Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package.
Tell me:
configure == configure
make == build
make install == install

序：
我这几天编译Qtopia时积累了一些小经验，把编译错误大致分为三类错误：一、因环境变量不起作用及权限不足而导致 二、因缺少类库或安装包不全而导致 三、源代码问题函数错误而导致。
由于编译器版本太高，造成编译Qtopia-2.2.0时，出错很多，但是也只有这样才能够学习到东西，锻炼分析问题，解决问题的能力.但是如果为了节约时间，强烈推荐使用低版本的编译器。
以下为编译x86-qtopia-2.2.0得出经验，编译arm-qtopia-2.2.0时出现的编译错误也可以参考一下对对应内容自行修改。

编译前提:
OS:ubuntu 10.10
GCC:4.3.3
DB:ARM9-TQ2440
SourceCode:Qtopia-2.2.0

首先安装EABI并设置交叉编译器的环境变量：
1、打开环境变量设置文件environment
zyx@zyx:~$ sudo gedit /etc/environment
2、在其中添加":/opt/EmbedSky/4.3.3/bin",修改后为
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/EmbedSky/4.3.3/bin"
3、使修改后的环境变量生效
zyx@zyx:~$ sudo source /etc/environment

一、因环境变量不起作用及权限不足出现编译错误的解决办法:
1.编译错误：
zyx@zyx:~$ sudo ./x86-qtopia-2.2.0-konqueror_build
the qpe program is already !
the konqueror directory is already !
Build konqueror , please wait ...

.: 46: setQpeEnv: not found

原因:配置环境没有起作用。

解决办法：
在x86-qtopia-2.2.0-konqueror_build编译脚本配置文件中
第26行 .setQpeEnv
改成 ./setQpeEnv
重新编译
若不起作用
继续改成  source ./x86-qtopia-2.2.0/setQpeEnv
重新编译
若仍不起作用
就直接将 /opt/EmbedSky/Qte/x86-qtopia-2.2.0/setQpeEnv
的内容 直接copy到此处，再将原来的注释掉
重新编译即可

我的做法：

 

2.编译错误(此为arm编译脚本运行时出现的错误):
chmod: cannot access `set*Env': No such file or directory
 done !
 done !
the konqueror directory is already !
Build konqueror , please wait ...
 
./arm-qtopia-2.2.0-konqueror_build: 58: source: not found

原因:配置环境没有起作用。

解决办法：
在arm-qtopia-2.2.0-konqueror_build编译脚本配置文件中
第25行 source arm-qtopia-2.2.0/setQpeEnv 用＃号注释掉

直接将 /opt/EmbedSky/Qte/arm-qtopia-2.2.0/setQpeEnv
的内容 直接copy到此处，重新编译即可。

3.编译错误(此为arm编译脚本运行时出现的错误):

原因:安装EABI时已安装了交叉编译器并设置了交叉编译器的环境变量，也能够通过命令找到arm-linux-g++和arm-linux-gcc,如下:

zyx@zyx:/opt/EmbedSky$

但是编译的时候就是找不到交叉编译器,这让我很费解；后来在看到网上说有可能是权限不足，在根用户下编译时可以找到g++.这样“configure: error: C compiler cannot create executables
See `config.log' for more details.make: *** No targets specified and no makefile found.  Stop.”的错误也迎刃而解。

解决办法:使用根用户重新编译。
zyx@zyx:/opt/EmbedSky/Qte$ su
Password:
root@zyx:/opt/EmbedSky/Qte# ./arm-qtopia-2.2.0-konqueror_build

4.编译错误：
configure: error: Qt (>= Qt 2.2.2) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

原因:出现此类错有可能是下面讲到的第二大类编译错误第10个错误，但是并不一定都能解决问题。有时是用户权限问题，改成根用户重新编译即可。

解决办法:
zyx@zyx:/opt/EmbedSky/Qte$ su
Password:
root@zyx:/opt/EmbedSky/Qte# ./x86-qtopia-2.2.0-konqueror_build

5.编译错误：
Qtopia data directory is not owned by user 0:/tmp/qtopia-0

原因：权限不足。
解决办法:zyx@zyx:~$ sudo chown root:root /tmp/qtopia-0 然后重启即可。
该类型错误（未验证）：
(1)编译错误:如果运行./qtopia.sh 后提示找不到库文件.解决办法:请从编译器目录下查找，并拷贝到开发板/mnt/yaffs/lib 中，然后重启。

(2)编译错误:can’t open framebuffer device /dev/fb0 解决办法:执行命令：ln –sf /dev/fb/0 /dev/fb0，然后重启。

(3)编译错误:Qt/Embedded data directory is not owned by user 0:/tmp/qtembedded-0 解决办法：执行命令：chown root:root /tmp/qtembedded-0，然后重启。

二、因缺少类库或安装包不全出现编译错误的解决办法：
1.编译错误:
make[1]: Entering directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src'
g++  -c -I/usr/X11R6/include -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/include -I/usr/X11R6/include -pipe -O2 -Wall -W -DNO_DEBUG -fPIC -DQT_BUILTIN_GIF_READER=0 -DQT_NO_IMAGEIO_JPEG -DQT_NO_IMAGEIO_MNG -DQT_NO_SM_SUPPORT -DQT_NO_XKB  -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src/3rdparty/zlib -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src/3rdparty/libpng  -I3rdparty/kernel -I3rdparty/tools -o tmp/release-shared-linux-g++/3rdparty/kernel/qmotifdnd_x11.o 3rdparty/kernel/qmotifdnd_x11.cpp

make[1]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src'

原因:
缺少x11/xlib.h，安装libx11-dev即可解决：

解决办法：
zyx@zyx:~$ sudo apt-get install libx11-dev

2.编译错误:

make[1]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src'

原因:
缺少X11/extensions/shape.h，安装x11proto-xext-dev即可解决

解决办法:
zyx@zyx:~$ sudo apt-get install x11proto-xext-dev

3.编译错误:
make[1]: Entering directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/tools/designer/uic'

4.编译错误:

 done !
the konqueror directory is already !

原因：缺少luuid，安装uuid-dev即可解决

解决办法：
zyx@zyx:~$ sudo apt-get install uuid-dev

注：以下编译错误解决办法未验证。
6.编译错误：C compiler cannot create executables，
解决办法：sudo apt-get install gcc libc6-dev

7.编译错误：checking for C compiler default output... configure: error: C compiler cannot create executables
解决办法：sudo apt-get install libc6-dev

8.编译错误：configure: error: C++ preprocessor "/lib/cpp" fails sanity check
原因：gcc的组件没装全
解决办法：apt-get install build-essential

9.编译错误： Can't find X includes. Please check your installation and add the correct paths!
原因：没有X的包含文件
解决办法：安装xlibs-dev即可

10.编译错误： Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!
原因：查找提供qt的lib&&headers的软件包,并安装之
解决办法：apt-get install libqt3-headers libqt3-mt-dev

11.编译错误：in the prefix, you've chosen, are no KDE headers installed. This will fail.
So, check this please and use another prefix!
which basically means its going to want to install a lot of KDE specific packages to work. This 'configure:error'
is due to it expecting you to be running KDE and again refers to some 'headers'.

原因：install a KDE application in a Gnome environment。

解决办法：
sudo apt-get update
sudo apt-get install kdelibs4-dev kdelibs4c2a

12.编译错误：./admin/cvs.sh: 585: autoconf: not found
解决办法：apt-get install autoconf

13.编译错误： *** GTK >= 2.4.0 not installed! ***
原因：没装GTK
解决办法：apt-get build-dep gedit

14.编译错误：heching for gtk-config... no
checking for GTK - version = 1.2.0... no
*** The gtk-config script installed by GTK could not be found
*** If GTK was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the GTK_CONFIG enviroment variable to the
*** full path to gtk-config.
configure: error: Cannot find GTK: Is gtk-config in path?
解决办法：sudo apt-get install libgtk1.2-dev
15.编译问题：eclipse中encoding不支持中文
解决办法：编辑/var/lib/locales/supported.d/local，加一行zh_CN.GBK GBK，执行sudo locale-gen

16.编译办法错误：gnome.h: No such file or directory No package 'libpanelapplet-2.0' found
解决：sudo apt-get install gnome-panel

17.编译问题：eva不弹出输入法
解决办法：sudo apt-get install scim-qtimm

18.编译问题：
No package 'gtk+-2.0' found
No package 'gtksourceview-1.0' found
No package 'libgnomeui-2.0' found
No package 'libglade-2.0' found
No package 'libgnomeprintui-2.2' found

解决办法：sudo apt-get install libgtk2.0-dev libgtksourceview-dev libgnomeui-dev libglade2-dev libgnomeprint2.2-dev

19.编译问题：No package 'libpanelapplet-2.0' found
解决办法：sudo apt-get install libpanelappletmm-2.6-dev

三、源代码问题函数错误及权限不足出现编译错误的解决办法：
1.编译错误:

make[5]: *** [.obj/release-shared/vobject.o] Error 1
make[5]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/src/libraries/qtopia'

原因:函数返回值类型不匹配

解决方法：
修改/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/src/libraries/qtopia/backend/vobject.cpp:第419行
将
   char *dot = strrchr(g,'.');
修改为
   char *dot = (char*)strrchr(g,'.');
4.编译错误:

make[6]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/src/plugins/codecs/wavplugin'

原因:函数返回值类型不匹配

解决方法：
修改/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/src/plugins/codecs/wavplugin/wavplugin.cpp:第435行
将
    char *ext = strrchr( path.latin1(), '.' );
修改为
    char *ext = (char*)strrchr( path.latin1(), '.' );

5.编译错误(此为arm编译脚本运行时出现的错误):
In function ‘open’,
    inlined from ‘main’ at ts_calibrate.c:230:
/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
In function ‘open’,
    inlined from ‘main’ at ts_calibrate.c:232:
/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

原因:
在Ubuntu 10.10上， gcc会严格检查open()的参数传递，如果第二个参数为O_CREAT的话，必须传入第三个参数mode来提供创建权限。

解决方法：
确定ts_calibrate.c的位置：
root@zyx:/opt/EmbedSky/Qte# locate ts_calibrate.c
/opt/EmbedSky/Qte/arm-qtopia-2.2.0/tslib-1.4.1/tests/ts_calibrate.c

修改/opt/EmbedSky/Qte/arm-qtopia-2.2.0/tslib-1.4.1/tests/ts_calibrate.c:第230行
将
   cal_fd = open (calfile, O_CREAT | O_RDWR);
修改为
   cal_fd = open (calfile, O_CREAT | O_RDWR,0666);

修改/opt/EmbedSky/Qte/arm-qtopia-2.2.0/tslib-1.4.1/tests/ts_calibrate.c:第232行
将
   cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR);
修改为
   cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR,0666);
