sudo apt-get install libxkbcommon-x11-dev3. Install qt
3.1 Decompress the downloaded qt source code and enter the decompressed directory
3.2 The decompression command has two lines, because there are two layers of compression, or GUI operation, right click - extract here
xz -d qt-everywhere-opensource-src-5.9.7.tar.xz
tar -xvf qt-everywhere-opensource-src-5.9.7.tar3.3 After decompression, enter the directory and execute the script
cd qt-everywhere-opensource-src-5.9.7
./configureThere may be an error report make: ***[module-qtbase-make_first] Error 2
Solution: Execute make clean
and then clear the QT source code files, clear the temporary files generated by compiling QT, restart, and release the Qt source code again
3.4 Select version (o) and accept agreement (y)
3.5 Compile, if it is slow, use multi-threading, multi-threading will be very stuck and may cause errors, it is recommended to hang up and make
Compile 3 ~ 12 hours
make
或者
make -j2 Error: makefile:638:recip for target "xxxxxxx" failed
Solution: Execute make clean
to clear the temporary files generated during compilation, create a temporary folder in the source code directory, compile again in the temporary folder, modify and place the directory after compiling报错： make:***[Makefile:337:module-qtdeclarative-make_first] Error 3
Solution: python may be replaced by python2 or python3, resulting in no mapping.
ls /usr/bin/python* Check if there is python or not,
create a soft link: ln -s /usr/bin/python3 /usr/bin/python
3.6 Installation The default installation directory is under /usr/local/
sudo make install 3.7 Configure environment variables and open the configuration file
sudo vim /etc/profile3.8 Write environment variables and add the following content to the end of the configuration file
(Note that the installation path fills in the actual installation path to avoid mistakes)
export QTDIR = /usr/local/Qt-5.7.1
export PATH = $QTDIR/bin:$PATH
export MANPATH = $QTDIR/man:$MANPATH
export LD_LIBRARY_PATH = $QTDIR/lib:$LD_LIBRARY_PATH3.9 Enabling environment variables to take effect
source /etc/profile3.10 Verify whether it is in effect, normally there will be version information output
qmake -v4 Install QtCreator
4.1 Unzip qt-creator-opensource-src-4.7.1.tar.gz to the current directory
tar -zxvf qt-creator-opensource-src-4.7.1.tar.gz4.2 Enter the decompressed directory and create a temporary directory, enter the temporary directory
cd qt-creator-opensource-src-4.7.1
mkdir build
cd build4.3 Start compiling, if compiling is slow, use multithreading, make - j2
It takes a long time to compile, it is recommended to hang up make
qmake -r
make 4.4 Installation
sudo make install4.5 After installation, you can open QtCreator
May report an error: Cannot find.... makefile recipe....
Solution: Delete the makefile in the build directory.
Under the QtCreator build settings, set the build environment and
clear the system environment variables✔
QtCreator - Project - Build Settings - Build Environment - Details - Clear System Environment Variables
After adding the project, an error may be reported when starting qt-creator: Failed to overwrite xxxx file
Solution: Give permission when running QtCreator
Start qt-creator using command line
sudo ./qtcreatorqtcreator may be in (in /usr/bin or /bin/ directory),
Or use whereis qtcreator to find the path
ps: I installed two qtcreators here, and the Chinese garbled characters installed with the source code, so I installed another one with the command line
