Qt Installation failing

[kmorgado]

Hey everyone, i'm trying to install Qt 4 on Ubuntu 10.04 and the make command keeps crashing on me.

Here is the tail end of my output:

cd src/network/ && make -f Makefile

Is there some type of dependency that im missing? If someone could help me out I would appreciate it!

1. I don't think that it is a good idea to build QtNetwork library separately. Just go to /opt/Qt4/qt/, do configure there and then run make from there.
2. How did you configure qt?

You have got another option also, if you are not a hardcore linux fan. Donot install from terminal window, Instead try easier option. Goto Applications->Ubuntu software center. There select developer tools & then just enter qt4 in search box. it will automatically list out all qt4 package available. My advice is go for qt creator, it has everything in it. I am sure u will love it.

Make sure you have installed all the requirements listed here: http://doc.trolltech.com/4.6/requirements-x11.html. Further, if you don't want to do any fancy stuff with the source code, simply use the standard installer provided at the download page at qt.nokia.com: No long compilation time, tested libraries...

Found this post (http://www.qtcentre.org/threads/29410-Mysterious-QSslSocket-error-causes-installation-to-fail-on-Ubuntu-64-bit.) with a forum search. Looks like the same problem that you're having. The solution is in the thread which is to do as Lykurg says.
