I am new to ubuntu and using 12.04 LTS. I tried to install Qt5.1.1 without software manager. I downloaded the qt-linux-opensource-5.1.1-x86-offline.run file and ran it.
It ran smoothly and got a installed in a folder. However when I try to navigate to the
/home/Qt5.1.1/Tools/QtCreator/bin and execute the qtcreator executable from the terminal I get the error
Segmentation fault (core dumped)..it will be really helpful if some one suggested how to correctly install Qt5.1.1 and get rid of this error.
