[meta-qt5] Building and running issues on Raspberry Pi

[meta-qt5] Building and running issues on Raspberry Pi

[Felix01 Fischer]

Hello,
I'm trying to get Qt5 running on a raspberry pi using yocto and I'm facing 
two problems:
I'm using up to date layers from poky, meta-raspberrypi and meta-qt5

First, I have to add the following to local.conf (or a 
qtbase_5.X.Y.bbappend file)

QT_CONFIG_FLAGS += " \
    -device linux-rasp-pi-g++ \
    -device-option 
CROSS_COMPILE=$PATH_TO_SYSROOT_DIR/x86_64-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- 
\
    -I$PATH_TO_SYSROOT_DIR/raspberrypi/usr/include/interface/vcos/pthreads 
\
"

then I get the following error while "bitbake qtbase":

"DEBUG: Executing python function sysroot_cleansstate
DEBUG: Python function sysroot_cleansstate finished
DEBUG: Executing shell function qmake5_base_preconfigure
DEBUG: Shell function qmake5_base_preconfigure finished
DEBUG: Executing shell function do_configure

This is the Qt Open Source Edition.

A look into 
build/tmp/work/raspberrypi-poky-linux-gnueabi/qtbase/5.2.1-r0/qtbase-opensource-src-5.2.1/config.tests/unix/bsymbolic_functions.test

tells me that the "COMPILER" and "SYSROOT_FLAG" variables are empty. I 
don't know what to do here.
My workaround is to remove "-reduce-relocations" from QT_CONFIG_FLAGS in 
qtbase.inc

After that the build succeeds without problems.
But, when I boot up my image and try to run a Qt5 Application from the 
console I always get the same error:

"EGLFS: Unable to query physical screen size, defaulting to 100 dpi.
EGLFS: To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and 
QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
libpng warning: iCCP: Not recognizing known sRGB profile that has been 
edited 
EGL Error : Could not create the egl surface: error = 0x300b"

I'm stuck with this error and don't really know what to do.

Kind regards,

Re: [meta-qt5] Building and running issues on Raspberry Pi

[Diego Sueiro]

Are u running on X11 environment?

Do you have mali module and lib onto your system? I'm not sure if
meta-raspberrypi provides mali support. If not you fave to use a X11 image.

I had this same problem in another machine and I applied this patch to get
Cinematics Experience working with eglfs.:

Re: [meta-qt5] Building and running issues on Raspberry Pi

[Felix01 Fischer]

It's not possible to have hardware-accelerated QT on the raspberry pi when 
you are running an X11 environment, therefore I want to use eglfs 
directly.

The raspberry pi doesn't have a mali graphics core, AFAIK.

Nevertheless, applying your patch gives me an error while compiling.

"
[...]/qeglfshooks_stub.cpp: In member function 'virtual void* 
QEglFSHooks::createNativeWindow(QPlatformWindow*, const QSize&, const 
QSurfaceFormat&)':
[...]/qeglfshooks_stub.cpp:256:38: error: variable 
'QEglFSHooks::createNativeWindow(QPlatformWindow*, const QSize&, const 
QSurfaceFormat&)::mali_native_window native_window' has initializer but 
incomplete type
     static struct mali_native_window native_window = {
                                      ^
[...]/qeglfshooks_stub.cpp:261:1: warning: control reaches end of non-void 
function [-Wreturn-type]
 }
 ^
make[4]: *** [.obj/qeglfshooks_stub.o] Error 1
"

Any suggestions?

You are right. You should have to use userland package to get GLESv2:
http://git.yoctoproject.org/cgit.cgi/meta-raspberrypi/tree/recipes-graphics/userland/userland_git.bb

This patch just works for mali accelerated hardware.

I'm using this recipe and I think it's cooked into the image by default.
Just to be sure I will do another image with userland added via local.conf
I think if this would be missing I should get another error code, when 
trying to start a Qt Programm

You can search for a similar struct on Rpi libGLESv2 headers.

Till now I don't have any success.
Reading through various forums it seems to me, that with raspbian it is 
possible to get eglfs running.
But I haven't found any special patch or workaround they are maybe using.
Is there somehting special bitbake or poky does I'm not aware of?

Felix

Re: Antwort: Re: Antwort: Re: [meta-qt5] Building and running issues on Raspberry Pi

[Stephen Arnold]

I haven't really played with this end of rpi graphics much, but here are a
couple of things to check.  The vc-graphics, vg-graphics-hardfp, and
userland packages are all involved in rpi graphics.  The first two conflict
with each other, and there appears to be init scripts involved.  It looks
like maybe both userland and one of the vc-graphics packages are required
and some initial load/init stuff has to happen?  That's about all I got,
please post if you get it working.  My rpi build has nice working audio but
it would be cool to have full graphics support...

Thank you very much for your input!
Maybe yout got me going on the right path:

Going trough the meta-raspberry/recipes-bcm/vc-graphics [1]  folder I 
noticed something in line 10 in meta-raspberry/recipes-bcm/vc-graphics/
files/egl.pc [2]

"Cflags: -I${includedir}/vc -I${includedir}/interface 
-I${includedir}/interface/vcos -I${includedir}/interface/vcos/pthreads"

I always had to add "-I${includedir}/interface/vcos/pthreads" manually 
(mostly via "QT_CONFIG_FLAGS += " in  local.conf) otherwise qtbase won't 
compile, because it didn't find pthreads.

The commit message for egl.pc states
"This package adds a egl.pc file for use with libEGL (it is necessary to 
specify a custom include paths for the compiler due to brokenness in the 
firmware header files)." [3]

Maybe this is the root of my problems if qtbase and therefore my own 
programm and qtcinematicexperience aswell dont inherit this file and it's 
paths. Maybe my workaround has some nasty side effects.

Now I have to figure out how a *.pc file works with bitbake :-)

PS: I also needed to specify -device and -device-option CROSS_COMPILE= via 
QT_CONFIG_FLAGS. Maybe this should be done via meta-raspberrypi, too?

Regards,

Felix

Re: [meta-qt5] Building and running issues on Raspberry Pi

[Diego Sueiro]

Felix,

I don't if you could get Qt5 running on Rpi.

If not I suggest you to take a look at this recipe:
https://bitbucket.org/embarcados/meta-embarcados/src/434dc81fcb7fe630c107ef172afc33ce62e335db/meta-rpi/recipes-qt/qt5/qtbase_5.3.%25.bbappend?at=daisy

Note that vc-graphics is used instead of userland:
https://bitbucket.org/embarcados/meta-embarcados/src/434dc81fcb7fe630c107ef172afc33ce62e335db/meta-rpi/conf/machine/include/rpi-default-providers.inc?at=daisy

This is my bbblayers.conf:
BBLAYERS ?= " \
  ${TOPDIR}/../poky-daisy/meta-embarcados \
  ${TOPDIR}/../poky-daisy/meta-embarcados/meta-rpi \
  ${TOPDIR}/../poky-daisy/meta-raspberrypi \
  ${TOPDIR}/../poky-daisy/meta-qt5 \
  ${TOPDIR}/../poky-daisy/meta-openembedded/meta-oe \
  ${TOPDIR}/../poky-daisy/meta \
  ${TOPDIR}/../poky-daisy/meta-yocto \
  "

All layers in daisy branch and only meta-qt5 on master.

Additionally you have to set GPU_MEM = "128" on your local.conf.

I've tested the Cinematics Experience demo and everything is working like a
charm.
