[meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

[-- Attachment #1.1: Type: text/plain, Size: 975 bytes --]

Hi,

It seems that there are some stiff missing between meta-qt5 or meta-raspberrypi.
When we set the option gles... to qtbase we don't get the QMAKE_LIBS_EGL set properly.
We can compare a working set of variables in the qt mkspecs directory of qt.
There is one dedicated file for the RaspberryPi2. May be one also for RaspberryPi.
Anyway!
How could we set those *_EGL variables properly? And... If they are properly set, will qtbase will take them into account?

I will be happy to propose a patch but I need to get more precision first.
Thanks in advance,

[meta-raspberrypi][PATCH v3 1/2] qt5: fixed raspberrypi support

[John Madieu]

    Because EGL properties were not defined properly, we always had the following error
        make: *** [egl] Error 1
        | EGL disabled.
        |  The EGL functionality test failed; EGL is required by some QPA plugins to manage cont
        |  You might need to modify the include and library search paths by editing QMAKE_INCDIR

    x11 in DISTRO_FEATURES also produced the following error
        error: 'QAccessible' has not been declared
        |              } else if (QStyleHelper::isInstanceOf(groupBox->styleObject,

Firstly show the DISTRO_FEATURES may be you are missing some important knobs for EGL
like openGL and gles2 etc.

Re: [meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

[-- Attachment #1: Type: text/plain, Size: 2611 bytes --]

Hi everyone,

I understand that you are all rewriting the qtbase rule to include at least the modification to the QMAKE_LIBS_EGL variable.
The question is:
Could we make somehow some work in meta-qt5 or meta-raspberrypi to not have to overwrite the qtbase rule.
For instance… meta-raspberrypi is providing a package config file for EGL. May be you could have meta-qt5 read this package config.

That’s the question. I’d like to know what the maintainers of those two layers think about that.

Best Regards,

I dont understand. PAKCAGECONFIGS are specifically desined for this
kind of scenario

Re: [meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

Setting properly the variable PACKAGECONFIG_GL to gles2 does NOT update properly the variable QMAKE_LIBS_EGL.
By default QMAKE_LIBS_EGL = -lEGL
And depending on hardware... it might be something like QMAKE_LIBS_EGL = -lEGL -lGLESv2 for instance.
And this specific line... "-lEGL -lGLESv2" is only know in the provider of virtual/libglesv2 ... in this case meta-raspberry.
The BSP layer could provide a package config file which will be read to set QMAKE_LIBS_EGL properly.

=> Which means we would need each package providing virtual/libglesv2 ... to provide also a package config file.

I hope it's clear now. Tell me if I missed something.

packageconfig could be used if libnames are consistent. something
qtbase can be looked into.

for oe you can pass qmake variables like
QMAKE_LIBS_EGL = -lEGL -lGLESv2

using EXTRA_QMAKEVARS_PRE variable.

Re: [meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

I'm saying that meta-qt5 should directly GRAB the proper EGLFS settings from the virtual/libgles2 provider.
If qt and gles2 then grab necessary information. If information not present then use defaults like -lEGL in this case.

I guess it should be possible to get the information from a package config.

The BSP layer should not care about Qt.

packageconfig could be used if libnames are consistent. something qtbase can be looked into.

for oe you can pass qmake variables like QMAKE_LIBS_EGL = -lEGL -lGLESv2

using EXTRA_QMAKEVARS_PRE variable.

Re: [meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

I just checked your master branch and saw the updates on the pkgconfig and cmake files generation.

Either we make meta-qt5 look for the GLESv2 package config file to update properly the QMAKE_LIBS_EGL variable.
Otherwise we check in meta-raspberrypi that the meta-qt5 is enabled to feed EXTRA_QMAKEVARS_PRE.

Let's say that both options should work.
The first option could bring some patches to Qt mainstream.
The second is quite clean and easy to try.

I'll fork your branch and try out the second option.

- Have a nice day

Re: [meta-qt5][meta-raspberrypi]: QMAKE_LIBS_EGL not properly set

[GUEYTAT Julien]

Just to keep you informed that the compilation of Qt on top of the meta-raspberry stills need some work to pass with GLESv2 activated.
The EXTRA_QMAKEVARS_PRE variable can improve the situation... "QMAKE_LIBS_EGL = -lEGL -lGLESv2" get used during the compilation but NOT during the configuration. Which means that the configuration does not work and the bitbake qtbase fails.
I tried out the master branch of meta-raspberrypi with the pkgconfig updates on the userland.
And... It does not improve the configuration step.

I guess it is not so far because Qt is looking for those pkgconfig files which just means that they are not present yet during the configuration step.
So the question is:
How can you have those pkgconfig files get used during the Qt configuration step?
