How to build Qt on system without a GUI?

Pavel_47 · 28 Oct 2019, 13:47

Well ... I did it just before resync. Then, as I remember, after some manipulations with other staff, system proposed to remove unused files ... and I did it. Ok, I'll try to upgrade one more time. Then what should I check on RPi3, that xkbcommon package is latest version ?

please be aware that @jsulm is suggesting to update your OS, not just that library/package...

Latest Raspbian release is Buster

Yes, I understood the suggestion and upgraded system ... but being within "jessie". The Buster is quite new version, released 3-4 months ago. Ran Benita qualified xkbcommon staff, that caused problems and that originates from Raspberry (if my comprehension is correct), as "very very old". So, let's say in May 2019 (before Buster) it was impossible to install Qt toolchain ... or I missed something ? I've just checked upgrade to Buster ... according to some manual I've found on the web, it could take several hours. So, is it really necessary to upgrade to Buster ?

Has anyone managed to install Qt toolchain on Ubuntu that was synchronized with RPi running Buster ? If it's the case I will immediately buy new RPi4 and install Buster on it.

@Pavel_47 I plan to do so this week. I already have RPi4, but need to install Buster first. Can't tell you when exactly I will do all this. You can ping me end of week (if it is not that urgent :-)).

Pavel_47 · 11 Feb 2020, 11:30

Finally I've tried to build Qt toolchain for RPi4 using this tutorial:
Cross-Compile QT 5.12.6 / Raspberry Pi 4
Once more ... doesn't work.
Here is what I get while launching configure:

make[2]: Leaving directory '/home/pavel/qtbase/src/widgets'
make[1]: Leaving directory '/home/pavel/qtbase/src'
Makefile:50: recipe for target 'sub-src-make_first' failed
make: *** [sub-src-make_first] Error 2

Any suggestions ?

You did not post the actual errors - those should be before these lines.
Also, did you call configure from a clean state?

Concerning clean state ... probably not. Last time I tried with RPi3 three months ago and I don't remember the state of the system when I abandoned my attempts wit RPi3.
But I'll try once more after cleaning

Sorry, I've bee mistaken: the error occurred after make -j4, ... not after configure

Hear is after clean and launching make:

This belongs to libatspi. Do you have it and its dev package in your sysroot for RPi?

Pavel_47 · wrote on 12 Feb 2020, 10:52

You mean in sysroot/lib/ ?
No at that place there is no libatspi.

I've tried to install libatspi and libatspi-dev, but Ubuntu updater couldn't locate these packages. Should they come from synchronization with RPi ?

Yes

So, should I install them on RPi and then re-synchronize ?

Pavel_47 · 12 Feb 2020, 12:42

The Raspberry Pi also could not locate these packages.

jsulm · 2 Dec 2020, 12:42

@Pavel_47 My Ubuntu 18.04 has libatspi2.0-0 and libatspi2.0-0-dev
What is running on your RPi?

Pavel_47 · 13 Feb 2020, 07:12

My Ubuntu 18.04 has libatspi2.0-0 and libatspi2.0-0-dev
You have them in /usr/lib/ ?

What is running on your RPi?
Raspbian 10 (buster)

If I understood, you managed to build Qt toolchain for RPi4 on your Ubuntu. Is it correct?

The execution of one of the 3 resynchronizations (rsync -avz pi@yourpi:/usr/lib sysroot/usr to be exact) resulted in the following error:

sent 1,332,333 bytes received 119,470,015 bytes 1,320,244.24 bytes/sec
total size is 3,341,241,457 speedup is 27.66
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1668) [generator=3.1.2]

It’s probably related to the cause of make failure. I went up the log of synchronization, displayed on the screen but I did not notice any error.

Any suggestions ?
