Any suggestions ?

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

[Pavel_47]

The log is quite huge, but concerning just before lines, here it is:

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

[Pavel_47]

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

[Pavel_47]

Hear is after clean and launching make:

ATSPI_STATE_READ_ONLY

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

[Pavel_47]

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

[Pavel_47]

@Pavel_47 said in How to build Qt on system without a GUI?:

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 ?

[jsulm]

@Pavel_47 said in How to build Qt on system without a GUI?:

Should they come from synchronization with RPi ?

Yes

[Pavel_47]

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

[Pavel_47]

The Raspberry Pi also could not locate these packages.

[jsulm]

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

[Pavel_47]

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)

[Pavel_47]

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

[Pavel_47]

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 ?

[jsulm]

@Pavel_47 said in How to build Qt on system without a GUI?:

In /usr/lib/x86_64-linux-gnu/libatspi.so.0
And Ubuntu provides the packages I mentioned above.
Debian should provide them as well (Raspbian is based on Debian), so you should be able to install them.

"Any suggestions ?" - well, something went wrong, there should be something in the log.

Yes I also have it on Ubuntu on the same location.
I also checked on Raspberry: it is there - in /user/lib/arm-linux-gnueabihf
But I didn't find it on Ubuntu - in ~/raspi/sysroot/usr/lib/arm-linux-gnueabihf, the folder which was synchronized with RPi.
Concerning your suggestion to look over log ... I didn't find any log file on rsync instruction. Nevertheless I look through over whole display buffer after erroneuous rsync execution (that didn't contain whole log !!!) and didn't find any error.

Hi,

If you can find the libraires/headers in your device root file system then using scp might be faster in your case to ensure you copy the files back to your machine.

Copied missed libraries from RPi to Ubuntu and rerun build.
Here is as it fails this time:

I've just tried once more resync the /usr/lib.
... and it failed immediately:
