Building pptk on Xavier, how to get through?

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier
1

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_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:

[ 86%] Built target estimate_normals

Hi,
Please take a look at the relevant posts:
Jetson Nano and Qt5 - #2 by WayneWWW
Pyqt not working on Nano - #4 by coolbot
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.

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?
