# 事先安装好tslib #

# 下载Qt5.12.9源码 #

在Qt下载地址https://download.qt.io/找到https://download.qt.io/archive/qt/5.12/5.12.9/single/，进入下载页面如下。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI4ODc3MTI1_size_16_color_FFFFFF_t_70_pic_center]  
 在 Ubuntu 使用 wget 指令下载 qt-everywhere-src-5.12.9.tar.xz 源码如下。如果觉得慢，就在Windows 下复制下载链接地址使用迅雷下载再拷贝到 Ubuntu 虚拟机吧！

wget https://download.qt.io/archive/qt/5.12/5.12.9/single/qt-everywhere-src-5.12.9.tar.xz

解压下载好的 qt-everywhere-src-5.12.9.tar.xz 源码压缩包。解压时间较长，不是卡住了！

tar xf qt-everywhere-src-5.12.9.tar.xz

在当前目录出现 qt-everywhere-src-5.12.9 目录夹，此文件夹就是我们解压后的目录。进入此目录。

cd qt-everywhere-src-5.12.9/
    ls

# 修改 qmake.conf #

编辑 `mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf`，配置相关编译器及路径。由于用户经常复制文档错误，指的是格式或者手敲错误。所以编者将这些配置上传到 gitee 上，提供给用户下载。  
路径如下：`https://gitee.com/QQ1252699831/qt5.12.9-conf.git`。可以直接在 gitee 上下载这个 qmake.conf。

vi qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

修改成如下，红色加粗部分就是要修改的地方。

#
    # qmake configuration for building with arm-linux-gnueabi-g++
    #
    MAKEFILE_GENERATOR = UNIX
    CONFIG            += incremental
    QMAKE_INCREMENTAL_STYLE = sublib
    
    QT_QPA_DEFAULT_PLATFORM = linuxfb
    QMAKE_CFLAGS += -O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon -mfloat-abi=hard
    QMAKE_CXXFLAGS += -O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon -mfloat-abi=hard
    
    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)

上面还是不得行报错：

只好改成：

#
    # qmake configuration for building with arm-linux-gnueabi-g++
    #
    
    MAKEFILE_GENERATOR      = UNIX
    CONFIG                 += incremental
    QMAKE_INCREMENTAL_STYLE = sublib
    
    QT_QPA_DEFAULT_PLATFORM = linuxfb
    QMAKE_CFLAGS += -O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon -mfloat-abi=hard
    QMAKE_CXXFLAGS += -O2 -march=armv7-a -mtune=cortex-a7 -mfpu=neon -mfloat-abi=hard
    
    include(../common/linux.conf)
    include(../common/gcc-base-unix.conf)
    include(../common/g++-unix.conf)
    
    # modifications to g++.conf
    QMAKE_CC                = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
    QMAKE_CXX               = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
    QMAKE_LINK              = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
    QMAKE_LINK_SHLIB        = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/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)

然后就配置成功了：

    WARNING: Cross compiling without sysroot. Disabling pkg-config
    
    Qt is now configured for building. Just run 'make'.
    Once everything is built, you must run 'make install'.
    Qt will be installed into '/opt/qt5.12.9-arm'.
    
    Prior to reconfiguration, make sure you remove any leftovers from
    the previous build.

# 配置编译选项 #

查看编译选项，输入./configure -help 指令，查看可配置选项。

./configure -help

由于配置较长，按需要编译，编者总结了配置项，写了一个脚本。由于用户经常复制文档错误，指的是 PDF 格式或者手敲错误。所以编者将这些配置上传到 gitee 上，提供给用户下载。路径如下。`https://gitee.com/QQ1252699831/qt5.12.9-conf.git`。可以直接在 gitee 上下载这个 autoconfigure.sh。下载之后修改里面的路径，改为自己的即可！

vi autoconfigure.sh

在这个 autoconfigure.sh 添加以下内容。复制时注意，每行前面不要留空格。

./configure -prefix /opt/qt5.12.9-arm \
    -opensource \
    -confirm-license \

其中以下部分为编者个人的路径，请修改成个人路径。

*  （1） `/opt/qt5.12.9-arm` 为编译输出路径。
 *  （2） `/opt/tslib/include` 为前面安装的 tslib 头文件路径。
 *  （3） `/opt/tslib/lib` 为前面安装的 tslib 相关库文件路径。

赋予脚本可执行权限。

chmod +x autoconfigure.sh

直接执行 autoconfigure.sh。配置需要一段时间，请耐心等待！

sudo apt-get install g++ // 配置前请先安装 g++
    ./autoconfigure.sh

配置完成如下。若未见此信息，请检查个人配置。切记是使用 Ubuntu16，如果是 Ubuntu18 以上，可能出现 C++11 Error，这是我们正点原子忠实用户粉丝反馈的，粉丝解决方法是出现这种错误后，重新解压一次 Qt 源码，重新配置就不会出现 c++11 Error，特此说明。

# 开始编译 Qt5.12.9 源码 #

直接执行 make 开始编译。

time (make -j 16) // -j 16 代表最多允许 16 条编译指令同时运行，参数 16，一般为个人分配给虚拟机的核心数的 2 倍，前面加个 time 是测试编译时间。

编译时长由个人计算机速度及分配给虚拟机核心数决定（编者编译了 8分钟）。如按上面操作，遇到编译 Qt 源码出现错误，请重新配置！有可能是个人计算机分配给虚拟机内存太低所导致的，既然 Qt 源码能发布，除了配置错误，几乎不可能有编译错误的！经过编者经验和用户反馈，用户编译的时候会出现类似 sub-xx-make-first-ordered 错误。这个原因可能是虚拟机分配的配置太低及用户目录权限的问题。您可以看见编者都是用普通用户在编译的，尽量不要使用 root 用户和 sudo 权限来编译！除非您比较懂。编译完成如下图。

# 移植Qt到文件系统 #

上面我们终于编译好了 tslib 和 Qt 源码。我们需要移植这些库都开发板系统上才能运行 Qt应用程序！这里特别说明一下。因为正点原子的出厂系统自带 Qt 库和 tslib，是不需要额外移植了。不能将自己编译的 Qt 库移植到出厂系统下！因为如果您不了解出厂系统的环境，就会导致移植的 Qt 库与出厂的 Qt 冲突！导致报错！所以我们需要移植到一个没有 Qt 库的文件系统里。正点原子 Linux 驱动指南里有编译好的 busybox 文件系统。刚好这个文件系统没有 Qt 库，所以我们直接移植到这个 busybox 文件系统里做实验！
