My presentation about getting started in development for Nemo Mobile and Mer from Devaamo Hackday 2012-09-8.

1. Getting Started in Hacking
Nemo Mobile and Mer
8.9.2012 Devaamo Hackday
Vesa-Matti Hartikainen
IRC: veskuh @ freenode / #nemomobile
Twitter: @veskuh

2. Trying it out
● Nemo Mobile images available for N900,
N9/N950 and x86
● https://wiki.merproject.org/wiki/Nemo/Installing

3. Development Tools
● Mer Platform SDK contains the recommended
toolset
– https://wiki.merproject.org/wiki/Platform_SDK
– Command line based toolset

4. App development
● Qt, Qt Quick, Meego Qt Componets, and Qt Mobility are good for
app developement.
● QtSDK's Harmattan (N9) target
– A bit limited, but mostly OK when developing new Qt/QML/Qt Mobility
based apps or porting apps from N9
– Easy to setup and supports also WIN & Mac
– https://wiki.merproject.org/wiki/Nemo/GettingStartedUsingQtSDK
● Developing apps in desktop
– Install Nemo's version of Qt Components to your linux desktop and use
normal Qt developement tools

7. Meego Qt Components in
N9 and in Nemo

8. New App Development
● Develop an app using any of the tools
● Make sure it works on x86 and ARM (test on
device)
● Create packaging for it in OBS
– Currently MeeGo Community OBS is used for Nemo
apps, this is likely to change in near term
● You can release app either via Apps For Meego
-repository or if it is good it may be included in
Nemo images as preloaded app.

9. Fixing Bugs in Nemo
● Register and grab a bug from bugs.nemomobile.org
● Find sources for the componet, typically from
github.com/nemomobile
● Find and fix the issue
● Pull request to upstream
● Mark the bug fixed
● Ask if somebody in #nemomobile could do a new release of the
component or if there is no active maintainer offer to do release
yourself
● https://wiki.merproject.org/wiki/Nemo/GettingStartedInFixingBugs

11. Contributing to Mer
● Read contribution guidelines first:
