Hi,I need to install a version of Qt in my Red Hat Enterprise Linux 3.0, so I picked the LGPL and then the Qt SDK for Linux/X11 32-bit ,downloaded the "qt-sdk-linux-x86-opensource-2010.05.1.bin" from the official website. Then I double clicked the "qt-sdk-linux-x86-opensource-2010.05.1.bin" and installed it, but when I double clicked the "Qtcreator"icon created after the installation, the software never runs. Could someone tell me on which step had I made a mistake? Thank you very much.
