基于Hisi3521DV200平台移植Qt4.8.6

近日，因方案变更，需要移植Qt4.8.6到Hisi3521DV200平台上；而之前开发的GUI界面，都没有触摸功能，本次开发打算将触摸功能也一并实现。

1.安装交叉编译链arm-himix400-linux-g++：

• 一般HIsiSDK包都有交叉编译链与安装指导，不做赘述。

2.交叉编译，安装tslib

• 见另一篇文章：https://www.cnblogs.com/-Newbie/p/12942621.html

3.下载Qt源码：

• 下载链接：http://download.qt.io/archive/qt/4.8/4.8.6/
• 源码包：qt-everywhere-opensource-src-4.8.6.tar.gz

4.解压Qt，并修改io.pri文件：src/corelib/io/io.pri

• 从     
      linux-*:!symbian {
              SOURCES += \
                      io/qfilesystemwatcher_inotify.cpp \
                      io/qfilesystemwatcher_dnotify.cpp
  
              HEADERS += \
                      io/qfilesystemwatcher_inotify_p.h \
                      io/qfilesystemwatcher_dnotify_p.h
          }
  改为
          linux-*|arm-himix400-linux-*:!symbian {
              SOURCES += \
                      io/qfilesystemwatcher_inotify.cpp \
                      io/qfilesystemwatcher_dnotify.cpp
  
              HEADERS += \
                      io/qfilesystemwatcher_inotify_p.h \
                      io/qfilesystemwatcher_dnotify_p.h
          }

5.创建专属arm-himix400-linux-g++编译链的qmake.conf文件

• 创建arm-himix400-linux-g++的qmake.cof文件： cp mkspecs/qws/linux-arm-gnueabi-g++/   mkspecs/qws/arm-himix400-linux-g++/ -r
• 修改mkspecs/qws/arm-hisiv300-linux-g++/qmake.conf文件，如下：

• #
  # qmake configuration for building with arm-none-linux-gnueabi-g++
  #
  
  include(../../common/linux.conf)
  include(../../common/gcc-base-unix.conf)
  include(../../common/g++-unix.conf)
  include(../../common/qws.conf)
  
  # modifications to g++.conf
  QMAKE_CC                = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-gcc -lts
  QMAKE_CXX               = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-g++ -lts
  QMAKE_LINK              = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-g++ -lts
  QMAKE_LINK_SHLIB        = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-g++ -lts
  
  # modifications to linux.conf
  QMAKE_AR                = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-ar cqs
  QMAKE_OBJCOPY           = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-objcopy
  QMAKE_STRIP             = /opt/hisi-linux/x86-arm/arm-himix400-linux/bin/arm-himix400-linux-strip
  
  load(qt_config)

6.设定交叉编译配置参数

• ./configure \
  -opensource  \
  --prefix=/opt/qt4.8.6_a15 \
  -confirm-license \
  -qt-sql-sqlite \
  -qt-gfx-linuxfb \
  -qt-gfx-transformed \
  -plugin-sql-sqlite \
  -no-qt3support \
  -no-phonon \
  -no-svg \
  -no-webkit \
  -no-script \
  -no-scripttools \
  -no-declarative \
  -no-declarative-debug \
  -qt-zlib  \
  -qt-libtiff \
  -qt-libpng \
  -no-libmng \
  -qt-libjpeg \
  -no-rpath \
  -no-pch \
  -no-3dnow \
  -no-avx \
  -no-neon \
  -no-openssl \
  -no-nis \
  -no-cups \
  -no-dbus \
  -embedded arm \
  -platform linux-g++ \
  -xplatform qws/arm-himix400-linux-g++ \
  -little-endian \
  -qt-freetype \
  -no-opengl \
  -no-glib \
  -nomake demos \
  -nomake examples \
  -nomake docs \
  -nomake tools \
  -nomake accessible \
  -qt-mouse-tslib \
  -L/home/newbie/Desktop/tslib/arm-himix400-linux-target/lib \
  -I/home/newbie/Desktop/tslib/arm-himix400-linux-target/include 

7.编译与安装

• make && make install

8.问题与处理方法

• 问题

  Makefile:2519: recipe for target '.obj/release-shared-emb-arm/itemviews.o' failed
  make[3]: *** [.obj/release-shared-emb-arm/itemviews.o] Error 1
  make[3]: Leaving directory '/home/newbie/Desktop/qt-everywhere-opensource-src-4.8.6/src/plugins/accessible/widgets'
  Makefile:39: recipe for target 'sub-widgets-make_default' failed
  make[2]: *** [sub-widgets-make_default] Error 2
  make[2]: Leaving directory '/home/newbie/Desktop/qt-everywhere-opensource-src-4.8.6/src/plugins/accessible'
  Makefile:246: recipe for target 'sub-accessible-make_default' failed
  make[1]: *** [sub-accessible-make_default] Error 2
  make[1]: Leaving directory '/home/newbie/Desktop/qt-everywhere-opensource-src-4.8.6/src/plugins'
  Makefile:448: recipe for target 'sub-plugins-make_default-ordered' failed
  make: *** [sub-plugins-make_default-ordered] Error 2

• 解决方案

• 因之前的arm-hisiv300-linux-*与arm-hisiv500-linux-*都没有遇到这种情况，一开始束手无策。

• 从以上报错信息能够看出，在目录/home/newbie/Desktop/qt-everywhere-opensource-src-4.8.6/src/plugins/accessible/widgets编译报错。
• cd /home/newbie/Desktop/qt-everywhere-opensource-src-4.8.6/src/plugins/accessible/widgets && make
• 
• 根据报错内容，修改文件itemviews.cpp：

  从
  bool QAccessibleTable2::unselectColumn(int column)
  {
      if (!view()->model() || !view()->selectionModel())
          return false;
      QModelIndex index = view()->model()->index(0, column, view()->rootIndex());
      if (!index.isValid() || view()->selectionMode() & QAbstractItemView::NoSelection)
          return false;
      view()->selectionModel()->select(index, QItemSelectionModel::Columns & QItemSelectionModel::Deselect);
  
      return true;
  }
  改为：
  bool QAccessibleTable2::unselectColumn(int column)
  {
      if (!view()->model() || !view()->selectionModel())
          return false;
      QModelIndex index = view()->model()->index(0, column, view()->rootIndex());
      if (!index.isValid() || view()->selectionMode() & QAbstractItemView::NoSelection)
          return false;
      view()->selectionModel()->select(index,QItemSelectionModel::SelectionFlags(QItemSelectionModel::Columns & QItemSelectionModel::Deselect));
  
      return true;
  }

   

• 重新编译安装，即可。
