Updating to Qt5.13 breaks EGLFS

[Mark81]

Some time ago I set up a Linux host to cross-compile Qt5 for RPi3. I used this configure command:

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/opt/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/opt/qt5pi -hostprefix ~/opt/qt5 -v -nomake examples -nomake tests -reduce-exports -no-pch -no-use-gold-linker

and I successfully cross-compiled Qt5.9 with EGLFS support. Now I want update to Qt5.13.
Today, I checked out the git repository and typed the same configure command. Here the configure output:

I don't understand why the OpenGL has failed this time. Perhaps I need to install some other libraries? When cross-compiling I always confused if I need to install library for my host on for the target... As side note, it's correct the specified device? I see other people use -device linux-rpi3-vc4-g++ (I want hw acceleration for omxplayer).

I don't know (I have not tried Qt 5.13 on RPi yet), but I may have some hints:

• install libraries for host (and then sync your sysroot)
• see if you can update your toolchain, GCC 4.8.3 is really old beast. Not sure if RPi have upgraded their official toolchain finally, but on a freshly setup RPi I have GCC 6.3.0
• use the vc4 device specs
• update the system on RPi and sync your sysroot
• run configure with verbose flag and see why OpenGL checks are failing. Maybe it's something simple and easy
• if all fails... downgrade to some older Qt version (5.11.x seems to work pretty good on Pi)

As side note, it's correct the specified device? I see other people use -device linux-rpi3-vc4-g++ (I want hw acceleration for omxplayer).

You should use vc4 for hardware acceleration (don't forget to turn acceleration on in raspi-config, too).

About this, it seems the "linaro" toolchain is still 4.8:

https://github.com/raspberrypi/tools/tree/master/arm-bcm2708

there is a "newer" gcc 4.9.3 but in the past I found that didn't work.

[sierdzio]

Ugh, that's so bad.

[Mark81]

I found this: https://github.com/ali1234/rpi-toolchain/releases, referenced here: https://github.com/raspberrypi/tools/issues/81.
It seems promising as the author says he was able to cross-compile Qt/QML but now I have to guess how to use it.

[Mark81]

I already have a working toolchain based upon Qt5.9 but I need at least Qt5.12 to use some features recently added.
After the whole days spent to download and build, here what I did:

• built cross-compiler toolchain (https://github.com/ali1234/rpi-toolchain), gcc now is 6.4.1 (linaro-6.4-2018.05)

• created from scratch a new base system using the latest Raspbian (2019-04-08)

• installed qt5 depencencies from testing (apt-get -y -t testing build-dep qt5-default)

• installed other depencencies (apt-get -y install omxplayer libssl1.0-dev libudev-dev libinput-dev libdbus-1-dev libglib2.0-dev libts-dev libx11-dev libx11-xcb-dev libxi-dev libasound2-dev fonts-dejavu gdbserver gdb-python2 libgles2-mesa-dev)

• created the sysroot as follow:

  1. copied the content of the sysroot output directory of rpi-toolchain to ~/opt/sysroot
  2. rsync -avz /mnt/rasp-pi-rootfs/lib ~/opt/sysroot
  3. rsync -avz /mnt/rasp-pi-rootfs/usr/include ~/opt/sysroot/usr
  4. rsync -avz /mnt/rasp-pi-rootfs/usr/lib ~/opt/sysroot/usr
  5. rsync -avz /mnt/rasp-pi-rootfs/opt/vc ~/opt/sysroot/opt
  6. sysroot-relativelinks.py ~/opt/sysroot

• run configure for Qt5 (same command above but with device linux-rpi3-vc4-g++)

Unfortunately, nothing has changed about EGLFS.
I tried to configure with verbose flag and saved the output to a file. Here the section where OpenGL fails:

Perhaps I just forgot a couple of libraries... but I cannot guess which.
By the way, I'm a bit confused about EGLFS, EGL, OpenGL ES 2.0/3.x... what should be the best one?

EDIT
I'm thinking that package libgles2-mesa-dev should not be needed, because EGL/GLESv2 drivers are already in sysroot/opt/vc/lib.

@Mark81 said in Updating to Qt5.13 breaks EGLFS:

/opt/vc/lib

This is not a standard path where the system is looking for libs/headers. I guess you will need to tell configure script to use it (don't forget that you need header files as well - this is what libgles2-mesa-dev contains).
