QuickTime & Creator on TX2

Thanks Dustin,
Now it is not tk1 but tx2.
Do we have an equivalent of
sudo apt-get install build-essential qt5-default qtcreator -y
or rather should be looking for a compiling from source for being able to program with qt\qtcreator?
Thanks
Andrey

Yes, these packages are available on TX2.

Really?
could you share your sources.list in case your execution of the command above succeeds, please?
In my case that returns : only the package qtchooser available

Doing:
git clone https://github.com/qt/qt5
cd qt5
./init-repository

You may have to enable multiverse [EDIT: in fact universe is required, not multiverse] :

deb http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted universe multiverse
deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted universe multiverse
deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports/ xenial-security main restricted universe multiverse
deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial-security main restricted universe multiverse

I had build-essential already installed :

sudo apt search build-essential
...
build-essential/xenial,now 12.1ubuntu2 arm64 [installed]

I have installed for being sure (had just checked with apt search till now) :
