Qt source code compilation

Qt source code compilation

• Download qt-everywhere-src-5.15.0.tar.xz from http://download.qt.io/archive/qt/5.15/5.15.0/single/ to Linux and unzip it;
  

• Go to the unzip directory and create a new compiled script make.sh

  # cd qt-everywhere-src-5.15.0
  # touch make.sh
  # chmod 777 make.sh

  

• Modify the qmake. conf

# vi qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

#
# qmake configuration for building with arm-linux-gnueabihf-g++
#

Start cross-compiling:

# ./make.sh

After waiting for some time, the compilation is complete:

Set the qmake environment variable:

# vi ~/.bashrc
# export PATH=/home/ronnie/work/ssd201/qt/qt-everywhere-src-5.15.0/install/bin:$PATH

# source ~/.bashrc
# which qmake
