How to build Qt and PySide2 on Xavier NX

ming_wu · October 6, 2020, 10:51pm

For some reason, I have to build both Qt and PySide2 on XavierNX

I have try to build them from apt-get but some errors occured

So I try to build the latest one

Did some one ever try to build Qt and PySide2 from source?

I want to know settings when configure and build Qt and PySide2

Hi ming_wu,

Qt is working on the Jetson system but sorry that we don’t have any experience with pyside2.
You can just give it a try: https://github.com/PySide/pyside2/wiki/Dependencies

Thanks.

Could you give me some guide on how to build Qt?

Hi @kayccc,
Did you know what will show after execute quickmwtest?
I didn’t get any widget from it

Hi,
It should pop up a window. Please check the source code:

github.com

alpqr/quickmwtest/blob/master/main.cpp

#include <QGuiApplication>
#include <QQuickView>
#include <QQmlEngine>
#include <QQmlContext>
#include <QScreen>
#include <QDebug>

static QQuickView *addView(QScreen *screen, int screenIdx)
{
    qDebug("Creating new QQuickView for screen %p", screen);
    QQuickView *v = new QQuickView;

    v->setScreen(screen);
    v->setResizeMode(QQuickView::SizeRootObjectToView);

    v->rootContext()->setContextProperty("screenIdx", screenIdx);
    v->rootContext()->setContextProperty("screenGeom", screen->geometry());
    v->rootContext()->setContextProperty("screenAvailGeom", screen->availableGeometry());
    v->rootContext()->setContextProperty("screenVirtGeom", screen->virtualGeometry());
    v->rootContext()->setContextProperty("screenAvailVirtGeom", screen->availableVirtualGeometry());

Probably you don’t disable X server correctly:

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