Building for ARM64

bruce_the_great

I'd like to build Qt applications for Linux Debian 10 Buster on arm64. (LXQt desktop)

Preferences in priority order:

Using Qt Creator natively.
Qt Creator on x64 cross compiling (from either Windows or Ubuntu)
Command line build, native.
Command line build, cross.

Are any/all of these options available?
Which would be the simplest to get working?
Which would be the best (for someone who hasn't recently done sophisticated configuration/builds)?
Can you point me to instructions for any of these?

Thanks!

Hi and welcome to devnet,

Just install the Qt development packages from the distribution package manager.
Yes that's possible, you need a proper cross-compiler
Same as 1 but without Qt Creator (which is using qmake to handle Qt project by default but can also do cmake or qbs)
Would be the same as 3 but using the qmake version built when cross-compiling Qt.

Duh! As simple as:
apt-get install qtcreator
and it even installed in the programming menu!

Thanks for the prompt reply!

It wasn't quite that simple. I also had to:
apt-get install qt5-default
and select a version for the "kit", as described here

Then, while parsing the .pro file, I got:
Project ERROR: Unknown module(s) in QT:charts

I'm not sure how to resolve that.

Qt 5 is splitted in several modules. I don't remember Debian providing an "install all Qt 5" package so you'll have to search the one you need and install them.

That did it. My app's running! :-)

friend tell me what should I do, really apt get can put qt or you built from src, and direct me if I need this thing for developers, where to put the sources, I have arm64 linux      @bruce_the_great
