKEND
        bool
        select BR2_PACKAGE_QT_STL
        select BR2_PACKAGE_QT_GUI_MODULE if BR2_PACKAGE_OPENCV_LIB_HIGHGUI
        select BR2_PACKAGE_QT_TEST       if BR2_PACKAGE_OPENCV_LIB_HIGHGUI

    config BR2_PACKAGE_OPENCV_QT5_BACKEND
        bool
        select BR2_PACKAGE_QT5BASE
        select BR2_PACKAGE_QT5BASE_CONCURRENT
        select BR2_PACKAGE_QT5BASE_TEST
        select BR2_PACKAGE_QT5BASE_GUI
        select BR2_PACKAGE_QT5BASE_WIDGETS

    comment "Qt backend needs either Qt4 or Qt5"
        depends on !BR2_PACKAGE_QT && !BR2_PACKAGE_QT5

Then, as soon as one or the other is selected, the comment disapears,
and the option becomes visible.

We prefer using multi-line. But I agree, this single-line is clear and
concise, so I don;t much care.

I'll trust you on this dependency chain. ;-)

As clapack needs largefile, then so does armadillo.

Committed with this and Yann's ordering comment fixed, thanks.

Thanks, applied, after changing the patch to use the python package
infrastructure for staging installation, and adding the necessary
dependencies to take into account the fenv.h requirement.

[Buildroot] [PATCH v2 06/24] python-numpy: add optional blas/lapack support

I've changed this as suggested by Yann E. Morin.

In the example site.cfg file, the syntax is

	libraries = library1,library2

so I've changed this logic to use this syntax, and I've applied your
patch.

Can you check that things are working properly by testing the latest
master? I've checked that things build properly, but I'm not sure how
to test that python-numpy and the blas/lapack support work properly.

Thanks!

This one had comments from Yann that have never been addressed. Please
resend an updated version that takes into account these comments. In
the mean time, I've marked this patch as "Changes Requested" in
patchwork.

All those patches have pending comments from the review made by Yann a
long time ago, and those comments were never addressed. Could you
please address those comments, and send a new version of the patch
series on top of master? In the mean time, I've marked those patches as
"Changes Requested" in patchwork.

Also, please look for the autobuilder results in the next days to fix
any numpy or opencv related failure.

Thanks,

Thomas
