Qt5.5.1 transplantation (1): compile Qt source code

One: Get the Qt source code

Download link: http://download.qt.io/new_archive/qt/5.5/5.5.1/single/

Two: configure compilation options

1: Create the compiled output file "arm-qt" with any name, which is used to specify the address of the subsequent compilation output

2: Create a compilation script

#!/bin/sh
./configure \
     -prefix /home/jun/work/tool/qt5.5.1/qt-everywhere-opensource-src-5.5.1/arm-qt \
     -confirm-license \
     -opensource \
     -shared \
     -release \
     -make libs \
     -xplatform linux-arm-gnueabi-g++ \
     -optimized-qmake \
     -pch \
     -qt-sql-sqlite \
     -qt-libjpeg \
     -qt-libpng \
     -qt-zlib \
     -no-opengl \
     -no-sse2 \
     -no-openssl \
     -no-cups \
     -no-glib \
     -no-dbus \
     -no-xcb \
     -no-xcursor -no-xfixes -no-xrandr -no-xrender \
     -no-separate-debug-info \
     -no-fontconfig \
     -nomake examples -nomake tools -nomake tests -no-iconv \
     -tslib \
     -I/home/jun/work/tool/tslib/arm-tslib/include \
     -L/home/jun/work/tool/tslib/arm-tslib/lib
 exit

tslib installation document reference: https://blog.csdn.net/qq_34968572/article/details/90791464

3: Specify cross compilation tool and tslib

Modify the configuration file "qmake.conf" under the corresponding file according to the script content "-xplatform linux-arm-gnueabi-g++" created in the second section of this chapter

Three: Compile

1: Grant qutoconfiguer.sh script executable permissions and execute

chmod u+x autoconfigure.sh

./autoconfigure.sh

When the prompt as shown in the figure appears, the configuration is successful and you can start to compile

2: Compile: make (a bit long time)

3: Execute make install to install to the specified folder

After the installation is complete, no error is reported. /qmake -v to query the version number
