Qt installation in Linux

**lindalin** · 10th October 2010, 18:19

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.

Open a console window and type:
qtcreator
Followed by an enter.

Post the results here please.

Thank you ,tbscope. I searched my Red Hat Enterprise Linux 3.0 but found no 'console' ,so I tried 'New Terminal', after I typed the directory where I installed my Qt :cd /opt/qtsdk-2010.05/bin,and typed qtcreator followed by an enter,
it appears as :
bash: qtcreator: command not found
then I tried ./qtcreator,it appears as:
./qtcreator: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

what should I do now?

Hi, RedHat EL 3 ist pretty old. You probably have libstdc++.so.5 (in /usr/lib/). I'm not sure if it is possible to install the newer version in parallel (and it would possibly require a newer compiler, also not sure about that). You could try to compile the creator yourself (using your libstdc++.so version 5), but the easiest way to use the creator would be to update your linux.
