Need help in installing Qt-embedded 4.5(on linux fedora 8)

[rishiraj]

Hi everyone,
I am trying to install Qt-embedded in my Linux Fedora 8 desktop PC(package name is "qt-embedded-linux-opensource-src-4.5.0-tp1.tar.gz")
I followed the steps in the installation doc...started with the configure script,then ran 'gmake' and finally 'gmake install'...it's not showing any errors so, I assume that till now things are ok. Now,as per the installation doc--
As I have a bash shell,I should add the following line-
PATH=/usr/local/Trolltech/QtEmbedded-4.5.0-tp1/bin:$PATH
export PATH to .profile

So,I added the above line in my 'projects.pro' file in the qt-embedded package I had downloaded.
************************************************** ****
Now,my questions are:
1)Do I have to paste the line (PATH=/usr....) at some specific point in the projects.pro file?
I just pasted it at the end of the file.More importantly,am I supposed to paste it in the projects.pro file or are they meaning some other .profile

2) After adding the above,what do I do ?
Do I run qmake,make again (cause I changed the .pro file) or, is this it?
(update)Did try running qmake,shows-
[root@localhost qt-embedded]# qmake projects.pro
/root/Desktop/qt-embedded/projects.pro:8: Parse Error ('export PATH')
Error processing project file: projects.pro


3)Do I have to configure Qt embedded/qvfb or can I do without that for now(Also,I have Qt/X11 installed in the same PC so,do I need to do anything at all for 'qvfb')
************************************************** ******
I tried running one of the demo examples 'browser' but, it's showing errors.

I need to know if I made some mistake in the installation or is it something else.
Thanks in advance for any help.
