Solved Raspberry Pi 3 B+ cross compile QT5
-
@dedetuga said in Raspberry Pi 3 B+ cross compile QT5:
What version of raspian stretch do you use?
The latest, always.
Right now I'm on Buster, but last time I compiled Qt for RPi, it was on Stretch.

I copy and paste the terminal output and share it here -> Full error
what can I do?
I'm having this kind of error every time I try build an cross compilethanks
-
There is no error in the output you pasted. Look earlier in the compilation log (because you are compiling with multiple threads, the logs are mixed, and the actual error can happen long before make will finish all threads), or run
make
again, without cleaning anything, and without-j
flag. Then the actual error should show up closer the end of the log. -
@sierdzio thanks for the tip, now I realize this is why I never can track the error! hahahahah!!! Embarrassing ...
any way I think is this you asked for:

Embarrassing ...
Don't worry, it's a common error to make.
Regarding the error - I don't think I've seen this one before, although I vaguely remember something similar. Looks like here somebody has found a solution: https://forum.qt.io/topic/88588/qtbase-compilation-error-with-device-linux-rasp-pi3-g-qeglfskmsgbmwindow-cpp/8
And this bug report suggests it is fixed in Qt 5.12 https://bugreports.qt.io/browse/QTBUG-68342
Unfortunately, each time Qt or RPi gets updated, issues pop up :-/

I read this one an hour ago when I google the error, and I have 2 replies that pop up to me:
@ambershark "I finally managed to get it compiled. I know it's not the pretty solution and that this may get back at me sometime, but for now it works. I run "make" with 2009 EGL version in place, then i replaced it with 2016 EGL version and run "make" again to compile file that failed. Finally I restored 2009 EGL. "
I have no idea how to play with versions of EGL, I don search it to much too yet.
@lirik90 "When i add this line: typedef EGLSurface (EGLAPIENTRYP PFNEGLCREATEPLATFORMWINDOWSURFACEEXTPROC) (EGLDisplay dpy, EGLConfig config, void *native_window, const EGLint *attrib_list); after all include in file src/plugins/platforms/eglfs/deviceintegration/eglfs_kms/qeglfskmsgbmwindow.cpp compile was finished great."
Where do I paste this line of code Makefile? which one?
And this bug report suggests it is fixed in Qt 5.12 https://bugreports.qt.io/browse/QTBUG-68342
I dont know how to handle bug reports but I will check
I'm able to find the file libEGL.so and libEGL.so.1.0.0 on my sysroot from my host ubuntu:
$ find ~/Qt-Cross-Compile/ -type f -name "libEGL*" /home/filipe/Qt-Cross-Compile/sysroot/opt/vc/lib/libEGL.so /home/filipe/Qt-Cross-Compile/sysroot/opt/vc/lib/libEGL_static.a /home/filipe/Qt-Cross-Compile/sysroot/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0
and on my pi:
pi@raspberrypi:~ $ sudo find /opt/vc/lib/ -type f -name "libEGL*" /opt/vc/lib/libEGL_static.a /opt/vc/lib/libEGL.so
but now I have no idea what to do.
However I changed a bit you config file, I read somewhere to try with EGLFS GBM so I changed linux-rasp-pi3-g++ to linux-rasp-pi3-vc4-g++:
../$QTVER-src/configure -device linux-rasp-pi3-vc4-g++ -opengl es2 -confirm-license -opensource -release -nomake examples -skip qtwebview -skip qt3d -skip qtquick1 -skip qtwayland -skip qtvirtualkeyboard -skip qtwebchannel -skip qtwebengine -skip qtscript -skip qtscxml -skip qtspeech -skip qtpurchasing -skip qtgamepad -skip qtserialbus -skip qtlocation -no-use-gold-linker -device-option CROSS_COMPILE=~/Qt-Cross-Compile/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/Qt-Cross-Compile/sysroot/ -prefix /home/pi/$QTVER-cross -extprefix ~/Qt-Cross-Compile/$QTVER-cross -hostprefix ~/Qt-Cross-Compile/$QTVER -v
And it compiled fine and installed fine.
I use rsync -avz 5.11.1-cross pi@raspberrypi.local:/home/pi/5.11.1-cross to send 5.11.1-cross folder to my pi.I set up my qt creator following this site, qhen I try to deploy I got:
22:56:53: Starting /home/pi/untitled2/bin/untitled2 ... QXcbConnection: Could not connect to display 22:56:54: Remote process crashed.
I add export DISPLAY=:0.0 to .profile file on my pi and reboot, try deploy again and new error:
23:01:59: Starting /home/pi/untitled2/bin/untitled2 ... MESA-LOADER: failed to retrieve device information MESA-LOADER: failed to retrieve device information MESA-LOADER: failed to retrieve device information 23:02:13: Application finished with exit code 0.
After some search I found ou this is not an error but a warning, then I look to my VNC window and I have it there, the beautiful window hello world!!!
I also Found out the breack point dont work, but I think I can do it localy
Thanks a lot for your help @sierdzio, I have no idea how I do it but It's working -
Well' I have no idea either, but good that it is working :D Happy coding!

After all my journey I decide try help other with this thing of compiling so I create a backup of everything and post it on web, you can download it here
It's a .rar file with 7.70 GB that contains backup ISO of my Raspberry pi 3B+ And the Cross-Compile folder debated on this topic, everything compiled and installed.You need just pass thru some steps to make it work in your Ubuntu (none of this steps are tested, but all the backup is real).
Cross-Compile setup Instrution:
On Host PC Ubuntu
(I used in Ubuntu 16.04LTS I dont know if will work in other version of ubuntu or linux):1- Unpack the .rar file to your home directory ~/
2- Flash the Raspberry Pi Image to your SD card using this command:sdd if=~/Raspberry_Pi_3B_Plus_Stretch_backup_15-07-2019_With_Working_QT5-11-1_Cross-Compile.img of=/dev/sdb bs=4M
Edit the path to the right ones, read more here https://www.htpcguides.com/easy-resize-and-back-up-raspberry-pi-sd-card-with-ubuntu/
I don't know if your SD card will be sdb it can have another name3- Run:
cd ~/Qt-Cross-Compile/qtbuild/
make -jnproc
install4- If no errors, go to your PI
On your Raspberry Pi 3B+
1- sudo raspi-config
2- select "7 Advanced Options" hit enter
3- select "A1 Expand Filesystem" hit enter
4- hit enter to "Ok"
5- select "<Finish>" hit enter
6- select "<Yes>" to rebootYou Pi is ready to go
Follow this link to configure your QTCreator https://wiki.qt.io/RaspberryPi2EGLFS on "Qt Creator" explanation and edit you link to begin with "~/Qt-Cross-Compile..." instead of "~/raspi..."
Example:
where say:
Go to Options -> Compilers
Add
GCC
Compiler path: ~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++you edit you path to be:
~/Qt-Cross-Compile/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-g++
I made this to help other with se same problem I have, read more in:
https://forum.qt.io/topic/104943/raspberry-pi-3-b-cross-compile-qt5/10 -
Hi. I pretty much cross-compile everything for my many PIs using multiple versions of Qt (although 5.13.0 seems to work rather nicely). I run a Fedora host, although there is no reason this shouldn't work equally as well on any other distro. (If you're running Windoze you're on your own ;)
It took a bit at first. I have a script at https://github.com/StevePunak/KanoopCommonQt/blob/master/docs/configqt which I use to do my initial configuration.
Modify the locations at the top to suit your build system, then run this script from your new shadow build location to do your configure
Three big tips to avoid unnecessary pain are:- Never build in source. Always use a shadow directory. Wherever you have the Qt source, make a directory for the build at the same level as Src/, and build there. You can rm -rf the contents of this shadow directory to get a complete clean
- Before you even start trying to build, fix the symbolic links on your PI directly by using the symlinks utility 'apt-get install symlinks' and running 'sudo symlinks -c .' in /usr/lib/arm-linux-gnueabihf and /etc/alternatives'
- If possible, DO NOT create a sysroot on your host. Instead use sshfs to mount your PI and use that as your sysroot. That way you will always be in sync when you install new dev packages on your PI. I can not tell you how much time that has saved me!
Hope this helps a little
