Building pptk on Xavier, how to get through?

Steps to reproduce:
Install dependencies

sudo apt install qtbase5-dev qttools5-dev-tools qt5-default
sudo apt install libtbb-dev
sudo apt install patchelf
sudo apt install libeigen3-dev
git clone https://github.com/heremaps/pptk
mkdir build && cd build

put the paths to the file CMakeCache.txt

Eigen_INCLUDE_DIR:PATH=/usr/include/eigen3
Numpy_INCLUDE_DIR:PATH=/usr/local/lib/python3.6/dist-packages/numpy/core/include/numpy/
Qt5_DIR:PATH=/usr/lib/aarch64-linux-gnu/cmake/Qt5
TBB_INCLUDE_DIR:PATH=/usr/include/tbb
TBB_tbb_LIBRARY:FILEPATH=/usr/lib/aarch64-linux-gnu/libtbb.so

TBB_tbbmalloc_RUNTIME:FILEPATH=usr/lib/aarch64-linux-gnu/libtbbmalloc.so

build with

cmake -DOpenGL_GL_PREFERENCE=GLVND ..
#or just cmake ..
make -j8

the error tail output:

Hi,
Please take a look at the relevant posts:
Jetson Nano and Qt5
Pyqt not working on Nano
Not sure but these might help.

And we have tried this app in qt environment:

#  Download a sample and build
https://github.com/alpqr/quickmwtest
#If you don't configure the installation path, you need to create a link.
sudo ln -sf /usr/local/Qt-5.9.2/bin/qmake /usr/lib/aarch64-linux-gnu/qt5/bin/qmake
# Use "qmake" under sample folder and then "make" 
# If you hit qmake error  →     export QT_SELECT=qt5

#Before running the sample 
$ sudo systemctl stop gdm
$ sudo loginctl terminate-seat seat0
unset DISPLAY
export QT_QPA_PLATFORM=eglfs
export QT_QPA_EGLFS_INTEGRATION=eglfs_kms_egldevice
./quickmwtest

May check if you can build/run the sample.

Embedded (eglfs) test app for Qt 5.9's new Window.targetScreen and Qt.application.screens properties.
(see http://doc-snapshots.qt.io/qt5-dev/qml-qtquick-window-window.html#targetScreen-prop and http://doc-snapshots.qt.io/qt5-dev/qml-qtqml-qt.html#application-prop)

This is very handy when working with QQmlApplicationEngine and specifying Window
elements in QML, instead of constructing QQuickWindow instances from C++.

For now we assume there are at least two screens, and create a Window (i.e a
separate QML scene) for each of the first two.

U meant like that? @DaneLLL

Hi,
Sorry the commands for disabling display manager should be

$ sudo systemctl stop gdm 
$ sudo loginctl terminate-seat seat0 

Have corrected it. Please try and check if you can see display output.

both displays got black
no console prompt
will try restarting


after restart
second attempt

Hi,
Sorry for the late. We get the layout like:

@DaneLLL
Thank you for following up.
I can repeat it. suceeded at nx.


it wont support USB c display though in init 3 mode. I am just wondering if Is it possible for USB-C display to work without gdm?
However, I did not find a way to press the exit button.
Moreover, it seems that I need to apply it somehow to build pptk, right?
