TX1入门教程软件篇-安装Qt

说明：

• 介绍如何在TX1上安装Qt

步骤：

• 下载qt：
• 地址：安装包qt-everywhere-opensource-src-5.5.1
• 解压后,修改文件qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf
• 修改如下：

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

MAKEFILE_GENERATOR      = UNIX  
CONFIG                 += incremental  
QMAKE_INCREMENTAL_STYLE = sublib

QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a  
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a

include(../common/linux.conf)  
include(../common/gcc-base-unix.conf)  
include(../common/g++-unix.conf)

# modifications to g++.conf
QMAKE_CC                = gcc  
QMAKE_CXX               = g++  
QMAKE_LINK              = g++  
QMAKE_LINK_SHLIB        = g++

# modifications to linux.conf
QMAKE_AR                = ar cqs  
QMAKE_OBJCOPY           = objcopy  
QMAKE_NM                = nm -P  
QMAKE_STRIP             = strip  
load(qt_config)  

• 修改qt.pro,去掉文件最后部分的一些不想编译的模块,比如:

addModule(qtbase)  
addModule(qtandroidextras, qtbase)  
addModule(qtmacextras, qtbase)  
addModule(qtx11extras, qtbase)  
addModule(qtsvg, qtbase)  
addModule(qtxmlpatterns, qtbase)  
addModule(qtdeclarative, qtbase, qtsvg qtxmlpatterns)  
addModule(qtquickcontrols, qtdeclarative, qtgraphicaleffects)  
addModule(qtmultimedia, qtbase, qtdeclarative)  
addModule(qtwinextras, qtbase, qtdeclarative qtmultimedia)  
addModule(qtactiveqt, qtbase)  
addModule(qtsystems, qtbase, qtdeclarative)  
addModule(qtlocation, qtbase, qtdeclarative qtquickcontrols qtsystems)  
addModule(qtsensors, qtbase, qtdeclarative)  
#addModule(qtconnectivity, qtbase $$ANDROID_EXTRAS, qtdeclarative)
addModule(qtfeedback, qtdeclarative, qtmultimedia)  
addModule(qtpim, qtdeclarative)  
addModule(qtwebsockets, qtbase, qtdeclarative)  
addModule(qtwebchannel, qtbase, qtdeclarative qtwebsockets)  
addModule(qtwebkit, qtbase, qtdeclarative qtlocation qtmultimedia qtsensors qtwebchannel qtxmlpatterns, WebKit.pro)  
addModule(qttools, qtbase, qtdeclarative qtactiveqt qtwebkit)  
addModule(qtwebkit-examples, qtwebkit qttools)  
addModule(qtimageformats, qtbase)  
#addModule(qt3d, qtdeclarative qtimageformats)
#addModule(qtcanvas3d, qtdeclarative)
addModule(qtgraphicaleffects, qtdeclarative)  
addModule(qtscript, qtbase, qttools)  
addModule(qtquick1, qtscript, qtsvg qtxmlpatterns qtwebkit)  
addModule(qtdocgallery, qtdeclarative)  
#addModule(qtwayland, qtbase, qtdeclarative)
addModule(qtserialport, qtbase)  
addModule(qtenginio, qtdeclarative)  
addModule(qtwebengine, qtquickcontrols qtwebchannel, qtwebkit qtlocation)  
addModule(qttranslations, qttools)  
addModule(qtdoc, qtdeclarative)  
addModule(qtqa, qtbase)  

• 到这里,qt里面需要修改的就完成了,但还需要对系统环境做些处理,让其满足qt的编译.
• 修改.bashrc,添加:

export SYSROOT  
export PKG_CONFIG_SYSROOT_DIR=/  
export PKG_CONFIG_LIBDIR=$SYSROOT/usr/lib/arm-linux-gnueabihf/pkgconfig:$SYSROOT/usr/share/pkgconfig:$SYSROOT/usr/lib/pkgconfig  
export PKG_CONFIG_PATH=$SYSROOT/usr/lib/arm-linux-gnueabihf/pkgconfig:$SYSROOT/usr/share/pkgconfig:$SYSROOT/usr/lib/pkgconfig  

• 执行source ~/.bashrc让其生效.
• 执行下面的命令，安装对xcb的依赖:

sudo apt-get install libxcb1 libxcb1-dev libx11-xcb1 libx11-xcb-dev libxcb-keysyms1 libxcb-keysyms1-dev libxcb-image0 libxcb-image0-dev libxcb-shm0 libxcb-shm0-dev libxcb-icccm4 libxcb-icccm4-dev libxcb-sync1 libxcb-sync-dev libxcb-xfixes0-dev libxrender-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0 libxcb-render-util0-dev libxcb-glx0-dev 

• 开始编译qt：

ubuntu@tegra-ubuntu:~/qt-everywhere-opensource-src-5.5.1$ mkdir build  
ubuntu@tegra-ubuntu:~/qt-everywhere-opensource-src-5.5.1$ cd build/  
ubuntu@tegra-ubuntu:~/qt-everywhere-opensource-src-5.5.1/build$ ls  
ubuntu@tegra-ubuntu:~/qt-everywhere-opensource-src-5.5.1/build$ sudo mkdir /opt/qt; ../configure -verbose -release -opensource -xplatform linux-arm-gnueabi-g++ -prefix /opt/qt -no-c++11 -qt-zlib -qt-xcb  
[sudo] password for ubuntu: 
+ cd qtbase
+ /home/ubuntu/qt-everywhere-opensource-src-5.5.1/qtbase/configure -top-level -verbose -release -opensource -xplatform linux-arm-gnueabi-g++ -prefix /opt/qt -no-c++11 -qt-zlib -qt-xcb

• 继续编译：

nmake -j4
sudo make install

• 最后在~/.bashrc添加:

export PATH=/opt/qt/bin:$PATH  
export LD_LIBRARY_PATH=/opt/qt/lib:$LD_LIBRARY_PATH  

• 更新环境：

source ~/.bashrc

• 检查是否成功：

qmake -version
