# 移植QT5.9.1
移植完成tslib之后，就可以进行QT本体的移植了，目前最新版本为5.9.1.
注意QT本体编译时间较长，笔记本上会耗时2~3小时，我使用的32线程服务器的编译时间为9分钟左右。
## 下载QT5.9.1
~~~
wget http://download.qt.io/official_releases/qt/5.9/5.9.1/single/qt-everywhere-opensource-src-5.9.1.tar.xz
tar xf qt-everywhere-opensource-src-5.9.1.tar.xz #这里解压也需要30s左右，别以为死机了。。
cd qt-everywhere-opensource-src-5.9.1
./configure --help >help.txt #QT的配置较为复杂，进来先看看帮助文档，在本节最后附录里有翻译
~~~
一般来说，我们需要编译主机和目标板两个版本的qt：
主机版可以用于前期的gui的设计调试；目标板用于实际产品的验证。
## 编译X11版本
主机版一般是X11，配置如下：
cfg_X11.sh
~~~
#!/bin/bash
./configure -prefix /opt/qt-5.9.1-x11 -opensource -make tools
#安装位置，开源版本，编译qt工具（makeqpf,qtconfig）
make -j32
sudo make install
~~~
运行该脚本，首次配置用时1分钟左右。编译一次参考时间：
~~~
real 9m17.309s
user 206m59.052s
sys 17m30.300s
~~~
所以单核虚拟机编译需要三小时左右。
编译完成后install也需要1分钟左右。
安装完成后在/opt/qt-5.9.1-x11下可见安装的文件。
## 交叉编译arm版本
注意，在第二次编译前，先make clean下。如果编译时候仍有错误，可以重新解压编译。
交叉编译，需要配置 xplatform选项，比如要在arm-linux平台上移植Qt的话，就在配置项中加上 -xplatform linux-arm-gnueabi-g++ ，这个是平台名字，Qt5支持的交叉平台都可在源码顶层目录中的 /qtbase/mkspecs/ 下找到。
首先我们需要编辑qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf：
加上：（注意，和tslib类似，这里要加上其它什么支持的话，也是交叉编译的库的路径）
~~~
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a -lts
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a -lts
QMAKE_INCDIR += /opt/tslib/include /opt/sqlite3/include
QMAKE_LIBDIR += /opt/tslib/lib /opt/sqlite3/lib
~~~
把arm-linux-gnueabihf-gcc改成arm-linux-gnueabi-gcc等。
然后再编辑配置脚本cfg_arm.sh
~~~
#!/bin/sh
./configure -verbose \
-prefix /opt/qt5.9.1-arm \
-confirm-license \
-opensource \
-release \
-make libs \
-xplatform linux-arm-gnueabi-g++ \
-optimized-qmake \
-pch \
-sql-sqlite -sqlite \
-qt-libjpeg \
-qt-libpng \
-qt-zlib \
-tslib \
-no-opengl \
-no-sse2 \
-no-openssl \
-no-cups \
-no-glib \
-no-dbus \
-no-xcb \
-no-separate-debug-info \
-I/opt/tslib/include -L/opt/tslib/lib \
-make examples -make tools -nomake tests -no-iconv
~~~
~~~
make -j32
sudo make install
~~~
完成后，相关文件在/opt/qt5.9.1-arm下。
## 向开发板添加Qt库
首先将/opt/qt5.9.1-arm和/opt/tslib 复制到开发板的对应目录下
然后设置开发板 Qt 环境变量，vi /etc/bash.bashrc
添加下面内容：
~~~
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_CONFFILE=/opt/tslib/etc/ts.conf
export TSLIB_PLUGINDIR=/opt/tslib/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export LD_LIBRARY_PATH=/lib:/usr/lib:/opt/tslib/lib:/opt/qt5.9.1-arm/lib
export PATH=/bin:/sbin:/usr/bin/:/usr/sbin:/opt/tslib/bin
export QT_QPA_PLATFORM_PLUGIN_PATH=/opt/qt5.9.1-arm/plugins
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_QPA_FONTDIR=/opt/qt5.9.1-arm/lib/fonts
export QT_QPA_GENERIC_PLUGINS=tslib:$TSLIB_TSDEVICE
~~~
保存后生效上述内容：source /etc/bash.bashrc

## 附录：QT配置帮助文件 翻译
Usage: configure [options] [assignments]
在命令行使用VAR=value来配置变量。
每个大写的库名（用-list-libraries可以查看），支持这些后缀：
_INCDIR, _LIBDIR, _PREFIX (INCDIR=PREFIX/include, LIBDIR=PREFIX/lib),
_LIBS, and - on Windows and Darwin - _LIBS_DEBUG and _LIBS_RELEASE. E.g.,
ICU_PREFIX=/opt/icu42 ICU_LIBS="-licui18n -licuuc -licudata".
同时支持操作QMAKE_* 变量，来修改mkspec里指定的值，比如QMAKE_CXXFLAGS+=-g3.
**顶层安装路径：**
-prefix <dir> ...... 目标路径（在开发板上的绝对路径）
[如果使能了developer-build，就是/usr/local/Qt-$QT_VERSION, $PWD]
-extprefix <dir> ... 安装路径（在主机上的路径，比prefix更多一个前置路径），可不写
[SYSROOT/PREFIX]
-hostprefix [dir] .. The installation directory for build tools running on
the host machine. If [dir] is not given, the current
build directory will be used. [EXTPREFIX]
-external-hostbindir <path> ... Path to Qt tools built for this machine.
Use this when -platform does not match the current
system, i.e., to make a Canadian Cross Build.
**微调安装路径的分布**，注意除了-sysconfdir外的所有目录需要在-prefix/-hostprefix下。
（这里基本可以不配置）
-bindir <dir> ......... Executables [PREFIX/bin]
-headerdir <dir> ...... Header files [PREFIX/include]
-libdir <dir> ......... Libraries [PREFIX/lib]
-archdatadir <dir> .... Arch-dependent data [PREFIX]
-plugindir <dir> ...... Plugins [ARCHDATADIR/plugins]
-libexecdir <dir> ..... Helper programs [ARCHDATADIR/bin on Windows,
ARCHDATADIR/libexec otherwise]
-importdir <dir> ...... QML1 imports [ARCHDATADIR/imports]
-qmldir <dir> ......... QML2 imports [ARCHDATADIR/qml]
-datadir <dir> ........ Arch-independent data [PREFIX]
-docdir <dir> ......... Documentation [DATADIR/doc]
-translationdir <dir> . Translations [DATADIR/translations]
-sysconfdir <dir> ..... Settings used by Qt programs [PREFIX/etc/xdg]
-examplesdir <dir> .... Examples [PREFIX/examples]
-testsdir <dir> ....... Tests [PREFIX/tests]
-hostbindir <dir> ..... Host executables [HOSTPREFIX/bin]
-hostlibdir <dir> ..... Host libraries [HOSTPREFIX/lib]
-hostdatadir <dir> .... Data used by qmake [HOSTPREFIX]
**对剩余的选项的约定：**
当一个选项描述符在一系列方括号内的变量之后，这个选项的解释是：
空选项表示yes； 所有其他值是可能的前缀，比如-no-gui.
Values are listed in the order they are tried if not specified;
'auto' 是 'yes/no'的简写. 单个 'yes' 和 'no' 表示没有自动检测的二进制选项。
**可配置的meta：**
-help, -h ............ Display this help screen
-verbose, -v ......... Print verbose messages during configuration
-continue ............ Continue configure despite errors
-redo ................ Re-configure with previously used options.
Additional options may be passed, but will not be
saved for later use by -redo.
-recheck ............. Discard cached negative configure test results.
Use this after installing missing dependencies.
-recheck-all ......... Discard all cached configure test results.
-feature-<feature> ... Enable <feature>
