Select tar.xz

Unzip it after downloading in the opt folder

sudo tar -xvf qt-everywhere-src-5.14.2.tar.xz -C /opt/

After the decompression is complete, enter the folder and create auto.sh script file.

sudo vim auto.sh
sudo chmod 755 auto.sh

#! /bin/bash
./configure -prefix /opt/Qt/ \

qtlocation qtwebengine, if you do not specifically need these two modules, it is recommended not to compile These commands are described in the unzipped README After the execution, improve the system as prompted. Most of the errors are due to incomplete installation Carry out

sudo make -j4

Long time, 4-12 hours based on board function

FAQ: If you have already installed python3, but the Python interpreter is missing during the build process, you can create a symbolic link:

sudo ln -s /usr/bin/python3 /usr/bin/python

Execute after completion

sudo make install

This command installs the program in/opt/Qt/. Modify environment variables after successful installation:

sudo vim /etc/profile

export QTDIR=/opt/Qt
export PATH=$QTDIR/bin:$PATH
export MANPATH=$QTDIR/man:$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

source /etc/profile/

Compile and install qtcreator

To install qtcreator, you must first install Qt and compile qtcreator with Qt. If there is an error in compiling Qt, the compilation at this location will also error. If there are uncompiled modules or undependent modules when Qt is compiled, the qt compilation will not be affected, but the qtcreator will be affected. I tried adding -no-opengl, and there is no error in compiling qt. You can install it, but the qtcreator will fail.

Qtcreator should preferably correspond to the Qt version Qtcreator source code

Unzip after download is complete Here, the above tutorial is defaulted to after completion: Enter the decompression path and execute

qmaek -r

Wait for the MakeFile file to be generated after completion. Then execute

sudo make -j4

After the compilation is completed, execute

sudo make install

After execution, open the bin folder and there will be qtcreator and qtcreator.sh Execute./qtcreator.sh & This way qtcreator will run in the background. Finally, you can configure qtcreator. Tools - > Options - > Kits Kits Select gcc as the compilation toolchain corresponding to the board. Generally, qtcreator is equipped with the gcc tool version by default, and select the cross-compilation tool corresponding to uname -r. It is best to use the cross-compilation tool with the same version number in the SDK.
