在fedora15上编译pc版的qtopia2.2所遇到的问题

在fedora15下编译qtopia问题,遇到了很多问题，都无法解决，感觉很无赖。经过不断的google收集,这些问题得到了解决
首先要 vim build
cd qtopia-2.2.0-FriendlyARM

echo yes | ./configure -qte '-embedded -no-xft -qconfig qpe -depths 16,32 -system-jpeg -gif' -qpe '-edition pda -displaysize 240x320  -fontfamilies "helvetica fixed micro smallsmooth smoothtimes"' -qt2 '-no-opengl -no-xft' -dqt '-no-xft -thread'

make
make install
cd ..

#/bin/rm qtopia-2.2.0-FriendlyARM/qtopia/image/opt/Qtopia/lib/fonts/helvetica_*
mkdir  qtopia-2.2.0-FriendlyARM/qtopia/image
tar xfvz fonts.tar.gz -C qtopia-2.2.0-FriendlyARM/qtopia/image

  错误1：
    backend/vobject.cpp: In function ‘VObject* addGroup(VObject*, const char*)’:
     backend/vobject.cpp:419: error: invalid conversion from ‘const char*’ to ‘char*’
修改/x86-qtopia-2.2.0/qtopia/src/libraries/qtopia/backend/vobject.cpp:419行
        char *dot = strrchr(g,'.');
为    char *dot = (char*)strrchr(g,'.');
  错误2：
videocaptureview.cpp:54:28: 致命错误： linux/videodev.h：没有那个文件或目录
编译中断。
make[6]: *** [.obj/release-shared/videocaptureview.o] 错误 1
解决方法
yum install libv4l-devel
ln -s /usr/include/libv4l1-videodev.h   /usr/include/linux/videodev.h
错误3：
../include/qvaluelist.h:88:13: error: ‘ptrdiff_t’ does not name a type
../include/qvaluelist.h:164:13: error: ‘ptrdiff_t’ does not name a type

                 from kernel/qwidget.h:43,
                 from kernel/qdesktopwidget.h:40,
                 from kernel/qapplication.h:42,
                 from kernel/qapplication_x11.cpp:64:

                 from kernel/qapplication.h:42,
                 from kernel/qapplication_x11.cpp:64:

                 from kernel/qapplication_x11.cpp:64:
../include/qmap.h:604:13: error: ‘ptrdiff_t’ does not name a type
解决方法
在qtopia-2.2.0-FriendlyARM/dqt/include/qvaluelist.h文件下增加两个头文件：#include "stddef.h"和#include <cstddef>
错误4：
wavplugin.cpp: In member function ‘virtual bool WavPlugin::isFileSupported(const QString&)’:
wavplugin.cpp:435:45: error: invalid conversion from ‘const char*’ to ‘char*’

修改

    char *ext = strrchr( path.latin1(), '.' );

为

    char *ext = (char*)strrchr( path.latin1(), '.' );
错误5：

       /usr/bin/ld: .obj/release-shared/transferserver.o: undefined reference to symbol 'crypt@@GLIBC_2.0'
       /usr/bin/ld: note: 'crypt@@GLIBC_2.0' is defined in DSO /lib/libcrypt.so.1 so try adding it to the linker command line

       这个找了好久发现用了crypt函数而没使用-lcrypt，   qtopia-2.2.0-FriendlyARM/qtopia/configure  1373行加入

       print CONFIG_PRI "LIBS+=-lcrypt\n";

错误6：
x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin/qpe: error while loading shared libraries: libqtopia2.so.2: cannot open shared object file: No such file or directory
解决方法:
cd x86-qtopia
mv  run qtopia-2.2.0-FriendlyARM/  下修改 run
vim run
qt2/bin/qvfb -width 480 -height 272 -depth 16 &
cd /qtopia/image
mkdir root 2>/dev/null || true
echo $PWD

export HOME=$PWD/root
#cd opt/Qtopia
#export PATH=$PWD/qtopia/bin:$PATH
export LD_LIBRARY_PATH=$PWD/qtopia/lib:$LD_LIBARAY_PATH
export QTDIR=$PWD/qt2
export QPEDIR=$PWD/qtopia
#export KDEDIR=$PWD/../kde

sleep 3
$PWD/qtopia/bin/qpe

再运行 run

错误7：
[root@localhome bin]# ./qpe
Cannot find font definition file /usr/lib/qt-3.3/lib/fonts/fontdir - is $QTDIR set correctly?

修改 /etc/profile
vim /etc/profile
QTDIR=x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2
PATH=$PATH:$QTDIR/bin
QT_QWS_FONTDIR=$QTDIR/lib/fonts
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/lib
export PATH  QTDIR  LD_LIBRARY_PATH QT_QWS_FONTDIR
然后
source /etc/profile
