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：

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。
