Hello around

We are pretty thankfull about MeeGo, the Wiki and all the warm support we get. So we would like to give some lessons, we learned on the way, back to all of you.

The lesson today: What is the most efficient way to compile and debug with qt creator when you have external (core) libs.

There are basically 2 ways:

a) Use Qemu, install qt creator on the Image and get working in there.
b) Use a changeroot environment.

We found that:
Way a) is slow, unstable and cost a lot of nerve, developers and time...
Way b) is only possible when you do work for i86 (or use an arm computer as base)...

Both ways have an huge downside and we wondered, 'WTF' this can not be true.
But finally we got to Way c).

Way c) is: Use the kickstart to generate your own sysroot, of course you should add your needed core libs before. When you have generated the new sysroot.
1. add it to your madde
2. select in qtcreator (tools->configuration->qt4) the qmake from within the new sysroot (like described in SDK Setup Wikipage).

Guess what, that is it, it does simply work out of the box.


We agree, Way c) does have one downside: You need to generate your own sysroot, which you might not be able to.

And definitely nobody want to have an own sysroot for each application he work on. Also we want to provide broad compatibility between open source applications and hate the idea that every meego developer need to install an new sysroot starting to work on our codebase...

So our standpoint is, for now this is the only really working and bullet proof solution. But we think that every library + dev (better also dbg) package of the core compliance spec should be included in the default sysroot.

Doing it this way, you can work for arm and for i86. Debug and run just on device by using qt creator and forget about all this qemu, changeroot crap.

Just click, compile, run, debug and start working on the software, not the environment.

Thanks for reading and we hope this helps others to get started faster with meego development.

We plan to provide an 'simple to use and take care of everything script' which allows everyone (Linux User at least, sorry Windows Guys) to generate a own sysroots by just calling one command.

Hello ,

I hope it s the right forum to ask the question.

i installed the meego sdk MeeGo 1.2 Tablet UX Pre-Alpha Release.
the installation was done on ubuntu and windows 7.
I followed the procedure that is clear for the first step but clearly incomplete the setting up of the toolschain, and the setting up of meegotouchlib.

On ubuntu .
no major problem except that the run setting doesn't show up the meego target , same if i can test the ssh connection that work well.

I didnt see the straight deployment of the package like for maemo5 for instance when i click on run.

On Win7.
installation goes well.impossible to find an already dll about meegotouch,anyone know a w32 repos ?

The installation procedure for meego touch is quite complexe and not made for the masses.
