Can't build Qt for Tinkerboard?

redknight106

Hi,
I like many others are trying build qt for asus tinker board according to this qt blog post:
https://blog.qt.io/blog/2017/05/03/qt-git-tinkerboard-wayland/

I have spent quite some time going over this with no results. As the guide cross references another guide (https://wiki.qt.io/RaspberryPi2EGLFS) it could become easy to make a mistake. To help I have included a short guide of what I've done.

Loading QT on to Asus Tinker

http://blog.qt.io/blog/2017/05/03/qt-git-tinkerboard-wayland/#comments
https://wiki.qt.io/RaspberryPi2EGLFS

Download latest Cross-compiler for x64
https://releases.linaro.org/components/toolchain/binaries/6.3-2017.02/arm-linux-gnueabihf/

Extract and rename to 'toolchain' and place into /tinker folder

Download latest “wayland” variant from the Firefly RK3288 section
https://developer.arm.com/products/software/mali-drivers/user-space

[on Tinker] copy EGL/GLES/GBM/wayland-egl libraries to /usr/lib/arm-linux-gnueabihf.

1)[on Tinker] Install a bunch of development files (for simplicity we use build-dep, not everything is really needed, but it is easier this way). 
	
	A- Disable auto-starting X
		Command = sudo systemctl set-default multi-user.target or systemctl set-default graphical.target (to restore GUI)
	1- Edit sources list in /etc/apt/sources.list with use of your favorite editor (nano / vi) and uncomment the 'deb-src' line:
		Command = sudo nano /etc/apt/sources.list
	2- Update your system and install required libraries:
		Command = sudo apt-get update
		Command = sudo apt-get build-dep qt4-x11 libqt5gui5 wayland weston.
	3- Prepare our target directory
		Command = sudo mkdir /usr/local/qt5
		Command = sudo chown linaro:linaro /usr/local/qt5
 	4- Give Root Password
		Command = sudo passwd root
		Command = Password
		Command = Password

2)[on Host] Create a sysroot on the host:
	
	Command = rsync -avz linaro@192.168.0.48:/lib ~/tinker/sysroot
	Command = rsync -avz linaro@192.168.0.48:/usr/include ~/tinker/sysroot/usr
	Command = rsync -avz linaro@192.168.0.48:/usr/lib ~/tinker/sysroot/usr

3)[on Host] Make all symlinks relative:	
	
	Command = cd ~/tinker
	Command = wget https://raw.githubusercontent.com/riscv/riscv-poky/master/scripts/sysroot-relativelinks.py
	Command = chmod +x sysroot-relativelinks.py
	Command = ./sysroot-relativelinks.py sysroot 
	
4) [on Host] Configure with -device linux-tinkerboard-g++: 
	
	Command = git clone git://code.qt.io/qt/qtbase.git -b dev
	//or
	Command = git clone git://code.qt.io/qt/qtbase.git -b 5.10
	
	Command = cd qtbase
	Command = 	./configure -release -opengl es2 -nomake examples -nomake tests -opensource -confirm-license -v \
				-device tinkerboard -device-option CROSS_COMPILE=~/tinker/toolchain/bin/arm-linux-gnueabihf- \
				-sysroot ~/tinker/sysroot -prefix /usr/local/qt5 -extprefix ~/tinker/qt5 -hostprefix ~/tinker/qt5-host
				
	Command = make
	Command = make install

5)[on Host] rsyn to tinker
	return to /tinker
	Command = rsync -avz qt5 linaro@192.168.0.48:/usr/local
	
6)[on Host] Set up QT device and Kit.

After setting up Qt and creating the device and kit when I build the project I get 200+ errors

If someone could confirm if this is a problem with my hybrid guide or I have missed something important please tell me as I would like to include this into another blog or yours to help others.

Thank you for your time.

Kind regards

Hello,
Which version of tinkeros and qt are you using?

vladstelmahovsky

I think, the best option to bundle linux+qt on tinkerboard is to use Yocto with meta-qt5

Milad

I agree with you. i ran into exactly same problem you mentioned in your post.

Can you please tell me your steps through Yocto Qt?
because there are some tutorials on rock-chip website for (rk3288) but i don't know if its compatible with tinker board.
Thanks.

Milad

BTW.
I could finally fix the problem by adding "DISTRO_OPTS += deb-multi-arch" to qmake.conf in qtbase/mkspecs/devices/linux-tinkerboard-g++

#
# qmake configuration for the Asus Tinkerboard (Rockchip RK3288, Cortex-A17, Mali-T764)
#
# This configuration targets eglfs via DRM/KMS and Wayland.

DISTRO_OPTS += deb-multi-arch

include(../common/linux_device_pre.conf)

QMAKE_LIBS_EGL         += -lEGL
QMAKE_LIBS_OPENGL_ES2  += -lGLESv2 -lEGL
QMAKE_LIBS_OPENVG      += -lOpenVG -lEGL

DISTRO_OPTS            += hard-float
COMPILER_FLAGS         += -mtune=cortex-a17 -march=armv7-a -mfpu=neon-vfpv4

# Preferred eglfs backend
EGLFS_DEVICE_INTEGRATION = eglfs_kms

include(../common/linux_arm_device_post.conf)

load(qt_config)
