1. Get

From me to the disk download: qt-creator-opensource-linux-x86_64-3.5.1.run

The following are open Source: http://download.qt.io/official_releases/qtcreator/

http://download.qt.io/official_releases/qt/

2. Qt Creator Installation

2.1 Put the downloaded file (qt-creator-opensource-linux-x86_64-3.5.1.run) into the Cntos user directory where I placed the

Place for:/home/tian/software

2.2 Modify file permissions so that they have Execute permissions

chmod u+x Qt-creator-opensource-linux-x86_64-3.5.1.run

2.3 Installation

./Qt-creator-opensource-linux-x86_64-3.5.1.run

during its period, the Setup Wizard will ask for the installation path, which I have installed by default in the/home/tian/qtcreator-3.5.1 directory.

After the installation is complete, there is a Qt Creator entry in the application---programming menu. Click will pop up QT Creator

interface, or you can right-click on "Add this launcher to the desktop" and create a shortcut on the desktop.

3. QT SDK Installation

Although the QT Creator is installed, it is not possible to create and compile the project. You will also need to install the QT SDK.

3.1 Put the downloaded file (qt-everywhere-opensource-src-4.8.7.tar.gz) into the Cntos user directory where I placed the

Place for:/home/tian/software

3.2 Decompression

Tar zxvf qt-everywhere-opensource-src-4.8.7.tar.gz

3.3 Modifying environment variables

Modify the ~/.BASHRC file

Vim ~/.BASHRC

After the file, add the following:

< Span style= "FONT-SIZE:14PX; Font-family:courier New; " > Qtdir=/home/tian/software/qt-everywhere-opensource-src-4.8.7

Path= $QTDIR/bin: $PATH

Manpath= $QTDIR/man: $MANPATH

Ld_library_path= $QTDIR/lib: $LD _library_path

Export Qtdir PATH MANPATH Ld_library_path

The function of this script is to add the Bin,bin,man path in the directory we just unzipped to the environment variable.

3.4 Configuration

Cd/home/tian/software/qt-everywhere-opensource-src-4.8.7

./configure

There is a hint that GCC is not installed in this procedure and the GCC is installed below

Yum Install gcc gcc-c++

After the installation is successful, the following error occurs when you re-proceed to the above step:

　　Basic XLIB functionality Test failed!
　　You might need to modify the Include and library search paths by editing
　　Qmake_incdir_x11 and qmake_libdir_x11 in/....

Workaround:

　　Yum Install Libx11-devel,libxext-devel,libxtst-devel

Then re-perform the above steps without error

3.5 compiling

Gmake

This is a long process (it may take several hours), please wait patiently

3.6 Installation

This step may take about 15 minutes.
