编译Qt5.4 for IFC6410

一、编译Qt5.4 forIFC6410

环境变量

exportQT_SYSROOT=/home/gang/IFC6410/qt-5.4-sysroot

exportMONTFOLDER=/home/gang/IFC6410/ImgMountFolder

exportQT_INSTALL_DIR=/home/gang/IFC6410/qt-5.4-for-ifc6410-installed

exportARCH=arm

exportCROSS_COMPILE=/home/gang/IFC6410/toolchain/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-

 

1.解压img

sudo apt-get installandroid-tools-fsutils

 

simg2imglinaro-trusty-gnome-ifc6410-20141024-37.imglinaro-trusty-gnome-ifc6410-20141024-37.img.raw

2.挂在至目录

mount -oloop/home/gaea/IFC6410/ifc-pre-images/IFC6410_Ubuntu_Linux_BSP_880310_V1.3/IFC6410_Ubuntu_Linux_BSP_880310_V1.3/binaries/linaro-trusty-gnome-ifc6410-20141024-37.img.raw/home/gaea/IFC6410/qt5.4-for-ifc6410/ImgMountFolder

 

3.配置qt源码配置文件

qtbase->mkspec->device->ifc-linux->qmake.conf

 

#

# qmakeconfiguration for building with arm-linux-gnueabi-g++

#

 

MAKEFILE_GENERATOR     = UNIX

CONFIG                += incremental

QMAKE_INCREMENTAL_STYLE = sublib

 

include(../../common/linux.conf)

include(../../common/gcc-base-unix.conf)

include(../../common/g++-unix.conf)

 

#CROSS_COMPILE=/home/gaea/IFC6410/qt5.4-for-ifc6410/toolchain/gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/arm-linux-gnueabihf-

CROSS_COMPILE=/home/gaea/IFC6410/qt5.4-for-ifc6410/toolchain/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-

QTSYSROOT=/home/gaea/IFC6410/qt5.4-for-ifc6410/qt5.4-sysroot

4.检查环境变量

echo  $QT_INSTALL_DIR

echo$CROSS_COMPILE

echo$ARCH

echo$QT_SYSROOT

 

5.配置Qt源码

./configure-v --prefix=/qt5.4-for-ifc6410-installed -confirm-license -opensource -device ifc-linux -device-optionCROSS_COMPILE=/home/gaea/IFC6410/qt5.4-for-ifc6410/toolchain/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf--opengl es2 -eglfs -no-c++11 -optimized-qmake -qreal float -sysroot/home/gaea/IFC6410/qt5.4-for-ifc6410/qt5.4-sysroot -qt-xcb-no-gcc-sysroot -qt-zlib -no-dbus

 

6.提示找不到库，在${MONTFOLDER}/usr/lib/arm-linux-gnueabihf目录下创建软链接（去除版本号版本）

ls*X11

ln -sAAA.so.1.1 AAA.so

解决所有找不到库文件

找不到-lxcb-aux  -lxcb-atom   -lxcb-property  -lxcb-event   

最终添加

QMAKE_LIBS= -lcap -lcidn -lcom_err -lc_nonshared -lm -lc -ldl -lpthread-lld-linux -lld-linux-armhf -lffi -lwayland-egl -lwayland-client-lwayland-server -ldrm -ldrm_nouveau -ldrm_freedreno -lxcb-xfixes-lxcb-dri2 -lxcb-dri3 -lgbm -lXau -lX11-xcb -lXdmcp -lxcb -lX11-lxcb-shm -lXrender -lxcb-render-util -lxcb-render -lxcb-icccm-lxcb-util -lXi -lXext -lxcb-icccm

 

 

7.检查configure配置结果

make-j4

makeinstall

 问题记录

问题一：

-qt-xcb   必须依赖项 libxcb.so，按照此方式添加其他依赖库，以及修改链接名字

 1123  cdmesa-egl/

 1124  ll

 1125  ln -s libEGL.so.1libEGL.so

 1126  ln -slibGLESv1_CM.so.1.1.0 libGLESv1_CM.so

 1127  ln -slibGLESv2.so.2.0.0 libGLESv2.so

 1128  ln -slibOpenVG.so.1.0.0 libOpenVG.so

 1129  cd ..

 1130  ln -slibxcb.so.1.1.0 libxcb.so

 1131  ln -slibXau.so.6.0.0 libXau.so

 1132  ln -slibXdmcp.so.6.0.0 libXdmcp.so

 

问题二：解决方法是修改libc的依赖库，我先删除了目录下的libc文件，然后创建了toolchain中的依赖库，然后再删除toolchain中的libc.so，再添加rootfs中的libc-2.19,再修改编译参数为：

QMAKE_LIBS +=-L$${MONTFOLDER}/usr/lib/arm-linux-gnueabihf-L$${MONTFOLDER}/lib/arm-linux-gnueabihf -dynamic-linker -lc-2.19-lXau -lXdmcp -lpthread -lxcb-dri2 \

      -lX11-xcb \

      -lxcb-xfixes \

      -lwayland-client \

      -lwayland-server \

      -lgbm \

      -ldl \

      -ldrm \

      -lld-linux-armhf \

      -lffi \

      -lrt \

      -lgcc_s \

      -lXrender \

      -lXi \

      -lXext \

二、IFC6410开发板环境配置

1.配置lib加载路径

sudo vi /etc/ld.so.conf

添加qt5.4 的lib文件夹

sudo ldconfig生效

2.拷贝plugin/platforms路径到执行路径下（或者添加环境变量）

 

 

3.设置环境变量

export QTDIR=

export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib

exportQWS_DISPLAY="LinuxFB:mmWidth200:0"

 

 

3.1.qt的触摸屏和指针环境变量bash文件

#!/bin/sh

 

if [ -c /dev/input/event0 ]; then

   INPUT_PATH=/dev/input

else

   INPUT_PATH=/dev

fi

 

export TSLIB_TSDEVICE=/dev/input/event1

export TSLIB_CONFFILE=/etc/ts.conf

export TSLIB_PLUGINDIR=/lib/ts

export TSLIB_CALIBFILE=/etc/pointercal

exportQTDIR=/usr/local/Trolltech/QtEmbedded-4.8.6-arm/

export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib

exportQWS_MOUSE_PROTO="Tslib:$INPUT_PATH/event1"

#export QWS_MOUSE_PROTO="Tslib:$INPUT_PATH/event1MouseMan:$INPUT_PATH/mouse1"

export QWS_KEYBOARD=TTY:/dev/tty1

 

#sync font size with QtDesigner

exportQWS_DISPLAY="LinuxFB:mmWidth200:0"

#export QWS_SIZE="480x272"

 

export KDEDIR=/opt/kde

export HOME=/root

GDB

5.1. wget http://ftp.gnu.org/gnu/gdb/gdb-7.8.2.tar.gz

5.2. ./configure --target=arm-linux-gnueabihf--with-python

make

sudo make installed

 

 

安装到默认位置，否则有可能找不到python

默认位置在/usr/local/bin/arm-linux-gdb

 

GDBSERVER

sudo apt-get install gdbserver

三、编写Qt程序配置

1.在pro文件中添加

target.path =/home/linaro

INSTALLS +=target

2.解决中文字体乱码

拷贝一个ttf文件到qt安装目录下/lib/lonts下，并将原目录下的所有字体备份删除（保证此目录只有一个字体，否则需要程序指定使用哪一个字体）

 

QGuiApplicationapp(argc, argv);

QQuickViewview;

// Load theembedded font.

QString fontPath= ":/fonts/MyFont.ttf";

int fontId =QFontDatabase::addApplicationFont(fontPath);

if (fontId !=-1)

{

   QFont font("MyFont");

   app.setFont(font);

}
