This page will automatically determine your operating system type and choose a suitable version for you. In the Linux system, before installing the downloaded program, remember to modify the file permissions, enter the directory of the file in the command line, and execute the following command (for example, I downloaded the file named Qt-unified-linux-x86-online.run):

You can modify the file properties to an executable file, and then execute the following command:

./qt-unified-linux-x86-online.run

Now QT's development package is getting bigger, the newest edition is already on G, sometimes we want to carry an offline installation package to use also appear to be very troublesome. At this time, we can choose to carry a relatively small QT creator installation package (100M or so), before the installation Update system library files (200M or so), so relatively direct carrying offline installation package more convenient. It should be noted here that this installation can only be installed to the QT4 version, if you need to install QT5, please do not use this method. specifically as follows: in the official download address select the required QT Creator version, I choose here is the 32-bit qt-creator-opensource-linux-x86-3.5.0

Update the Linux system's library files. The system version I use is as follows

Execute the following two instructions in the terminal command line, and note that the order of execution is not reversed:

sudo apt-get update

sudo apt-get install g++ gdb make CMake qt4-qmlviewer qt4-doc qt4-dev-tools build-essential LIBGL1 -mesa-dev

Send the created link to the desktop, and you can double-click it to open it later.

Mode 3: Installation via official offline installation package

Select the version you want at the official download site, and then download it. The official release of the compiled version, seemingly support 32-bit system version of the highest only 5.1.1.
Give the downloaded file permissions (my filename is Qt-linux-opensource-5.1.1-x86-offline.run) as follows:

chmod +x qt-linux-opensource-5.1.1-x86-offline.run
./qt-linux-opensource-5.1.1-x86-offline.run

In this way, you can start the installation.
