QT support in Libreelec

titusece · February 27, 2017 at 2:04 PM

Dear All,

How can I enable the QT support in libreelec ?
Want to run QT5 examples on my Amlogic board.
Can you please help me ?

Regards,

Hello,
Able to build QT separately and how can I build it with image ?
PROJECT=S805 ARCH=arm ./scripts/build qtbase

Also please help me to build "gstreamer" and "qt-gstreamer" plugins ?

Regards,
Titus S.

The package.mk below builds qt-everywhere (which includes qt-gstreamer).
Building other packages with qt5 (qtbase/qt-everywhere) will however fail like for example this.
Maybe lrusak can help further.

qt-everywhere builds.

Using cmake to build QT applications will however fail, due to this.

config/make/make install, if possible, works, see eg here.

Thanks for this!

are you compiling in 32 or 64bit?

Have you have any luck compiling 5.8.0 ? it fails for me

I am building with Ubuntu 16.04 LTS 64-bit.

Why do you need 5.8.0?

I am also using Ubuntu but what I meant is it LE Arch64 or ARM? I can't seem to be able to compile qt-everywhere, not even 5.6.2, I use arch=arm

The reason I want 5.8 is because I want to try a emulator frontend called pegasus, that needs 5.8

Ah, yes: qt-everywhere builds for vanilla LibreELEC projects, not for SX05/arm.

I will see what I can do, do not hold your breath though

**thoradia** · May 27, 2017 at 10:00 PM

qt-everywhere 5.8.0 builds for S805, and should build for all other projects.

Well it seems it is something on my side as I get the same error I got when I tried before

I am using Kszaq's build, but I am using the PROJECT=S905, not sure why it won't build for me anyways, thanks for the help I am going to keep looking and see if I can find the reason.

I found this, not sure how to fix, though: [RFC,2/2] qt5base: fix build issue on 32bits armv8 target - Patchwork. Maybe kszaq or GDPR-1 can help.

I've been using that patch and it seems it gets further down the build but it still fails.

is it an exact clone of Kszaq's build? I've been trying with PROJECT=S905 and S805 both of them fail at the same spot.

cd LibreELEC.tv
git checkout thoradia-SX05-8.0

I trust branch thoradia-SX05-8.0 is based on a recent kszaq release.

Thank you, still doesn't build for me which is extremely weird it has to be something on my side.

Well I give up on trying to compile QT for LE. I reinstalled everything on my build laptop, and the build still fails even with your repository, so I have no idea what is going on.

Thanks for all the help!

Edit: Well on my last try I finally got it, I had to dissable a bunch of modules I didn't need and now it compiles.

Great! Which modules? Tell us!

I am doing a clean build of everything and as soon as it finishes I will push the package to my repo and share it
