QT5 Cross Compile for Raspberry Pi Tutorial

heedaf

Does anyone know of a Qt5 tutorial on setting up Qt with Raspberry Pi for cross compiling. I tried following http://wiki.qt.io/RaspberryPi_Beginners_guide but it seems to be removed since it seemed to be quite outdated.

This is the updated link for that guide: https://wiki.qt.io/Raspberrypi_beginners_guide

Thanks!

This seems to be the same one I tried earlier with dead links. I was able to download the toolchain but it seems to be a corrupted download since it won't tar. Is there another tutorial that works?

Hi and welcome to devnet,

Do you mean the toolchains from the github project don't work ?

I was final able to get the toolchain downloaded but now I'm having an issue with

                   cd ~/opt/qt5/qtjsbackend

but I get no such files or directory error and there is no qtjsbackend file in the qt5 directory.

Hi,

AFAIK, this one you have to clone manually

heedaf

After "cd~/opt/qt5/qtjsbackend" part nothing seems to work. Why is Qt5 such a nightmare when Qt4 installation was so easy? Does anyone know of another procedure that works?

SGaist

What exactly doesn't work ?

sudo apt-get install ia32-libs
Gives the following error

It runs ok up to "cd ~/opt/qt5/qtjsbackend" but I then I get the following error
-bash: cd: /home/pi/opt/qt5/qtjsbackend: No such file or directory

I also tried "git fetch https://codereview.qt.io/p/qt/qtjsbackend refs/cha
nges/56/27256/4 && git cherry-pick FETCH_HEAD" but it gave the following error

error: Couldn't resolve host 'codereview.qt.io' while accessing https://codereview.qt.i
o/p/qt/qtjsbackend/info/refs
fatal: HTTP request failed

I didn't go any further.

@heedaf said:

https://codereview.qt.io/p/qt/qtjsbackend

AFAIK, it's still https://codereview.qt-project.org/p/qt/qtjsbackend

heedaf

I tried using the address you listed (git fetch https://codereview.qt-project.org/p/qtjsbackend refs/changes/56/27256/4 && git cherry-pick FETCH_HEAD
and get the following error: fatal: remote error: Git repository not found

I just tried clicking on the link and it appears empty.

Any ideas?

You have a fork here But IIRC, that was for the v8 engine, so you shouldn't need it with a recent version of Qt
