Udooz!

This is part 2 of Event Watch: Moblin - Intel's Mobile Flavour Part 3.

After getting all the components, I could start Xephyr on the MIC device target terminal window. But, it did not keep me smile. The Xephyr window was broken immediately and I got the following error

(T: HelloMoblinApp)root@sheik-laptop:/#  ...
Xlib: connection to ":0.0" refused by server

It was my mistake that I forgot to install LibOSSO library. Then I installed it on the target terminal.

(T: HelloMoblinApp)root@sheik-laptop:/# apt-get install libosso-dev

After that I started Xephyr, this time it throws

(T: HelloMoblinApp)root@sheik-laptop:/# ume-xephyr-start
Setting screen resolution to 1024x600
DISPLAY already set to  :0.0

Then I've gone thorugh some mail-list and I found a workaround at http://www.moblin.org/archives/html/dev/2008-04/msg00101.html. It said that use

# pkill gconfd

It kills parent's gconfd and uses target environment's gconfd. After that Xephyr started successfully but it throws same warning message, just skip that.

After that I was trying to compile and execute the given hello-world-1.-c at Moblin.org site. However, I am not able to compile, it says

(T: HelloMoblinApp)root@sheik-laptop:/usr/src/hello# gcc -o hello-world-1 hello-world-1.c `pkg-config --cflags --libs gtk+-2.0`
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
-su: gcc: command not found

Ha ha interesting, I was not in the situation whether gtk+-2.0 is already there in my Ubuntu or not. I just given

(T: HelloMoblinApp)root@sheik-laptop:/# sudo apt-get install libgtk2.0-dev

After that you have to install gcc on the target terminal

(T: HelloMoblinApp)root@sheik-laptop:/# sudo apt-get install gcc

After that I have successfully executed the hello world app.

Thank God.

One good thing is that the packages "gcc" and "libgtk2.0-dev" are got from host app only. It is nice thing about Moblin.

Let us see with more code on Moblin.
