Qt4.8.2基于Linux平台下的移植

 

Qt4.8.2基于Linux平台下的移植

1、 下载安装包qt-everywhere-opensource-src-4.8.2：http://download.qt.io/archive/qt/4.8/4.8.2/

2、 拷贝到linux下并解压得到目录：qt-everywhere-opensource-src-4.8.2

3、 进入到：qt-everywhere-opensource-src-4.8.2

4、 修改文件：mkspec/qws/linux-arm-g++/qmake.conf指定交叉编译工具链及添加第三方库，例：

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

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

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

include(../../common/qws.conf)

QMAKE_CC                = arm-linux-gcc

QMAKE_CXX               = arm-linux-g++

QMAKE_LINK              = arm-linux-g++

QMAKE_LINK_SHLIB        = arm-linux-g++

QMAKE_CFLAGS           += -march=armv7 -mtune=cortex-a9

QMAKE_CFLAGS_DEBUG     += -march=armv7 -mtune=cortex-a9 -g

QMAKE_CFLAGS_RELEASE   += -march=armv7 -mtune=cortex-a9

QMAKE_CXXFLAGS         += -march=armv7 -mtune=cortex-a9

QMAKE_CXXFLAGS_DEBUG   += -march=armv7 -mtune=cortex-a9 -g

QMAKE_CXXFLAGS_RELEASE +=-march=armv7 -mtune=cortex-a9

QMAKE_AR                = arm-linux-ar cqs

QMAKE_OBJCOPY           = arm-linux-objcopy

QMAKE_STRIP              =arm-linux-strip

QMAKE_INCDIR           += /freetype/include

QMAKE_INCDIR              += /freetype/include/freetype2

QMAKE_INCDIR           += /zlib/include

QMAKE_INCDIR           += /dbus/include/dbus-1.0

QMAKE_INCDIR           += /bzip2/include

QMAKE_LIBDIR           +=/zlib/usr/lib

QMAKE_LIBDIR           += /freetype/usr/lib

QMAKE_LIBDIR           += /bus/usr/lib

QMAKE_LIBDIR           += /bzip2/usr/lib

QMAKE_LIBS             += -ldbus-1

QMAKE_LIBS             += -lfreetype

QMAKE_LIBS             += -lz

QMAKE_LIBS             += -lbz2

 

5、 修改configure，解决连接dbus问题

Creating qmake. Please wait...
gmake: Nothing to be done for `first'.
The QtDBus module cannot be enabled because libdbus-1 version 0.93 was not found.
 Turn on verbose messaging (-v) to ./configure to see the final report.
 If you believe this message is in error you may use the continue
 switch (-continue) to ./configure to continue.

出现该问题的原因是在configure中dbus路径指定错误

 

Configure中5660行添加打印，查看结果：

if ["$CFG_DBUS" != "no" ]; then

    if [ -n "$PKG_CONFIG" ]&& $PKG_CONFIG --atleast-version="$MIN_DBUS_1_VERSION" dbus-12>/dev/null; then

        QT_CFLAGS_DBUS=`$PKG_CONFIG --cflagsdbus-1 2>/dev/null`

        QT_LIBS_DBUS=`$PKG_CONFIG--libs dbus-1 2>/dev/null`

       echo"QT_CFLAGS_DBUS====="$QT_CFLAGS_DBUS

       echo "QT_LIBS_DBUS====="$QT_LIBS_DBUS

    fi

    if "$unixtests/compile.test""$XQMAKESPEC" "$QMAKE_CONFIG" $OPT_VERBOSE"$relpath" "$outpath" config.tests/unix/dbus"D-Bus" $L_FLAGS $I_FLAGS $l_FLAGS $QT_CFLAGS_DBUS $QT_LIBS_DBUS$MAC_CONFIG_TEST_COMMANDLINE; then

        [ "$CFG_DBUS" ="auto" ] && CFG_DBUS=yes

        QMakeVar set QT_CFLAGS_DBUS"$QT_CFLAGS_DBUS"

        QMakeVar set QT_LIBS_DBUS"$QT_LIBS_DBUS"

    else

        if [ "$CFG_DBUS" ="auto" ]; then

            CFG_DBUS=no

        elif ["$CFG_CONFIGURE_EXIT_ON_ERROR" = "yes" ]; then

            # CFG_DBUS is "yes" or"linked" here

            echo "The QtDBus module cannotbe enabled because libdbus-1 version $MIN_DBUS_1_VERSION was not found."

            echo " Turn on verbosemessaging (-v) to $0 to see the final report."

            echo " If you believe thismessage is in error you may use the continue"

            echo " switch (-continue) to$0 to continue."

           exit101

        fi

    fi

fi

如果错误，可直接修改：QT_CFLAGS_DBUS   QT_LIBS_DBUS

 

6、 配置，如：

 ./configure \

     -prefix /usr/local/qt4.8.2-embedded\

   -host-little-endian \

   -little-endian \

   -opensource \

    -confirm-license \

    -no-rpath \

    -shared \

    -fast \

    -optimized-qmake \

    -embedded armv7 \

    -xplatform qws/linux-arm-g++\

    -qt-kbd-linuxinput \

    -qt-mouse-pc \

    -no-qt3support \

    -no-javascript-jit \

    -no-phonon \

    -no-webkit \

    -no-declarative \

    -no-declarative-debug \

   -release \

   -nomake examples \

   -dbus-linked \

   -system-freetype \

   -system-zlib \

7、 make –jN

8、 make install

/usr/local/qt4.8.2-embedded目录下即编译好的库
