(In reply to Patrick Koller from comment #0)

Hello Patrick,

no actual experience with the imx-gpu-viv package and qt/wayland, but
a quick test with your provided polytab_defconfig showed the same error.

Second test was without qt, only wayland/weston, did not compile out of the box, a quick fix was to upgrade to a buildroot toolchain instead of the given gcc-linaro-4.9.4 toolchain (did not investigate further).

You can try to fix the eglfs_viv_wl errors (by adding the needed pointer casts) or disabling qt eglfs support (with wayland/weston your want to run your
application with '-platform wayland' instead '-platform eglfs'), or try to
run wayland/weston only first (without Qt)...

And last but not least you can try to run the open source etnaviv support (see e.g. imx6-sabresd_qt5_defconfig, your need to enable etnaviv support in librm, mesa3d and linux mainline kernel)...

Regards,
Peter

Patch to reproduce the problem

This patch provides the configuration to build my project with weston-imx successfully without Qt5. As soon as Qt5 is selected, the build fails as follows:

*** Reproduce the Qt5 build error ***
- Apply the attached patch to buildroot-2018.11
- make polytab_defconfig
- make
- Get the error:
qeglfsvivintegration.cpp:68:60: error: invalid conversion from ‘void*’ to ‘EGLNativeDisplayType {aka wl_display*}’ [-fpermissive]

*** Reproduce a successful build ***
- Apply the attached patch to buildroot-2018.11
- make polytab_defconfig
- make xconfig
- uncheck Qt5
- make

Weston/Wayland without Qt is working fine. The vivante examples are working excellent, too.

@Peter:
Thanks for your suggestions. I can not disable qt eglfs support completly, since I need the qt5webengine in my application, which requires eglfs support. So, my next step is to add the needed pointer casts and hope for success. I will report my progress here.

The previously mentioned error could be solved by casting the pointers manually. Thanks to @Peter.

And try to enable/build qt5webengine (and keep qt eglfs support disabled),
builds fine here, not run time tested...

The imx-gpu-viv/qt eglfs compile problem (if there is no easy/quick fix) is better addressed at a qt mailing list/qt bugtracker (if you do so, please
link it from here)...

Thanks @Peter for your patch.

The qt5webengine has been built just fine, nevertheless there was raised an error during the following "installing to target" step. The cp command complained, there are no libs to copy and indeed, there are no libs present. Why is the buildprocess successfull without creating any libs? Please have a look at the following error message:

Strange, the copy source paths should be

/home/patrickk/tmp/buildroot/eglfs_patch/output/staging/usr/lib/libQt5WebEngine*.so.*

...but should not matter, because staging is a symlink to host/arm-buildroot-linux-gnueabihf/sysroot...


Can you find the libs somewhere else (e.g. the build directory)?

Do you use ccache and hit by [1] (you need a buildroot git update or [2])?

Try a complete re-build (make clean; make)?

Any errors in the qt5webengine unpack/configure steps?

Regards,
Peter

Hi Peter

Thanks for your reply. No, I did not use the ccache nor were there any errors in the qt5webengine unpack/configure steps.

Nevertheless, after a "make clean" (Which I also made before my last post) shows now the "qt5wayland" first:

**************************************************

Does anybody have an idea, why this happens?
Thanks in advance.

(In reply to Patrick Koller from comment #6)

Still the same advice:

Did run my successful build with buildroot gcc-7.4.0 toolchain...

Hi Peter,

Thanks for your hint. Now, I am able to build wayland/weston (without qt) sucessfully (With both toolchains). As soon as I try to build qt5, the previous mentioned error (qwaylanddisplay.cpp:315:35: error: could not convert ‘{listener, data}’ from ‘<brace-enclosed initializer list>’ to ‘QtWaylandClient::QWaylandDisplay::Listener’) occurs. Do you have a hint to solve this problem?
Thanks in advance.


Best regards

Patrick

Please do not mix toolchains, I doubt wayland/weston builds with the linaro
toolchain (see comment #1), please re-build complete (make clean; make) (the complete buildroot build, not only a single package)  after changing to the buildroot toolchain (used buildroot git latest, gcc-7.4.0, qt-5.11.3)...

In case of failure post your .config/defconfig

(In reply to Peter Seiderer from comment #11)

From your build failure log:

make[3]: Entering directory '/home/patrickk/tmp/buildroot/a/output/build/qt5wayland-5.11.2/src/compositor'

...disable the BR2_PACKAGE_QT5WAYLAND_COMPOSITOR option and try again (this time
after make qt5wayland-dirclean), no need for the qt5wayland compositor, you have
already weston enabled)...

Regards,
Peter
