QT ARM交叉编译

arm平台：BeagleBone Black

编译平台：ubuntu16.04

交叉编译工具：arm-linux-gnueabihf

qt源码：qt-everywhere-opensource-src-5.8.0.tar.gz

设置arm-linux-gnueabihf路径

~$ vim ~/.bashrc

向文件中加入如下一行

export PATH=$PATH:~/gcc-linaro-4.9-arm-linux-gnueabihf/bin

保存并退出文件，刷新

~$ source ~/.bashrc

配置并编译qt

修改qt支持arm-linux-gnueabihf交叉编译工具

~$ tar -xzf qt-everywhere-opensource-src-5.8.0.tar.gz ~$ cd qt-everywhere-opensource-src-5.8.0/qtbase/mkspecs ~/qt-everywhere-opensource-src-5.8.0/qtbase/mkspecs$ cp -r linux-arm-gnueabi-g++/ linux-arm-gnueabihf-g++ ~/qt-everywhere-opensource-src-5.8.0/qtbase/mkspecs/linux-arm-gnueabihf-g++$ vim qmake.conf

把文件中的arm-linux-gnueabi替换为arm-linux-gnueabihf，如下内容

# # qmake configuration for building with arm-linux-gnueabihf-g++ # MAKEFILE_GENERATOR = UNIX CONFIG += incremental QMAKE_INCREMENTAL_STYLE = sublib include(../common/linux.conf) include(../common/gcc-base-unix.conf) include(../common/g++-unix.conf) # modifications to g++.conf QMAKE_CC = arm-linux-gnueabihf-gcc QMAKE_CXX = arm-linux-gnueabihf-g++ QMAKE_LINK = arm-linux-gnueabihf-g++ QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++ # modifications to linux.conf QMAKE_AR = arm-linux-gnueabihf-ar cqs QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy QMAKE_NM = arm-linux-gnueabihf-nm -P QMAKE_STRIP = arm-linux-gnueabihf-strip load(qt_config)

配置qt

~/qt-everywhere-opensource-src-5.8.0/qtbase/mkspecs/linux-arm-gnueabihf-g++$ cd ~/qt-everywhere-opensource-src-5.8.0 ~/qt-everywhere-opensource-src-5.8.0$ ./configure -prefix $PWD/qtbase -opensource -xplatform linux-arm-gnueabihf-g++ -no-opengl -nomake examples

编译qt

~/qt-everywhere-opensource-src-5.8.0$ make -j4 编译完成后在Qt Creator内设置qmake路径，就可以使用了
