Cross Compile QT for Jetson Nano Problem

[mmeminb]

I am trying to cross compile Qt for Jetson Nano. I configured the build with these parameters:

../qt-everywhere-src-5.15.1/configure -opengl es2 -device linux-jetson-nano  -device-option CROSS_COMPILE=/opt/qt5jetson/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- -sysroot /opt/qt5jetson/sysroot -prefix /usr/local/qt5jetson  -opensource -confirm-license -skip qtscript -skip wayland -skip qtwebengine -force-debug-info -skip qtdatavis3d -nomake examples -make libs -pkg-config -v

when I tried to run make command I got error like below. I can’t find solution for this problem.

final link failed: Bad value
collect2: error: ld returned 1 exit status
Makefile:1227: recipe for target '../../lib/libQt5Core.so.5.15.1' failed
make[3]: *** [../../lib/libQt5Core.so.5.15.1] Error 1
make[3]: Leaving directory '/opt/qt5jetson/qt5build/qtbase/src/corelib'
Makefile:224: recipe for target 'sub-corelib-make_first' failed
make[2]: *** [sub-corelib-make_first] Error 2
make[2]: Leaving directory '/opt/qt5jetson/qt5build/qtbase/src'
Makefile:50: recipe for target 'sub-src-make_first' failed
make[1]: *** [sub-src-make_first] Error 2
make[1]: Leaving directory '/opt/qt5jetson/qt5build/qtbase'
Makefile:83: recipe for target 'module-qtbase-make_first' failed
make: *** [module-qtbase-make_first] Error 2"

How can I solve for this problem?

I am not a QT guy, and have not tried this compile. However, you should know that if ld failed, then your build was trying to link against a library somewhere, and the library was not found. Perhaps there is some system requirement library which needs to be added first. Or perhaps the library exists, but it isn’t in your linker path. Perhaps something else needed to be built first to create the library. I don’t know which library is missing, the message only says it was building libQt5Core.so.5.15.1 without saying what link was being attempted. Perhaps there is some log content prior to this naming the file/library which is missing?

Hi,
You may refer to the posts:

PySide2 (Qt for python) installation on Jetson Xavier

This issue was finally resolved, thanks to DaneLLL’s help. Here is the method to build Qt5 (and then PySide2 if you need Qt for Python) from source on Jetson devices: Download Qt source: if you need the whole Qt5 (~900MB): wget http://master.qt.io/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz or qtbase (basic module such as QtCore, QtGui and QtWidget)(~90MB): wget http://master.qt.io/archive/qt/5.15/5.15.2/submodules/qtbase-everywhere-src-5.15.2.tar.xz configure a…

Jetson Nano and Qt5

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 user…

Pyqt not working on Nano

ok, so I tried: sudo apt-get build-dep qt5-default sudo apt install libcanberra-gtk-module sudo apt install qt5-style-plugins echo "export QT_QPA_PLATFORMTHEME=gtk2" >> ~/.profile Then the problem solved… maybe this post can help:
