How to get qt to work?

[25an]

Hi i have installed qt4 but i cant get it to work.
When i run qmake on a project i get the makefile but then when i run make
it dont find the qt rellated classes.
I understand that it has something to do with the environment variables for qt but I dont know where to
put them.
I found on qt's homepage that I should put some environment variables in the .profile but i cant find it?
Is this the same as the .bashrc file in my home dir?
I found a profile file in /etc/ but it was't hidden?
But I did find a .profile file in the /root dir and it look some thing like the /etc/profile file.

Do you have any ideas what i should do?

I created a .profile file and added the environment variables I run it with bash and the echo $PATH
the dir was added to the environment variable PATH but i still cant get it to work after I have run qmake and then make I get error messages like
finddialog.cpp:53: error: ‘QString’ was not declared in this scope

Your ".profile" file is actually called ".bash_profile" and it is in your home directory. For the rest, look at this thread. ShOcKwAvE explains what you have to do.

Thanks for your replay i followed the thread but now I get

..
...
QtCore_debug -lpthread
/usr/bin/ld: cannot find -lQtGui_debug
collect2: ld returned 1 exit status
make: *** [find] Error 1

Do you have any idea what this means?

It means that the linker couldn't find the library libQtGui_debug. You should be able to use the "locate" or "find" commands to find it.

Thanks I managed to get it to work!
I did as it was posted in the thread above.
But I will write it down any way, first of all I was not interested in having Qt3 and Qt4 so I removed Qt3 you dont have to do this but you have to create a alias since /usr/bin/qmake points to /etc/alternatives/qmake and that in turn points to /usr/bin/qmake-qt3. Create the alias by run following

sudo ln -sf /usr/bin/qmake-qt4 /usr/bin/qmake

But if you like to be able to run qmake-qt3 still do following

sudo ln -sf /usr/bin/qmake-qt4 /usr/bin/qt4make

move to /usr/bin and run ls -l q* you should get something like this
