How to build Qt on system without a GUI?

Pavel_47

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.

jsulm

@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

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?

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 ?

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

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 ?

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.
