Qt/QTE 编译安装问题与解决方法

编译Qt/Embedded

编译过程出现错误：

error 1

/root/2410clQt/qt-2.3.2/include/qvaluestack.h:57: 错误：不能将‘int remove(const char*)’的实参‘1’从‘QValueListIterator<QMap<QString, QString> >’转换到‘const char*’

make[1]: Leaving directory `/root/2410clQt/qt-2.3.2'
make: *** [init] 错误 2

solving :

gedit $QTDIR/include/qvaluestack.h &

将remove( this->fromLast() );改为this->remove( this->fromLast() );

error2: ‘QWSInputMethod’ has not been declared

修正方法：

cd $QTDIR/src/kernel //$DTDIR=/home/opiehome/qt-2.3.10

gedit qwindowsystem_qws.h

在前面增加以下两行

class QWSInputMethod;

class QWSGestureMethod;

P143

while trying the forth step:

export QTDIR=$QTEDIR
export PATH=$QTEDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTEDIR/lib:$QT2DIR/lib:$LD_LIBRARY_PATH

[root@localhost launcher]# $QTEDIR/bin/qvfb -width 640 -height 480
/root/2410clQt/qt-2.3.10/bin/qvfb: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

then:
I try:

[root@localhost lib]# pwd

/usr/lib
[root@localhost lib]# ls libstdc++.so*
libstdc++.so.6 libstdc++.so.6.0.10

there is no libstdc++.so.5:

so i try to create a link

[root@localhost lib]# ln -s libstdc++.so.6 libstdc++.so.5

but new problem exist;
[root@localhost launcher]# $QTEDIR/bin/qvfb -width 640 -height 480
/root/2410clQt/qt-2.3.10/bin/qvfb: /usr/lib/libstdc++.so.5: version `GLIBCPP_3.2' not found (required by /root/2410clQt/qt-2.3.10/bin/qvfb)
/root/2410clQt/qt-2.3.10/bin/qvfb: /usr/lib/libstdc++.so.5: version `CXXABI_1.2' not found (required by /root/2410clQt/qt-2.3.10/bin/qvfb)

so i download this low version:

rm /usr/lib/libstdc++.so.5 然后下载：http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/compat-libstdc++-33-3.2.3-47.3.i386.rpm 再安装 rpm -ivh compat-libstdc++-33-3.2.3-47.3.i386.rpm

result:

[root@localhost lib]# ls libstdc++.so*
libstdc++.so.5.0.7 libstdc++.so.6 libstdc++.so.6.0.10
[root@localhost lib]# ln -s libstdc++.so.5.0.7 libstdc++.so.5
[root@localhost lib]#

now

[root@localhost launcher]# $QTEDIR/bin/qvfb -width 640 -height 480

OK, virtual frambuffer start successfully

then , i open a new shell window.
and try to start a example program

[root@localhost john]# cd ~/2410clQt
[root@localhost 2410clQt]# export QTEDIR=$PWD/qt-2.3.10
[root@localhost 2410clQt]# cd $QTEDIR/examples/launcher
[root@localhost launcher]# ./launcher -qws
Cannot find font definition file /lib/fonts/fontdir - is $QTDIR set correctly?
[root@localhost launcher]#

now try to solving this new problem by

[root@localhost launcher]# export QTDIR=$QTEDIR
[root@localhost launcher]# export PATH=$QTEDIR/bin:$PATH
[root@localhost launcher]# export LD_LIBRARY_PATH=$QTEDIR/lib:$QT2DIR/lib:$LD_LIBRARY_PATH
[root@localhost launcher]# ./launcher -qws

libpng error: Valid palette required for paletted images

[root@localhost launcher]#

it works correctly ,
but still have an error.

maybe, following link is associated with this problem , but now ,i am too tired to continue my work today.

错误二：

qvaluestack.h:57: 错误：不能从 ‘QValueListIterator<QString>’ 转换到 ‘const char*’，为实参 ‘1’(属于 ‘int remove(const char*)’)

修正方法：

gedit $QTDIR/include/qvaluestack.h &

将remove( this->fromLast() );改为this->remove( this->fromLast() );

在Build Qt2.3.2时make出现如下问题：

xml/qxml.h:214: 警告：‘class QXmlReader’ 有虚函数却没有虚析构函数
xml/qxml.h:402: 警告：‘class QXmlContentHandler’ 有虚函数却没有虚析构函数

make[1]: *** [sub-src] 错误 2
make[1]: Leaving directory `/qt/qtx11'
make: *** [init] 错误 2

成功编译的方法：

更改qt-2.3.2文件夹中src/tools/qvaluestack.h第57行源代码：

remove (this->formLast() );

为：

this->remove (this->formLast() );

configure时要使用以下语句：

./configure -debug -no-opengl -no-xft

Q2：在Build Qt/Embedded时make出现以下问题：

error: ‘QWSInputMethod’ has not been declared

修正方法：

cd $QTDIR/src/kernel //$DTDIR=/home/opiehome/qt-2.3.10

gedit qwindowsystem_qws.h

在前面增加以下两行：

class QWSInputMethod;

class QWSGestureMethod;

Q3：使用nfs时在cp一些大点的文件时，出现NFS的错误：

nfs: server *** not responding, still trying

修改方法：

nfs mount时候出现的NFS崩溃，按照以下的方式mount
mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.1.3/root/somedir /host

Q4：在测试时，“./progressbar -qws”后出现如Q3一样的提示 ，按Q3来处理。
