系统：14.04及16.04均测试 64位
工具：gcc-linaro-4.9-20190425 qt-creator-opensource-linux-x86_64-3.5.1.run
处理器：AM335X
原开发板供应商：天嵌
1、14.04系统执行环境：
#!/bin/sh
add-apt-repository "deb http://archive.canonical.com/ lucid partner"
apt-get update
echo y|apt-get install gnupg flex bison gperf zip curl zlib1g-dev libc6-dev lib32ncurses5-dev lib32z1 lib32ncurses5 lib32bz2-1.0 x11proto-core-dev libx11-dev lib32readline-gplv2-dev lib32z1-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils genext2fs libswitch-perl
ln -s /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-gnu/libX11.so
echo y|apt-get install gcc-4.4 g++-4.4 g++-4.4-multilib
mv -f /usr/bin/gcc /usr/bin/bak_gcc
mv -f /usr/bin/g++ /usr/bin/bak_g++
ln -s /usr/bin/gcc-4.4 /usr/bin/gcc
ln -s /usr/bin/g++-4.4 /usr/bin/g++
cp /usr/include/x86_64-linux-gnu/zconf.h /usr/include/zconf.h
2、更新gcc为4.9版本
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get install software-properties-common
sudo apt-get upgrade
sudo apt-get install gcc-4.9 g++-4.9
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 49 \--slave /usr/bin/g++ g++ /usr/bin/g++-4.9 \--slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-4.9 \--slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-4.9 \--slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-4.9
3、交叉编译工具链执行文件为gcc-linaro-4.9-20190425.tar
#tar jxvf gcc-linaro-4.9-20190425.tar.bz2 -C /
#echo PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/EmbedSky/linaro-4.9/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin:/opt/EmbedSky/linaro-4.9/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/sysroot/usr/bin">> /etc/environment
#source /etc/environment
#arm-linux-gnueabihf-gcc -v
4、更新qt5安装需要的插件 https://wiki.qt.io/Building_Qt_5_from_Git
sudo apt-get build-dep qt5-default
sudo apt-get build-dep qtbase-opensource-src
sudo apt-get install libxcb-xinerama0-dev
Build essentials：sudo apt-get install build-essential perl python git
Libxcb：sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
Qt WebKit：
sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby
Qt WebEngine（14.04）：
sudo apt-get install libbz2-dev libgcrypt11-dev libdrm-dev libcups2-dev libatkmm-1.6-dev
Other
sudo apt-get install libssl-dev libxcursor-dev libxcomposite-dev libxdamage-dev libxrandr-dev libdbus-1-dev libfontconfig1-dev libcap-dev libxtst-dev libpulse-dev libudev-dev libpci-dev libnss3-dev libasound2-dev libxss-dev libegl1-mesa-dev gperf bison
Qt Multimedia：
sudo apt-get install libasound2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
QDoc Documentation Generator Tool：
sudo apt install libclang-6.0-dev llvm-6.0
编译过程中，libclang 和llvm无法安装，使用aptitude更新 ：
sudo apt-get install aptitude 再安装 sudo aptitude install libclang-dev , sudo aptitude install llvm
5、安装 qt-creator-opensource-linux-x86_64-3.5.1.run
6、下载qt5.5.0的源码，编译pc版本
./configure --prefix=/home/ran/build/pc5.5.0
make
Make install
结束时报qtdoc的编译没有成功，忽略
7、编译arm版本qt5.5.0
gedit qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf
修改 arm-linux-gnueabi 为 arm-linux-gnueabihf
在 QMAKE_INCREMENTAL_STYLE = sublib之后增加：
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a
QMAKE_INCDIR += /opt/EmbedSky/linaro-4.9/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/sysroot/include
QMAKE_LIBDIR += /opt/EmbedSky/linaro-4.9/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/sysroot/lib
修改解压目录下的qt.pro文件
gedit qt.pro & 找到
addModule(qt3d, qtdeclarative qtimageformats)
addModule(qtcanvas3d, qtdeclarative)
并添加#注释掉，再执行配置
echo yes|./configure --prefix=/home/ran/build/arm5.5.0/ -opensource -release -xplatform linux-arm-gnueabi-g++ -no-opengl -no-iconv -no-sse2 -no-cups -no-glib
make
Make install
结束时报qtdoc的编译没有成功，忽略。将编译的库文件等拷贝到目标板文件系统目录的相应位置即可。
8、通过超级终端在开发板系统中添加环境变量，可以在开发板文件系统的/etc/profile文件里添加，也可以直接添加。
export TSLIB_TSDEVICE=/dev/input/touchscreen0
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
9、配置qtcreator 及 gdb远程调试
交叉编译工具4.9中包含arm版本的gdbserver 和 gdb，可以直接配置。将gdbserver 拷贝到目标板的bin目录
至此，完成配置和远程调试。
