qt5.5.1在Cortex-a8上移植记录

使用Qt5.5.1源码包进行编译：下载地址 http://download.qt.io/official_releases/qt/

1、进入源码包根目录，配置qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

  1 #  2 # qmake configuration for building with arm-linux-gnueabi-g++  3 #  4   5 MAKEFILE_GENERATOR      = UNIX  6 CONFIG                 += incremental  7 QMAKE_INCREMENTAL_STYLE = sublib  8   9 QT_QPA_DEFAULT_PLATFORM = linuxfb 10 QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a 11 QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a  #cortex-a8 12  13 include(../common/linux.conf) 14 include(../common/gcc-base-unix.conf) 15 include(../common/g++-unix.conf) 16  17 # modifications to g++.conf 18 QMAKE_CC                = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-gcc 19 QMAKE_CXX               = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 20 QMAKE_LINK              = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 21 QMAKE_LINK_SHLIB        = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 22  23 # modifications to linux.c/usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi 24 QMAKE_AR                = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-ar cqs 25 QMAKE_OBJCOPY           = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-objcopy 26 QMAKE_NM                = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-nm -P 27 QMAKE_STRIP             = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-strip 28 load(qt_config)

2、配置编译选项

./configure -release -opensource -xplatform linux-arm-gnueabi-g++ -prefix /usr/local/qt -no-c++11 -no-opengl -no-dbus -no-icu -no-eglfs -no-iconv -I/usr/local/tslib/include -L/usr/local/tslib/lib

3、sudo make -j4 & sudo make install

问题1：make[1]: *** [sub-src-make_first] 错误 2

方案1：主要原因是它依赖的dbus目录没有编译，解决方法如下：
#cd /home/hello/qt-everywhere-opensource-src-5.4.0/qtbase/src/dbus执行下面的
如没有Makefile,执行下面的命令
#../../bin/qmake dbus.pro
然后执行Make.
#make
编译成功后，再切换到/home/hello/qt-everywhere-opensource-src-5.4.0目录下，执行
#make

方案2：-no-dbus   (注：当前使用方案)


问题2：make报错module-qt3d-install_subtargets 错误（参考http://my.oschina.net/u/1177171?disp=2&catalog=0&sort=time&p=1大婶的博客，灰常感谢）
方案1：在编译之前，还有个改动，额。。。qt3d和qtcanvas3d在编译的时候会报错，说是未识别模块，而且嵌入式的没有opengl，识别了也会报错，导致编译失败，而且编译配置参数里面也没有这两个模块的配置。我的解决方法简单粗暴，在配置时参数加-no-opengl，然后打开qt-everywhere-opensource-src-5.5.0/qt.pro文件，找到：

addModule(qt3d, qtdeclarative qtimageformats)
addModule(qtcanvas3d, qtdeclarative)

这两行注释掉（#号注释），或者直接删掉。如果不注释掉，即使加了-no-opengl也会报错，编译失败。



问题3：
make[3]: arm-none-linux-gnueabi-g++：命令未找到
make[3]: *** [.pch/Qt5WebChannel.gch/c++] 错误 127
make[3]:正在离开目录 `/home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/qtwebchannel/src/webchannel'
make[2]: *** [sub-webchannel-install_subtargets] 错误 2
make[2]:正在离开目录 `/home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/qtwebchannel/src'
make[1]: *** [sub-src-install_subtargets] 错误 2
make[1]:正在离开目录 `/home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/qtwebchannel'
make: *** [module-qtwebchannel-install_subtargets] 错误 2

方案1：修改qmake.conf文件的交叉编译工具位置，设置为绝对路径错误消除。




4、板卡/etc/profile设置,使用Evdevtouch

echo "Compile usr app (gcc version 4.8.3),Support Qt version 5.5.1"# config qts env parm                                          export QTDIR=/usr/local/qt                                         export QPEDIR=$QTDIR                                               export QT_QWS_FONTDIR=$QTDIR/lib/fonts                                                                                                export QWS_SIZE=1366x768                                           #export QWS_DISPLAY=LinuxFb:/dev/fb0                               export PATH=$QTDIR/bin:$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/binexport LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH                 export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins                        export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0                               export QT_QPA_GENERIC_PLUGINS=EvdevTouch:/dev/input/event1               #export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event1:rotate=180  #可以使触摸屏旋转一定角度90-180-270

5、泰奇克电容触摸屏驱动配置文件/etc/eGTouchL.ini
