SVG in QPushButton on RPi

mazurs

Hi,
I configured my computer to cross compiling based on RaspberryPi2EGLFS (https://wiki.qt.io/RaspberryPi2EGLFS) to write programs on RPi.

My application run on fullscreen so I use SVG file in QPushButton. When I run program on computer icons appear well but when I run on RPi icons are missing.

When I use png or jpg icon appear but is small (icon is not scales).

I try to set QT += core svg gui but I get error Unknown module(s) in QT: svg.

Does anyone know how to solve this problem?
Thank you in advance for your help.

Hi and welcome to devnet,

You have to cross-compile/instal the qtsvg module.

Thank you for your reply.

I have checked and I have not qtsvg folder in qtbase.

So, I cloned once again qtbase and made ./configure but still I don't have qtsvg.

git clone git://code.qt.io/qt/qtbase.git -b 5.6
cd qtbase

./configure -release -opengl es2 -device linux-rasp-pi-g++ \
-device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- \
-sysroot ~/raspi/sysroot -opensource -confirm-license -make libs \
-prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

After configure I get output:

What am I doing wrong?

SGaist

You are cloning the wrong module, QtSvg has its own module. Once you cloned it, you can use your cross-compile qmake to build it.

Thank you for help :-)

I cloned whole qt5 and initialized only qtbase and qtsvg.
To compile I had to install libxcb-xinerama0 libxcb-xinerama0-dev on RPi and sync systool.

Everything work well!
