基于Ixm6q，移植Qt5.9.1（动态库）

一、准备好Qt5.9.1与tslib库

1.方法1：

Qt5.9.1源码下载路径：http://download.qt.io/archive/qt/5.9/5.9.1/single/
QtCreator5.9.1：http://download.qt.io/official_releases/qt/5.9/5.9.1/
tslib下载路径：https://github.com/kergoth/tslib

　　2.方法2：

链接：https://pan.baidu.com/s/13-4vFnQ4eErShMn-B4Pc1w
提取码：mck3

二、配置Ixm6q开发环境

　　1.使能Ixm6q开发环境：

source /opt/fsl-imx/4.1.15-2.1.0/fb/environment-setup-cortexa9hf-neon-poky-linux-gnueabi

　　2.测试编译链：

运行命令：echo $CC
结果：arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/opt/fsl-imx/4.1.15-2.1.0/fb/sysroots/cortexa9hf-neon-poky-linux-gnueabi

三、安装tslib

详细安装过程，可参考：https://blog.csdn.net/lincuiting06/article/details/50352557

四、解压Qt5.9.1

下载源码包qt-everywhere-opensource-src-5.9.1.tar.xz，并将源码包拷贝到Ubuntu的Desktop。
解压qt-everywhere-opensource-src-5.9.1.tar.xz
修改解压后源码包权限：sudo chmod 755 qt-everywhere-opensource-src-5.9.1 -R

五、配置qmake.conf交叉编译参数

进入源码包：cd ~/Desktop/qt-everywhere-opensource-src-5.9.1
拷贝创建arm-poky-linux-gnueabi-g++，命令cp qtbase/mkspecs/linux-arm-gnueabi-g++/ qtbase/mkspecs/arm-poky-linux-gnueabi-g++/ -r
修改qtbase/mkspecs/arm-poky-linux-gnueabi-g++/qmake.conf文件

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
 
#Ixm6系统开发环境配置参数
IMX6_CFLAGS             = -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1
IMX6_CFLAGS_RELEASE     = -O2 $$IMX6_CFLAGS
QMAKE_CFLAGS_RELEASE   += $$IMX6_CFLAGS_RELEASE
QMAKE_CXXFLAGS_RELEASE += $$IMX6_CFLAGS_RELEASE
QMAKE_CFLAGS_DEBUG     += $$IMX6_CFLAGS
QMAKE_CXXFLAGS_DEBUG   += $$IMX6_CFLAGS
 
CPPFLAGS = -DNDEBUG -g2 -O3 
CFLAGS = -ffunction-sections -fdata-sections 
CXXFLAGS = -ffunction-sections -fdata-sections 
LDFLAGS = -gc-sections 
 
QMAKE_INCDIR            = /qt5.9.1/usr/include
QMAKE_LIBDIR            = /qt5.9.1/lib
EGLFS_DEVICE_INTEGRATION = eglfs_viv
 
QT_QPA_DEFAULT_PLATFORM = linuxfb　　　　　　　　#QPA显示插件linuxfb,还有eglf等可选
PKG_CONFIG_SYSROOT_DIR = $SDKTARGETSYSROOT    #ixm6q开发SDK路径：/opt/fsl-imx/4.1.15-2.1.0/fb/sysroots/cortexa9hf-neon-poky-linux-gnueabi
PKG_CONFIG_LIBDIR = /qt5.9.1/usr/local/Qt5.9.1/lib 
 
# modifications to g++.conf
QMAKE_CC                = arm-poky-linux-gnueabi-gcc -O2 -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT
QMAKE_CXX               = arm-poky-linux-gnueabi-g++ -O2 -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT
QMAKE_LINK              = arm-poky-linux-gnueabi-g++ -O2 -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT
QMAKE_LINK_SHLIB        = arm-poky-linux-gnueabi-g++ -O2 -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard --sysroot=$SDKTARGETSYSROOT
 
# modifications to linux.conf
QMAKE_AR                = arm-poky-linux-gnueabi-ar cqs
QMAKE_OBJCOPY           = arm-poky-linux-gnueabi-objcopy
QMAKE_NM                = arm-poky-linux-gnueabi-nm -P
QMAKE_STRIP             = arm-poky-linux-gnueabi-strip
load(qt_config)

六、配置Qt编译选项

配置编译选项

./configure -v -prefix /qt5.9.1 -sysroot /opt/fsl-imx/4.1.15-2.1.0/fb/sysroots/cortexa9hf-neon-poky-linux-gnueabi -xplatform arm-poky-linux-gnueabi-g++ -no-opengl -nomake examples -nomake tools -no-separate-debug-info -qreal float -qt-zlib -skip qtdeclarative -skip qtlocation -no-gtk -no-gstreamer -no-glib -linuxfb -tslib -I/opt/tslib1.4/include -L/opt/tslib1.4/lib -recheck-all

选项简要解析
- 指定Ixm6开发SDK路径：-sysroot /opt/fsl-imx/4.1.15-2.1.0/fb/sysroots/cortexa9hf-neon-poky-linux-gnueabi
- 指定安装路径：-prefix /qt5.9.1，但安装绝对路径是 /opt/fsl-imx/4.1.15-2.1.0/fb/sysroots/cortexa9hf-neon-poky-linux-gnueabi/qt5.9.1
- 指定交叉编译qmake.conf：-xplatform arm-poky-linux-gnueabi-g++
- 指定tslib触摸库（但因没用上触摸库，所以没有测试）：-tslib -I/opt/tslib1.4/include -L/opt/tslib1.4/lib
- 检测所有配置选项：-recheck-all

七、编译与安装

编译：make
安装：make install

八、安装QtCreator

运行安装：sudo ./qt-opensource-linux-x64.run
根据提示，选择安装即可

九、配置QtCreator套件

打开QtCreator，Tools->Options->Build & Run

添加编译链

选择Qt version

配置Qt的套件kit

十、在Ixm6q开发板，配置Qt运行环境及移植Qt库

移植Qt5.9.1库，tslib库及程序运行依赖库到Ixm6q的/usr/local

配置/etc/profile
export TSLIB_ROOT=/usr/local/tslib
export TSLIB_PATH=$TSLIB_ROOT/lib
export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONSOLEDEVICE=none

export QTDIR=/usr/local/Qt5.9.1
export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb1
export QTLIB_PATH=$QTDIR/lib

export FONTCONFIG_PATH=$QTDIR/fontconfig

export LD_LIBRARY_PATH=$TSLIB_PATH:$QTLIB_PATH:$QTRELYLIBS_PATH:$FONTCONFIG_PATH:$LD_LIBRARY_PATH
export PATH=$PATH:$LD_LIBRARY_PATH

十一、Qt程序测试

配置/dev/fb0运行参数

#define MXCFB_SET_GBL_ALPHA     _IOW('F', 0x21, struct mxcfb_gbl_alpha)
#define MXCFB_SET_CLR_KEY       _IOW('F', 0x22, struct mxcfb_color_key)
#define MXCFB_SET_LOC_ALPHA     _IOWR('F', 0x26, struct mxcfb_loc_alpha)

struct mxcfb_gbl_alpha {

    int enable;
    int alpha;
};

struct mxcfb_loc_alpha {

    int enable;
    int alpha_in_pixel;
    unsigned long alpha_phy_addr0;
    unsigned long alpha_phy_addr1;
};

struct mxcfb_color_key {
    
    int enable;
    unsigned int color_key;
};

bool setGuiFbSetup(std::string fbName) {

    int s32Fd = -1;
    if(true == fbName.empty()) {

        return false;
    }

    if(0 > (s32Fd = open(fbName.c_str(),O_RDWR,0))) {

        return false;
    }

    struct fb_var_screeninfo stScreen_info;
    if(ioctl(s32Fd, FBIOGET_VSCREENINFO, &stScreen_info) < 0) {

        close(s32Fd);
        return false;
    }

    stScreen_info.xres = 1920;
    stScreen_info.yres = 1080;
    stScreen_info.xres_virtual = 1920;
    stScreen_info.yres_virtual = 1080;
    stScreen_info.xoffset = 0;
    stScreen_info.yoffset = 0;
    stScreen_info.bits_per_pixel = 16;

    if(ioctl(s32Fd, FBIOPUT_VSCREENINFO, &stScreen_info) < 0) {

        close(s32Fd);
        return false;
    }

    struct mxcfb_gbl_alpha gbl_alpha;
    gbl_alpha.enable = 1;
    gbl_alpha.alpha = 255; // BG opaque
    ioctl(s32Fd, MXCFB_SET_GBL_ALPHA, &gbl_alpha);

    struct mxcfb_color_key key;
    key.enable = 1;
    key.color_key = 0x00000000; // Black
    ioctl(s32Fd, MXCFB_SET_CLR_KEY, &key);
    if(ioctl(s32Fd, FBIOBLANK, FB_BLANK_UNBLANK) < 0) {

        close(s32Fd);
        return false;
    }
    close(s32Fd);
    return true;
}

因Qt5没有自带字库，需要在运行界面之前，加载字库。

void sv_gui::sv_setGuiRunningFontLibrary(const QApplication &a) {

    int s32Index = QFontDatabase::addApplicationFont(":/language/language/wqy-microhei.ttc");
    if (-1 != s32Index) {
        QStringList strList(QFontDatabase::applicationFontFamilies(s32Index));
        if (strList.count() > 0) {
            QFont fontThis(strList.at(0));
            fontThis.setPointSize(32);
            a.setFont(fontThis);
        }
    }
}

程序测试：主要测试移植后的Qt是否能正常出界面
