[Buildroot] [PATCH v6 13/13] package/qt6: Add qmake functionality

[Angelo Compagnucci]

From: Jesse Van Gavere <jesseevg@gmail.com>

The qmake functionality had been missing due to the new host/target
build requirement, to get it working the main parts of the qt5 qmake
has been kept, we're still making our own device spec which we use to
run qmake with along with passing some additional device options for our
flags/cross-compiler the biggest difference is that where previously
qt.conf was used to fixup per-paths builds, this is now always
created with changed contents so qmake looks at the correct target
directories.

This line was not correct: (1) this package is not needed and (2) it
was not selected in Config.in, causing a build failure because we don't
allow depending on a package that isn't selected in Config.in.

I fixed that up when applying. Thanks!

It doesn't enable fontconfig and freetype, but only fontconfig.
Freetype is unconditionally enabled for the GUI module.

I fixed that up when applying. Thanks!

Missing else clause to explicitly disable widgets.

Applied with these two things fixed. Thanks!

This option didn't do anything: there is nothing in the .mk file that
did something about this option, so I dropped it.

I dropped the "default y", there is no need for that.

It also needs EGL.

I also moved this option closer to the other graphics backends
(linuxfb, xcb).

libgbm added here, since according to Config.in we need it.

Applied with those fixes, thanks!

Why is that a def_bool y? I see it's like that in qt5base, but I'm not
sure why. I changed it to be a normal option:

config BR2_PACKAGE_QT6BASE_PRINTSUPPORT
        bool "printing support"
        # yes, print support needs widgets
        depends on BR2_PACKAGE_QT6BASE_WIDGETS
        help
          This option enables printing support, optionally using CUPS
          if available.

Spurious space before y

Same.

Applied with those fixes. Thanks!

Due to comments/issues on previous patches, this option does not exist,
so I'm not able to apply this patch right now.

Could you resend as part of a new series after checking this
BR2_PACKAGE_QT6BASE_OPENGL_LIB thing?

Also, are all those options needed to have the examples? I believe with
Qt5, when you enable the examples, it builds only the examples that it
can build based on the features enabled in Qt. This was very handy. The
same is not possible here?

Best regards,

Thomas

This looks very very odd, and most likely doesn't work. If I understand
correctly, this is a path that will be interpreted relatively to
$(HOST_DIR), so this value assumes that host/ and target/ are side by
side, but that's not true in the general case. Indeed, BR2_HOST_DIR
allows to customize where $(HOST_DIR) is located, and it can be
elsewhere than side by side to target/.

What is this trying to do exactly?

Where is QT6_INSTALL_QT_CONF implemented ?

Re: [Buildroot] [PATCH v6 13/13] package/qt6: Add qmake functionality

[Jesse Van Gavere]

Hello Thomas,

You're right, this won't work with a relocated HOST_DIR the
QT6_INSTALL_QT_CONF seems to have gotten dropped in Angelo his patch
series, I'll rebase onto what has been approved and submit a new
series for the qmake functionality.
Thanks for the reviews!

Regards,
Jesse
