[balajir]

Installed gstreamer-devel and gstreamer plugin base-devel successfully..

Also now configured qt with phonon, gmake and gmake-install successfully..

also set environment variable by

PATH=/usr/local/Trolltech/Qt-4.5.2/bin:$PATH
export PATH

Now i dont know how to run sample phonon example in linux..?

I went to the example directory say "musicplayer" and tried these things

qmake -project
qmake
make
when i give make it is showing error

[root@localhost musicplayer]# ls

You should have NOT run "qmake -project". The example already had a properly working .pro file. Restore the original .pro file from the tarball and leave out the "qmake -project" step this time.

How to restore the original .pro file from the tarball?

Or you just add
Qt += phonon
in your .pro file.

How to run phonon on Qt examples?

run ??

If you want to add phonon module, just add above line.

[balajir]

Even basic examples are not running properly(not phonon)

.pro is already created in QT examples..

I just did

qmake application.pro
qmake
./application

But when i give ./application to run, it throws an error that

"Cannot connect to the X server"

Kindly help me..

Why 2 times, you are calling "qmake" ?
"qmake" never builds your project.
Would have called "make".
Please, refer QtAssistant, I think you require some basics.

[balajir]

Ya i know that..

I want you to see this once

http://linuxhelp.blogspot.com/2006/0...ojects-on.html

By doing qmake name.pro will create a platform specific Makefile.. This Make file is not in my directory.. Just cpp,.h and .pro files alone in directory so I gave qmake name.pro to create a Makefile..

Are you saying because of giving qmake i am getting the previous errors?

Thanks,

"Cannot connect to the X server"

This means you are not using qmake from Qt/X11 4.5.2 as you claim, but from Qt for Embedded Linux. What does "qmake -v" output?

Sorry I dont understand...

Kindly tell me clearly what i should do to solve the error and run a phonon example..

Also whats the exact problem..?

Please learn to use your computer first. Maybe then come back to programming.

I know to use my Computer.. I myself find a solution for my problem......

Anyways Thanks for your advice and help...

[balajir]

qmake -v output is


QMake version 2.01a
Using Qt version 4.5.2 in /usr/local/Trolltech/Qt-4.5.2/lib

Oops, I somehow misread "Cannot connect to the X server" as "Cannot connect to the QWS server". Ok, so do you have an X server running? Anyhow this problem is not related to Qt, it's related to your environment.
