Hi sqwer6545,
Yes, that is the linux arch issue because jetson Nano is using arm64.
I tried to build qt5 last year on my TX2. The steps should be similar. Please note that this is not cross compile case.
For cross compile, I think you could refer to qt official website.
https://doc.qt.io/QtForDeviceCreation/qtee-preparing-hardware-jetsontx1.html
Download the backend from public source
wget http://master.qt.io/archive/qt/5.9/5.9.2/single/qt-everywhere-opensource-src-5.9.2.tar.xz
#Some users suggest to install below libraries before configure.
https://wiki.qt.io/Building_Qt_5_from_Git
untar qt tarbell
tar -xpf qt-everywhere-opensource-src-5.9.2.tar.xz
cd qt-everywhere-opensource-src-5.9.2
./configure
Choose "o" when the prompt asks which version of Qt you want to install.
Check if EGL and EGLFS is enabled

make -j4
sudo make install
# 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 service lightdm stop (because we are demo DRM usecase)
