經過一段漫長而痛苦的過程（幾次差點就要放棄）之後，今天qtopia2.2.0pc版本和ARM-LINUX版本都終於編譯成功了，下面我和大家分享一下pc機版本的qtopia2.2.0編譯過程中的遇到的錯誤及其解決辦法，希望與大家一起進步。（arm-linux版本的編譯參照飛凌提供的6410的qt移植視頻中的五和六，先編譯第三方庫，按照視頻上來就沒有問題，編譯完第三方庫以後，剩下的就和pc版本的相差無幾了）
環境：ubuntu10.10
編譯器： gcc version 4.4.5
主機：奔四
內存：512+256M
VMware版本：7.0
注意事項：
在編譯之前先確保你的ubuntu系統中有X11的SDK庫，Qtopia編譯過程中需要使用X11SDK裏面的一些頭文件,使用以下命令，即可完成安裝：
apt-get install libx11-dev libxext-dev libxtst-dev
另外，在修改完第一處錯誤，重新編譯之前，先修改一下build腳本文件，因爲重新執行build命令，該腳本會把剛纔編譯中的qtopia-free-2.2.0文件夾刪除，重新解壓，形成新的qtopia-free-2.2.0，開始編譯，這樣剛纔的修改就失去意義了。修改build腳本的方法如下：
將 rm -fr qtopia-free-2.2.0
tar xfvz qtopia-free-2.2.0.tar.gz 這兩條語句的前面分別加上# ，註釋掉，保存退出，重新執行 ./build
在編譯過程中會出現很多的錯誤，包括飛凌提供的ok6410 QT移植百科全書裏面的，但是手冊裏面羅列的不全，下面我將我在編譯過程實際遇到的編譯錯誤及其解決辦法寫一下（其中的一些錯誤實際中沒有遇到，是從網上搜集的，供朋友們參考）：
錯誤一：
/usr/bin/ld: cannot find -lXmu
collect2: ld returned 1 exit status
錯誤二：
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：
這是因爲沒有安裝uuid和Xmu，因爲在編譯qtopia2.2.0的過程中需要安裝工具uuid（Universally Unique Identifier,）和 xmu庫文件。
解決辦法：
apt-get install uuid-dev
apt-get install libxmu-dev libxmu6
錯誤三：
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
解決:
在ubuntu裏，zlib叫zlib1g，相應的zlib-devel叫zlib1g.dev
sudo apt-get install zlib1g-dev
錯誤四:
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/aapt_intermediates/aapt] Error 1
解決方法：
sudo apt-get install lib32z1-dev
錯誤五:
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
解決方法:
sudo apt-get install bison
錯誤六:
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
解決方法:
sudo apt-get install flex
錯誤七:
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/adb_intermediates/adb] Error 1
解決方法:
sudo apt-get install lib32ncurses5-dev
錯誤八:
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
解決方法:

錯誤九:

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'
解決方法:
sudo apt-get install gperf
錯誤十：open函數參數不夠
/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
解決辦法：
參見ok6410移植百科全書。
錯誤十一：使用未定義的類
error: ‘QWSInputMethod’ has not been declared
解決辦法：
參見ok6410移植百科全書。 （注： 該文件中使用了這兩個類，C++允許在文件中這樣聲明其他地方定義的類，減少頭文件的相互包含關係，加快編譯速度）
錯誤十二：缺少頭文件
asm/page.h: No such file or directory
解決辦法：
參見ok6410移植百科全書。
錯誤十三：類型轉換錯誤
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: 錯誤：不能從'QValueListIterator<QMap<QString, QString> >'轉換到'const char*'，爲實參'1'(屬於'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: 錯誤：不能從'QValueListIterator<QString>'轉換到'const char*'，爲實參'1'(屬於'int remove(const char*)')
解決辦法：
參見ok6410移植百科全書。
錯誤十四：沒有找到uic工具 錯誤提示：
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
解決辦法：
cd到你的qtopia-free-2.2.0目錄下, find ./ -name uic 會看到其他的目錄下已經有了uic,我把qt3/bin 目錄下的uic拷貝到 qt2/bin下面，即可
（注：我在實際操作過程中，一開始報出這個錯誤，但是將其他的錯誤改完之後，這個錯誤也就自動消失了，我是菜鳥，不知道怎麼回事，
）
錯誤十五： 指針類型轉換出錯：
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
解決辦法：
修改 qtopia-free-2.2.0/qtopia/src/libraries/qtopia/backend/vobject.cpp 文件419行
char *dot = strrchr(g,'.'); 修改爲 char *dot = (char *)strrchr(g,'.');
在編譯過程中還出現了類似的錯誤
wavplugin.cpp:435 : error: invalid conversion from 'const char*' to 'char*'
解決辦法
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
錯誤十六：編譯器找不到QSizePolicy類的五個參數的構造函數
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 & ）
解決辦法：
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() ) );
修改爲：
prompt = new QLabel( this, "prompt" );
prompt->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)7, (QSizePolicy::SizeType)1, prompt->sizePolicy ().hasHeightForWidth() ) );
即去掉0，0 兩個參數
錯誤十七（這是一大類錯誤，在編譯過程中會遇到很多）：g++編譯器提示 有多餘的符號在成員函數前 ,有些編譯器規定C++成員函數前不需要再加這個類的名字
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
解決辦法 ：
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& );
修改後 void paintItem( QPainter*, const QColorGroup& );
** 繼續編譯後會出現類似的錯誤
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
解決辦法：去掉 PhoneTypeSelector::
繼續編譯：
../../../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'

解決辦法：去掉NumberEntryDialog::’
繼續編譯
In file included from addressbook.cpp:40:
ablabel.h: At global scope:
ablabel.h:78: error: extra qualification ‘AbLabel::’ on member ‘decodeHref"
解決辦法：去掉‘AbLabel::’
繼續編譯

minefiled.h:105: error: extra qualification 'MineFiled::' on member
'setState'
minefiled.h:106: error: extra qualification 'MineFiled::' on member
'placeMines'
解決辦法：
編輯 qtopia-free-2.2.0/qtopia/src/games/minesweep/minefiled.h
修改106行和105行： 刪除'MineFiled::'即可
繼續編譯
buttoneditordialog.h:56 error:extra qualification 'ButtonEditorDialog::' on member
'actionFor'
解決辦法：
編輯qtopia-free-2.2.0/qtopia/src/settings/buttoneditor/buttoneditordialog.h
將'ButtonEditorDialog::' 刪除即可
繼續編譯
出現packagewizard.h:106:error: extra qualification 'PackageWizard::' on member
'current'
解決辦法
編輯qtopia-free-2.2.0/qtopia/src/settings/qipkg/packagewizard.h
將'PackageWizard::'刪除即可
繼續編譯
出現 keboard.h:60 error:extra qualification 'KeboardPicks::' on member
'KeboardPicks'
解決辦法
編輯qtopia-free-2.2.0/qtopia/src/plugins/inputmethods/keyboard/keyboard.h
將第60行的'KeboardPicks::'刪除即可
繼續編譯
還會出現類似的錯誤，如extra qualification 'PolishedDecoration::' 、'IMToolButton::'
錯誤十八：未經定義的構造函數錯誤提示

cancelButton->setSizePolicy( QSizePolicy( (QSizePolicy::SizeType)3, (QSizePolicy::SizeType)0, 0, 0, cancelButton->sizePolicy().hasHeightForWidth() ) );

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