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 Starting dbus * system message bus already started; not starting. Starting UI in Xephyr Extended Input Devices not yet supported. Impelement it at line 625 in ../../../../hw/kdrive/src/kinput.c Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list! Could not init font path element /var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType, removing from list! X connection to :0.0 broken (explicit kill or server shutdown). xinit: connection to X server lost.
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.
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.
