Re: Getting started with Kubuntu development.

They're not exactly the same, Ubuntu and its relatives are Debian based but not equal to Debian. That's why some Debian packages don't work on *Ubuntu... Sadly, I don't know how to code according to Kubuntu's specs. I guess you'd need to either code in KDE (kdevelop) or Qt (to make sure it might be compatible with all KDE based GUI distros). Maybe GreyGeek knows more about this.

Re: Getting started with Kubuntu development.

thanx kyonides.

I wasn't making much progress with

http://www.debian.org/doc/maint-guide/ch-first.en.html

so I headed down a different path

https://wiki.ubuntu.com/MOTU/GettingStarted
https://wiki.ubuntu.com/PackagingGui.../PackageUpdate

MOTU seems to be another way of building packages. I was able to perform Method steps 1-8 in Recipes only by replacing

debuild -S -sa

with

debuild -i -us -uc -S

The latter, as best I understood, built the dsc without signing it with a private key. Every time I tried the former, it failed complaining that there was no available private key. I looked at gpg and ran gpg --gen-key. It seems to leave its results in ~/.gnupg however this didn't seem to help. That is, when I ran the dsc build again it still didn't find a private key.

I didn't know if leaving the private key out would work but continued anyway.

Finally got to Step 8 (the last) and the command (sudo pbuilder build brasero_0.6.1-0ubuntu1.dsc) ran fine except that I find no result in

/var/cache/pbuilder/result

So what is brasero anyway?

alt-f2 (run) brasero. It's for burning CDs and such. What does Help | About tell me? My installed version is 2.30.1 so the code I'm trying build from the instructions (a combination of 0.5.2 and 0.6.1) seems to be very old.

**patfla** · Jun 15, 2010, 03:33 PM

Re: Getting started with Kubuntu development.

As I go through the slew of messages that

sudo pbuilder build brasero_0.6.1-0ubuntu1.dsc

puts out, the following caught my eye:

Code:

.
.
.
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
Reading package lists... Done       
Building dependency tree    
Reading state information... Done
Reading extended state information   
Initializing package states... Done
Writing extended state information... Done

Current status: 0 broken [-1].
Aptitude couldn't satisfy the build dependencies
E: pbuilder-satisfydepends failed.
.
.
.

So now I'll try and figure out what this is telling me.

Re: Getting started with Kubuntu development.

I am NOT a (*)buntu Developer, (although I've been writing software for 50 years), so this advice may be totally worthless. That said:

(1) (*)buntu is based on Debian so the place to start is the Debian New Maintainers Guide. This will teach you about packaging.

(2) Kubuntu is based on the KDE software compilation. KDE is written (primarily) in C++, using a development system called "Qt". (Actually, there is an offshoot called "Kdevelop", but this is a global view.) If you want to generate GUI programs for KDE, learn Qt.

(3) Most of the software that distinguishes the (*)buntu distributions from Debian is written in Python, (Mark Shuttleworth, the originator of Ubuntu, is a ferocious Python hacker.), so Python is another essential.

(4) Start small.

Remember, "Use the source, Luke!"

Actually I'd already gotten stuck trying to use an example from that page (Debian New Maintainers Guide).

I know python (and C++ as well) so that'll work..

I started on this whole exercise with openSUSE running in VirtualBox on Windows 7. Where I built kcalc from source which was small and simple.

I then switched to making a dual boot with kunbuntu and Windows 7 and am trying to get my bearings again

Remember, "Use the source, Luke!"

Think I found what I needed:

General
http://techbase.kde.org/Getting_Started/Build/KDE4
kubuntu-specific
http://techbase.kde.org/Getting_Star...ntu_and_Debian

I needed to look at the pages at KDE (where I'd already been when on openSUSE) - and not at Kubuntu pages. Which I find a little surprising, but whatever.

**kyonides** · Jun 15, 2010, 07:10 PM

Re: Getting started with Kubuntu development.

Not that surprising once you know, like I recently do, that the main difference relies on using python as much as possible or if deemed necessary...

Then, there's no need to think too much on which KDE distro you're aiming to if you need to learn programming "with" Qt (C++ headers, modules, etc. already available, predesigned).

I was recently trying to compile a port of Asteroids or KAsteroids. I compiled it using sidux but when I logged onto Kubuntu I was surprised due to the fact I could run it on Kubuntu, too. I guess that's what Qt developers (former Trolltech now some Nokia dev group) pretended from the very beginning.

Re: Getting started with Kubuntu development.

You might want to "sudo apt-get install qt-sdk" in terminal window. Run qt-creator from the development menu. This will be as close to visual studio as you will come on linux (assuming that is what you are used too).

Re: Getting started with Kubuntu development.

And don't forget to pop into irc on freenode and chat about things with the folks on #kubuntu-devel, as well as many other chat channels and other resources they can point you to

**patfla** · Jun 16, 2010, 12:25 PM

Re: Getting started with Kubuntu development.

Hi claydoh. I'm not real familiar with IRCs but I found; downloaded and installed konversation.

Server = irc.freenode.net

And I'm now connected to #kubuntu-devel. There are 188 connections (nicknames) at the moment. I posted the following about 20 minutes ago:

Code:

[10:53] <patfla> kdebase trunk runtime/nepomuk/services/queryservice seems to be broken at the moment?

There are 1 or 2 other conversations going on but no one has responded to the above. So I'll wait but anyway this is what I'm seeing.

Code:

At revision 1138778.

Files in kdebase/runtime/nepomuk/services/querysevice have been broken, in one way or another, for the last 12 hours (since last night for me).

I can confirm here:

http://websvn.kde.org/trunk/KDE/kdeb...s/?sortby=date

that someone is working on the code

Is there some way of rolling back to an earlier (hopefully working) version? Of say, queryservice. I've tried svn update with version numbers (-r number) but so far that hasn't worked.

(Preview - hmm looks like long line lengths in the quotes will push the window way out to the right ... must be some way of fixing that).

**claydoh** · Jun 16, 2010, 12:47 PM

Re: Getting started with Kubuntu development.

you can ask a question, or at least ask where your question might be answered in another kde channel Kubuntu devs don't actually write the code, at least in the case of nepomuk. I am sure there is a nepomuk channel of some sort, or a kde channel where that is discussed

there will always be numerous conversations going on, just ask something

**patfla** · Jun 16, 2010, 01:01 PM

Re: Getting started with Kubuntu development.

hi claydoh

from this page

http://dev.nepomuk.semanticdesktop.org/

I found channel

#semdesk

(on freenode).

There seem to be 2 people other than myself on the channel. Just posted the same message there about nepomuk being broken.

I'm also doing

svn up nepomuk

every 5 or 10 minutes to see if new code appears.

How would I temporarily stub out the following dependency?

Re: Getting started with Kubuntu development.

I would update the "shared-desktop-ontologies"

Sources > sourceforge - OSCAF development space

Debianized > Package: shared-desktop-ontologies (0.5-1).

Hmm - what version of the Kubuntu are you using ?
The Maverick has > [ubuntu/maverick] shared-desktop-ontologies 0.5-1 (Accepted):

...
/usr/share/ontology/nepomuk/nuao.trig
...

**patfla** · Jun 17, 2010, 01:20 AM

Re: Getting started with Kubuntu development.

thanx. yes, I found that (shared-desktop-ontologies) and fixed it.

And with fixing what seemed a very long list of problems, I got it all working.

As in here:

http://techbase.kde.org/Getting_Started/Build/KDE4

Hooray.

Now I've gotten so lost in this whole process that I have to take a little time out and remember again why I did this.
