QOpenGLWidget example doesn't start on Raspberry Pi

kickoune103

hello i have followed this tutorial to install qt5.8
https://wiki.qt.io/RaspberryPi2EGLFS
build full qt5.8 no problem
i have problem when i start qopenglwidget example.

i have add the link to my qt library in /etc/ld.so.conf.d/qt5pi.conf
(for my /usr/local/qt5_8pi) and sudo ldconfig

i have pi@raspberrypi:/usr/lib/arm-linux-gnueabihf $ sudo ldconfig

@kickoune103 if you run "file" on the libraries, what does it say that they are ?

jsulm

@kickoune103 Are you sure you built Qt for Rasperry Pi (for ARM) instead for your PC X86_64?
You can check that calling

file /usr/local/qt5_8pi/lib/libQt53DLogic.so.5

on your Raspberry Pi.

kickoune103

example:
pi@raspberrypi:~ $ sudo file /usr/local/qt5_8pi/lib/libQt53DLogic.so.5
/usr/local/qt5_8pi/lib/libQt53DLogic.so.5: data

kickoune103

yes 64bits...

-device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- \

oniongarlic

Something must have gone wrong in your build. Did you build on-device ?

kickoune103

no cross compiling like this :

Ok, I do all my builds on-device.
But, check that the library files produced on your build machine are ARM binaries, use file for example, should respond with something like:

ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV) .

and if not, then your build environment is broken.

And check that they don't break when do transfer them over to your Pi.

in my pi:
root@raspberrypi:/usr/local/qt5_8pi/lib# file libQt5Gui.so.5.8.0
libQt5Gui.so.5.8.0: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, BuildID[sha1]=4bcd5c6b508a7f287465b546df892a89b8cb6867, stripped

i have copied in USB disk FAT32, symbolink link was disapeard! no error in linux!

my virtual machine not work in ssh at my work, but work fine at home...
so i copy in usb at work.

kickoune103

export LD_LIBRARY_PATH=/usr/local/qt5_8pi
example opengl running but no font in qt5_8pi/lib/font ..... is empty !!!!

jsulm

@kickoune103 FAT32 never heard anything about symbolic links - you should use a Linux file system, not FAT32.

kickoune103

lib font is empty

i have install
libfontconfig1-dev
libfreetype6-dev

problem!!!!!

@kickoune103 Please call configure with additional -v parameter. Then you will see what exactly is missing.

kickoune103

-v it's use before.
V5_8 works with my pi2 in cross compil.

$LD_LIBRARY_PATH="/usr/local/qt5_8pi/lib" (for me)
$QT_QPA_FONTDIR = "/usr/share/fonts/truetype/dejavu"

for works with this tutorial:
https://wiki.qt.io/RaspberryPi2EGLFS

it's work less fontconfig with my previous image.

jsulm

@kickoune103 said in error after start example qt5.8 for raspberrypi:

-v it's use before.

Then please post the actual configure output (at least the part where fontconfig is being tested).
