eglfs + framebuffer - display issue

python74

What You mean by incomplete?

SGaist

In verbose mode, the configure script prints way more lines than what you have here.

Did you re-run configure from a clean state ?

python74

before config i did make clean all

SGaist

You just cleaned the build artefacts not the configuration stuff. You should do out of source builds, that way you can just nuke the build folder if something fails and the source will stay clean.

python74

Thanks. How to do build to another dir?

jsulm

@python74

mkdir build
cd build
PATH_TO_QT_SOURCE/configure ...
make

python74

Thanks for help. But i have another problem. I removed old src directory an was trying to compile qt again. And then problem starts - running configure script and instead make shell trying to use /usr/lib/x86_64-linux-gnu/qt5/bin/qmake wchich btw i removed wit previous QT. Qt5 was installed with qt creator. How to avoid that?

@python74 said in eglfs + framebuffer - display issue:

instead make shell trying to use /usr/lib/x86_64-linux-gnu/qt5/bin/qmake

Sorry, I don't understand that: if you try to call make qmake is called or what? Can you please explain better (show the steps you did)?

python74

Sorry, I'm not good with english.
Right now i'm in work so i can't post output from console.
Previously I compiled qt with bad options (running configure command without some parameters), but also installed qt creator from repository (apt-get). Later I removed whole directory with qt source, and made new with clean sources. Inside new sources directory I have launched configure script in terminal. Process starts with qmake build, but stops with error: load(qt_config) not recognized (or similar - i'll post output after work). So in console i typed "make clean all" and then instead make shell calls /usr/lib/x86_64-linux-gnu/qt5/bin/qmake. Then I removed all qt from system with qt5 directory via apt-get an nothing changes - cant run configure script because of calling non existing /usr/lib/x86_64-linux-gnu/qt5/bin/qmake. I've exported MAKE=/usr/bin/make - still error: load(qt_config)

You should start by cleaning things.

Delete your current Qt sources and then uncompress the archive again so you are really in a clean state to build.

Then, as suggested make an out of source build like @jsulm showed.

When you want to use qmake, use the full path to the executable. The one found by your console is the system installed qmake and it's currently not the one you want to use.

python74

my point is i removed qt5 (with qmake) installed in /usr/lib/x86_64-linux-gnu/qt5/bin/qmake, but still make command points to this particular qmake

jsulm

@python74 Please do a clean rebuild first! Old Makefiles will still point to that old qmake as they do not know that you removed it.

python74

You mean remove makefiles from qt source directory? I deleted whole directory and unpacked sources fro zip again

python74

thanks very much guys. I know im pain in the ass but explain me please one more thing: A20 have mali GPU. After config i have:
QPA backends:
DirectFB ............................... no
EGLFS .................................. yes
EGLFS details:
EGLFS i.Mx6 .......................... no
EGLFS i.Mx6 Wayland .................. no
EGLFS EGLDevice ...................... no
EGLFS GBM ............................ yes
EGLFS Mali ........................... no
EGLFS Raspberry Pi ................... no
EGL on X11 ........................... yes
LinuxFB ................................ yes
VNC .................................... yes
Mir client ............................. no

Why scripts dont recognize mali? It is a way to enable it? like ie CFG_EGLFS_MALI=yes

SGaist

You have to use your device sysroot. If you are using the one provided by Linaro, it won't contain the specifics for your target.

Hi
After few nights of work finally done. I've cleared all files and run compile process on new sources so I have now Qt5.9.1. Very important: on sunxi linux with Allwinner A20 you need to change:

qtbase/src/plugins/platforms/eglfs/api/qeglfsdeviceintegration.cpp

EGLNativeWindowType QEglFSDeviceIntegration::createNativeWindow(QPlatformWindow *platformWindow,
const QSize &size,
const QSurfaceFormat &format)
{
Q_UNUSED(platformWindow);
Q_UNUSED(size);
Q_UNUSED(format);
//return 0;
static struct mali_native_window native_window = {
.width = (short unsigned int)size.width(),
.height = (short unsigned int)size.height(),
};
return &native_window;
}

or eglfs fails.
Thank You guys veeery much for help and Your patience
Regards
