Ubuntu Touch Programming Course

TischlerWilly

Great that you write this tutorial for us

I have follow the instructions to install the SDK.
So far so good.
but i can not install the developer kitś.
I get every time the following error message:

Creating image with: framework: ubuntu-sdk-15.04 arch: amd64
error: No storage pool found. Please create a new storage pool.
---Task exited with errors, please check the output---

Why it can not find the pool? Have I forgot something?
System is up to date.
Ubuntu SDK IDE is installed.
PPA is added.
Iḿ in the usergroup lxd.
PC is restarted

What version of Ubuntu are you using?

TischlerWilly

Linux Mint 18 Cinnamon 64-bit

Have I to use the Ubuntu Gnome Desktop?

@TischlerWilly,

It may be a particular Linux Mint bug. This weekend I can create a virtual machine and check if I can replicate the bug. The course I'm programming in Ubuntu 16.04 with the Mate desktop (although it should work with any desktop).

Hi guys.

At the end of the week I'll be uploading the resources I used at Ubucon Paris 2017. The virtual machine uses Ubuntu Mate 16.04 and has the SDK ready to work. Just download the file, configure VirtualBox and start programming applications.

The link to the presentation is temporary, when I publish it I will update the link.

I hope at the end of the month to upload the translations of several course sessions. My intention is to match the Spanish and English versions before continuing with the new content.

Good afternoon.

You can now download the resources I used in the UbuconParis 2017 workshop. The virtual machine has the following features:

Ubuntu 16.04 with the Mate desktop.
SDK already configured with IDE icon on the desktop.
The workshop exercises are saved in the User Folder.

The credentials are:

User: ubucon
Password: ubucon

Links are public. I would ask you to download the resources using the short link because that way I can have some statistics.

It is possible, in the future, to add new elements to the virtual machine. It all depends on the suggestions you make. If you have any problems with the file you can indicate it in this thread.

I hope to publish new translations of the course next week. When the English and Spanish versions are ready, I will create new content.for both.

Hi,

It seems that the link to the VirtualBox VM is down...
Could you provide it again?
Thanks
W.

Hi @wilfridd. I've fixed the link, check again.

@mimecar
That's ok! Many thanks

Thank You. Works great!

Is it possible to run an „only“ C++ projekt with qt and on the device? I need, for example, the QNetworkAccessManager, its only in c++. If I try to compile it, it says „no executable found“... Thanks for help.

mimecar

If it is a C++ project that needs external libraries, you have to add them to the project configuration. Did you do it? Is the application running well on your PC?

Tewel

@mimecar Hello, thank you for helping. Im not sure. There are 3 modes: 1. Desktop: it works fine 2. UbuntuSDK for Desktop, it does not work, whants me to give him the executable „please specify one“ the 3. UbuntuSDK for device, I didn‘t tried yet. How do I give him the right libs? And where? Is there a documentation? I don‘t know exactly what I should search for to get the specific instruction... My experiences are only with visual-studio... and not cross anything :0) But I would like to get through this...

mimecar

Hi, @Tewel,

So far I have only worked with QML and JavaScript. If you send me the project you want to compile (with the minimum code the library uses), I'll check it over the weekend.

Tewel

@mimecar Thank you, thats a nice offer! You led me to a thing I whant to try first „Integration of qlm and c++“ there is a documentation. In the web are some hints that its nessesary to do this first, if you whant to use c++ with qml and ubuntu. But there was no time until now to figure it out. I will tell if its the solution....

Tewel

@mimecar Ok, the Connection of QML with c++ was needed first. Found a very helpfull Tutorial https://www.youtube.com/playlist?list=PLfkTJXI2Tk-e6Px7PRXvMxT6tH8e7rQ9i
Thank you for helping.

mimecar

Ok @Tewel, I will check your link.

I'm trying to get ubuntu-sdk running on my laptop.System is Ubuntu 16.04.
I have followed your guide. I get following errors when trying to start ubuntu-sdk...

Stopping containers: All containers stopped. Creating default network bridge ..... FAILED 
error: Creating the bridge failed with: not implemented 
—-Task exited with errors, please check the output---

And next popup says..

qtcreator: Setting up the container backend failed.

Hi @HendriXXX
NOT sure if it is the solution, but take a look at this: https://insights.ubuntu.com/2016/04/07/lxd-networking-lxdbr0-explained/
Looking at that document running from a shell: sudo lxd init could be useful.
Otherwise (the simple solution) is download the virtual machine already configured with the sdk
using the link that you can find in this thread published by mimecar.
