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.

Hi again,
I finally came to know that I am not supposed to paste the 'PATH=/usr/local...' to my projects.pro file but should be adding it to .profile found in 'home' directory.Now,I am a newbie to Linux so,I guess home directory for root is '/root'(I am logging in as root).
I tried 'ls -a' inside root directory but didn't find any .profile...so I followed suggestions from the internet and created one.
I added the PATH=/usr/... to my .profile and saved it in root directory.
(I haven't yet configured 'qvfb' cause I haven't got a clear answer on my query about that till now.)
So,now,when I try to run a demo 'textedit',I get the following errors------------------

[root@localhost browser]# cd /usr/local/Trolltech/QtEmbedded-4.5.0-tp1/demos/textedit
[root@localhost textedit]# qmake textedit.pro

Seems like 'QTextDocumentWriter' a Qt embedded class is not found.I can't figure out what I have been doing wrong or if I missed some step in between(I did follow the installation guide).
Would appreciate some help in resolving this issue.
Thanks in advance.

Hi again,
ok,it's still not working but, I believe I am getting closer to solving the mystery.A member from the qt-embedded mailing list pointed out that it seemed like I was trying to compile with the wrong Qt version ,which became so obvious once I had a good look at the errors(I think from next time I will try to work out things a bit, before rushing here for help,saves a lot of embarassment ).
Now,the question is, how do I change the settings so as to use 'qmake' associated with with Qt emb. 4.5....I did paste the 'PATH=/usr/local...export PATH' in .profile in my root directory.(please see the details in the second post)
Hope someone will be able to help.
Thanks.
