Problem with QT 4 installation

Paulsrud · 08-11-2006, 03:49 AM

I use Ubuntu dapper, and I need QT 4 in order to install another application I want. I tried

Code:

qmake -v

which returned nothing. So I downloaded qt-x11-opensource-src-4.1.4 from their website. unpacked and did the usual

Code:

./configure
make
make install

that took alot of time. and now for the problems.
I tried

Code:

qmake -v

,
and tried to install the other app with qmake, but It doesn't recognize the qmake command.
Install says I need to extend environment variables.
So, I added

Code:

PATH=/usr/local/Trolltech/Qt-4.1.4/bin:$PATH
            export PATH

To /etc/.profile.
And tried again.
But no luck there either. Now I don't know what to do really.
I have also tried to apt-get it instead but couldn't find it., and searched for a answers
Help please.

The correct file is /etc/profile (without the dot). For testing purposes you can also execute the named commands on the console (in which case they only effect the console they were executed in).

Also, what do you mean by qmake -v not returning anything and your app not recognizing qmake?

Please post the exact commands you used and the ouput you get.

Sorry It was infact /etc/profile without dot i used, I put the PATH line in there as root. but I don't if it did it.
With that done, trying to install a app as it says i should with qmake, or just typing qmake it looks like this.

Code:

qmake
bash: qmake: command not found

Have you checked that /usr/local/Trolltech/Qt-4.1.4/bin actually exists?
Also try find /usr/local -name qmake; if that turns up another directory, put that one into /etc/profile instead of the above.

If the find command doesn't - well - find anything, qt isn't installed properly. At least, not under /usr/local.
In that case, I'd suggest installing QT via Ubuntu's package manager. You have to activate the universe repository; the package you need is libqt4-dev.

Usr/local/Trolltech/Qt-4.1.4/bin exist, but does not contain any file named qmake. Which it should, right? find /usr/local -name qmake didn't get any results.
Can i just try to reinstall it using synaptic, do i need to delete previous installation?

Well, technically you don't have to delete the previous installation, but for the sake of keeping the system clean (and not wasting disk space) I'd remove /usr/local/Trolltech as well as the entry in /etc/profile.

Thank you very much. Now it works.
