qtopia2.2.0编译成功，分享一下经验

经过一段漫长而痛苦的过程（几次差点就要放弃）之后，今天qtopia2.2.0pc版本和ARM-LINUX版本都终于编译成功了，下面我和大家分享一下pc机版本的qtopia2.2.0编译过程中的遇到的错误及其解决办法，希望与大家一起进步。（arm-linux版本的编译参照飞凌提供的6410的qt移植视频中的五和六，先编译第三方库，按照视频上来就没有问题，编译完第三方库以后，剩下的就和pc版本的相差无几了）

环境：ubuntu10.10
编译器： gcc version 4.4.5
主机：奔四
内存：512+256M
VMware版本：7.0

注意事项：
在编译之前先确保你的ubuntu系统中有X11的SDK库，Qtopia编译过程中需要使用X11SDK里面的一些头文件,使用以下命令，即可完成安装：
apt-get install libx11-dev libxext-dev libxtst-dev

另外，在修改完第一处错误，重新编译之前，先修改一下build脚本文件，因为重新执行build命令，该脚本会把刚才编译中的qtopia-free-2.2.0文件夹删除，重新解压，形成新的qtopia-free-2.2.0，开始编译，这样刚才的修改就失去意义了。修改build脚本的方法如下：
将 rm -fr qtopia-free-2.2.0
tar xfvz qtopia-free-2.2.0.tar.gz 这两条语句的前面分别加上# ，注释掉，保存退出，重新执行 ./build

在编译过程中会出现很多的错误，包括飞凌提供的ok6410 QT移植百科全书里面的，但是手册里面罗列的不全，下面我将我在编译过程实际遇到的编译错误及其解决办法写一下（其中的一些错误实际中没有遇到，是从网上搜集的，供朋友们参考）：

错误一：
/usr/bin/ld: cannot find -lXmu
collect2: ld returned 1 exit status
错误二：
Creating pngscale...make[1]: Entering directory `/root/yizhi/qtopia-free-2.2.0/qtopia/util/pngscale'
..make[1]: *** [../../bin/pngscale] Error 1
make[1]: Leaving directory `/root/yizhi/qtopia-free-2.2.0/qtopia/util/pngscale'
Failed to make pngscale
分析：
这是因为没有安装uuid和Xmu，因为在编译qtopia2.2.0的过程中需要安装工具uuid（Universally Unique Identifier,）和 xmu库文件。
解决办法：

apt-get install uuid-dev
apt-get install libxmu-dev libxmu6

错误三：
external/clearsilver/cgi/cgi.c:22: fatal error: zlib.h: No such file or directory
compilation terminated.
make: *** [out/host/linux-x86/obj/SHARED_LIBRARIES/libneo_cgi_intermediates/cgi.o] Error 1

解决:
在ubuntu里，zlib叫zlib1g，相应的zlib-devel叫zlib1g.dev

sudo apt-get install zlib1g-dev

错误四:
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt] Error 1

解决方法：
sudo apt-get install lib32z1-dev

错误五:
bison -d -o out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_y.cpp frameworks/base/tools/aidl/aidl_language_y.y
/bin/bash: bison: command not found
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_y.cpp] Error 127

解决方法:
sudo apt-get install bison

错误六:
Lex: aidl <= frameworks/base/tools/aidl/aidl_language_l.l
/bin/bash: flex: command not found
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Error 127

解决方法:
sudo apt-get install flex

错误七:
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/adb_intermediates/adb] Error 1

解决方法:
sudo apt-get install lib32ncurses5-dev

错误八:
prebuilt/linux-x86/sdl/include/SDL/SDL_syswm.h:55: fatal error: X11/Xlib.h: No such file or directory
compilation terminated.
make: *** [out/host/linux-x86/obj/EXECUTABLES/emulator_intermediates/android/main-common.o] Error 1

解决方法:
sudo apt-get install libx11-dev

错误九:
sh: gperf: not found
calling gperf failed: 32512 at ./makeprop.pl line 96.
make: *** [out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/WebCore/css/CSSPropertyNames.h] Error 25
make: *** Deleting file `out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/WebCore/css/CSSPropertyNames.h'

解决方法:
sudo apt-get install gperf

错误十：open函数参数不够

/usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs 3 arguments

解决办法：
参见ok6410移植百科全书。

错误十一：使用未定义的类

error: ‘QWSInputMethod’ has not been declared
解决办法：
参见ok6410移植百科全书。 （注： 该文件中使用了这两个类，C++允许在文件中这样声明其他地方定义的类，减少头文件的相互包含关系，加快编译速度）

错误十二：缺少头文件
asm/page.h: No such file or directory
解决办法：
参见ok6410移植百科全书。

错误十三：类型转换错误
home/work/armqt/qtlibsource/qt-x11/include/qvalue stack.h: In member function 'T QValueStack<T>::pop() [with T = QMap<QString, QString>]':
xml/qxml.cpp:513: instantiated from here
　　/home/work/armqt/qtlibsource/qt-x11/include/qvalue stack.h:57: 错误：不能从'QValueListIterator<QMap<QString, QString> >'转换到'const char*'，为实参'1'(属于'int remove(const char*)')
/home/work/armqt/qtlibsource/qt-x11/include/qvalue stack.h: In member function 'T QValueStack<T>::pop() [with T = QString]':
xml/qxml.cpp:2502: instantiated from here
　　/home/work/armqt/qtlibsource/qt-x11/include/qvalue stack.h:57: 错误：不能从'QValueListIterator<QString>'转换到'const char*'，为实参'1'(属于'int remove(const char*)')
解决办法：
参见ok6410移植百科全书。

错误十四：没有找到uic工具 错误提示：

make[5]: /root/yizhi/host/qtopia-free-2.2.0/qt2/bin/uic: Command not found
make[5]: *** [../../../include/qtopia/private/passwordbase_p.h] Error 127
解决办法：
cd到你的qtopia-free-2.2.0目录下, find ./ -name uic 会看到其他的目录下已经有了uic,我把qt3/bin 目录下的uic拷贝到 qt2/bin下面，即可
（注：我在实际操作过程中，一开始报出这个错误，但是将其他的错误改完之后，这个错误也就自动消失了，我是菜鸟，不知道怎么回事，

）

错误十五： 指针类型转换出错：
backend/vobject.cpp: In function ‘VObject* addGroup(VObject*, const char*)’:
backend/vobject.cpp:419: error: invalid conversion from ‘const char*’ to ‘char*’
backend/vobject.cpp: In function ‘void writeEncString(OFi

解决办法：
修改 qtopia-free-2.2.0/qtopia/src/libraries/qtopia/backend/vobject.cpp 文件419行
char *dot = strrchr(g,'.'); 修改为 char *dot = (char *)strrchr(g,'.');

在编译过程中还出现了类似的错误
wavplugin.cpp:435 : error: invalid conversion from 'const char*' to 'char*'
解决办法
修改qtopia-free-2.2.0/qtopia/src/plugins/codes/wavplugin/wavplugin.cpp文件的第435行
修改方法如上

错误十六：编译器找不到QSizePolicy类的五个参数的构造函数

ui/release-shared/passwordbase_p.cpp:35: error: no matching function for call to ‘QSizePolicy:

SizePolicy(QSizePolicy::SizeType, QSizePolicy::SizeType, int, int, bool)’
/root/yizhi/host/qtopia-free-2.2.0/qt2/include/qsizepolicy.h:93: note: candidates are: QSizePolicy:

SizePolicy(int)
/root/yizhi/host/qtopia-free-2.2.0/qt2/include/qsizepolicy.h:99: note: QSizePolicy:

SizePolicy(QSizePolicy::SizeType, QSizePolicy::SizeType, bool)
/root/yizhi/host/qtopia-free-2.2.0/qt2/include/qsizepolicy.h:63: note: QSizePolicy:

SizePolicy()
/root/yizhi/host/qtopia-free-2.2.0/qt2/include/qsizepolicy.h:46: note: QSizePolicy:

SizePolicy(const QSizePolicy & ）

解决办法：

qtopia-free-2.2.0/qtopia/src/libraries/qtopia/.ui/release-shared/passwordbase_p.cpp 文件中的38行位置
prompt = new QLabel( this, "prompt" );
prompt->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)7, (QSizePolicy::SizeType)1, 0, 0, prompt->sizePolicy().hasHeightForWidth() ) );

修改为：

prompt = new QLabel( this, "prompt" );
prompt->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)7, (QSizePolicy::SizeType)1, prompt->sizePolicy ().hasHeightForWidth() ) );

即去掉0，0 两个参数

错误十七（这是一大类错误，在编译过程中会遇到很多）：g++编译器提示 有多余的符号在成员函数前 ,有些编译器规定C++成员函数前不需要再加这个类的名字

thumbnailview_p.h: At global scope:
thumbnailview_p.h:81: error: extra qualification ‘ThumbnailItem::’ on member ‘paintItem’
make[5]: *** [.obj/release-shared/imageselector.o] Eopia/src

解决办法 ：

qtopia-free-2.2.0/qtopia/src/libraries/qtopia2/thumbnailview_p.h文件中第81行：

修改 void ThumbnailItem::paintItem( QPainter*, const QColorGroup& );

修改后 void paintItem( QPainter*, const QColorGroup& );

** 继续编译后会出现类似的错误

abtable_p.h:276: error: extra qualification ‘PhoneTypeSelector::’ on member ‘addType’
make[5]: *** [.obj/release-shared/abtable.o] Error 1
make[5]: Leaving directory `/root/yizhi/host/qtopia-free-2.2.0/qtopia/src/libraries/qtopiapim'
make[4]: *** [all] Error 2
解决办法：去掉 PhoneTypeSelector::

继续编译：
../../../include/qtopia/pim/private/../../../../src/libraries/qtopiapim/numberentry_p.h: At global scope:
../../../include/qtopia/pim/private/../../../../src/libraries/qtopiapim/numberentry_p.h:106: error: extra qualification ‘NumberEntryDialog::’ on member ‘eventFilter’

make[5]: Leaving directory `/root/yizhi/host/qtopia-free-2.2.0/qtopia/src/libraries/qtopiapim'
make[4]: *** [all] Error 2

解决办法：去掉NumberEntryDialog::’

继续编译
In file included from addressbook.cpp:40:
ablabel.h: At global scope:
ablabel.h:78: error: extra qualification ‘AbLabel::’ on member ‘decodeHref"

解决办法：去掉‘AbLabel::’

继续编译
In file include from minefiled.cpp:35
minefiled.h:105: error: extra qualification 'MineFiled::' on member
'setState'
minefiled.h:106: error: extra qualification 'MineFiled::' on member
'placeMines'

解决办法：
编辑 qtopia-free-2.2.0/qtopia/src/games/minesweep/minefiled.h
修改106行和105行： 删除'MineFiled::'即可

继续编译
buttoneditordialog.h:56 error:extra qualification 'ButtonEditorDialog::' on member
'actionFor'
解决办法：
编辑qtopia-free-2.2.0/qtopia/src/settings/buttoneditor/buttoneditordialog.h
将'ButtonEditorDialog::' 删除即可

继续编译
出现packagewizard.h:106:error: extra qualification 'PackageWizard::' on member
'current'
解决办法
编辑qtopia-free-2.2.0/qtopia/src/settings/qipkg/packagewizard.h
将'PackageWizard::'删除即可

继续编译
出现 keboard.h:60 error:extra qualification 'KeboardPicks::' on member
'KeboardPicks'
解决办法
编辑qtopia-free-2.2.0/qtopia/src/plugins/inputmethods/keyboard/keyboard.h
将第60行的'KeboardPicks::'删除即可

继续编译
还会出现类似的错误，如extra qualification 'PolishedDecoration::' 、'IMToolButton::'

错误十八：未经定义的构造函数错误提示

okButton = new QPushButton( this, "okButton" );
okButton->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)3, (QSizePolicy::SizeType)0, 0, 0, okButton->sizePolicy().hasHeightForWidth() ) );
Layout2->addWidget( okButton );

cancelButton = new QPushButton( this, "cancelButton" );
cancelButton->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)3, (QSizePolicy::SizeType)0, 0, 0, cancelButton->sizePolicy().hasHeightForWidth() ) );
Layout2->addWidget( cancelButton );

修改为

okButton = new QPushButton( this, "okButton" );
okButton->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)3, (QSizePolicy::SizeType)0,okButton->sizePolicy().hasHeightForWidth() ) );
Layout2->addWidget( okButton );
