            Bug ID: 12971
           Summary: qt5webengine: graph-depends seems producing incorrect
                    output
           Product: buildroot
           Version: 2020.02.2
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: seems.deviant at gmail.com
                CC: buildroot at uclibc.org

The graph-depends of the provided config

This is happening on current master: 3a9261ddd9 (HEAD -> master, origin/master,
origin/HEAD) package/libusb-compat: set LIBUSB_1_0_SONAME

Create a following .config:
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_MESA3D_OPENGL_ES=y
BR2_PACKAGE_QT5=y
BR2_PACKAGE_QT5WEBENGINE=y

Then call:
$ make graph-depends

And you'll see that qt5quickcontrols and qt5quickcontrols2 packages are not
marked as dependant on the qt5webengine package, although the qt5webengine has
selected both of them.

I would expect the dependency graph to be "ALL -> qt5webengine ->
{qt5quickcontrols,qt5quickcontrols2}" rather than "ALL ->
{qt5webengine,qt5quickcontrols,qt5quickcontrols2}"

qt5quickcontrols and qt5quickcontrols2 seems to be run-time dependencies as the
compile-time dependencies (see package/qt5/qt5webengine/qt5webengine.mk) are
only given as:

QT5WEBENGINE_DEPENDENCIES = ffmpeg libglib2 libvpx opus webp \
        qt5declarative qt5webchannel host-bison host-flex host-gperf \
        host-pkgconf host-python

And this ones are the ones shown in the graph-depends output...

--- Comment #3 from Thomas Petazzoni <thomas.petazzoni@bootlin.com> ---
Indeed as Peter said, graph-depends draws the graph of build-time dependencies,
as listed by the package <pkg>_DEPENDENCIES variable.

However, I find it odd that qt5declarative is only a runtime dependency for
qt5webengine, if it is needed, it should also be needed at build time, but
qt5webengine builds fine without this. Would it be possible to check if this
runtime dependency is really needed ?

qt5declarative (and with it qt5declarative-quick) is a compile time
dependency, only qt5quickcontrols and qt5quickcontrols2 are the runtime
dependencies (which is o.k. as the quickcontrols are normally only
referenced from qml/runtime and the c++ code/libs by plugin loading)...
