Ubuntu
build-essential package

Qt IDE library required.

Asked by Rohith Kumar

I got the below error report while trying to build on Qt Creator 1.3.1, Based on Qt 4.6.2 (32 bit)... I think some libraries are missing. Can anyone help me to resolve this build error report. It would be grateful.

you do not have a C++ compiler installed. The C++ compiler that is shipped with ubuntu is g++.

install the build-essential package.

The same way you install any other software in ubuntu, through the repositories.
http://www.psychocats.net/ubuntu/installingsoftware

If you get stuck trying to use the graphical interface to install the package, you can use the following commands to do it.

First press Ctrl+Alt+T to bring up a terminal, then cut and paste this command

sudo apt-get install build-essential

now you will be prompted for your password. This will not print anything when you type, but your password will be accepted when you press enter.
