Change remove (this-> fromlast (); to this-> remove (this-> fromlast ());

 

Error2: 'qwsinputmethod' has not been declared

Correction Method:

CD $ qtdir/src/kernel // $ dtdir =/home/opiehome/qt-2.3.10

Gedit qwindowsystem_qws.h

Add the following two lines

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/2410 clqt/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/2410 clqt/qt-2.3.10/bin/qvfb:/usr/lib/libstdc ++. so.5: Version 'glibcpp _ 3.2 'not found (required by/root/2410 clqt/qt-2.3.10/bin/qvfb)
/Root/2410 clqt/qt-2.3.10/bin/qvfb:/usr/lib/libstdc ++. so.5: Version 'cxxabi _ 1.2 'not found (required by/root/2410 clqt/qt-2.3.10/bin/qvfb)

So I download this low version:

Rm/usr/lib/libstdc ++. so.5

Then download: http://mirror.centos.org/centos/4/ OS /i386/CentOS/RPMS/compat-libstdc++-33-3.2.3-47.3.i386.rpm

Reinstall
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 ~ /2410 clqt
[Root @ localhost 2410 clqt] # export qtedir = $ PWD/qt-2.3.10
[Root @ localhost 2410 clqt] # 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

[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.

Error 2:

Qvaluestack. h: 57: Error: cannot be converted from 'qvaluelistiterator <qstring> 'to 'const char *'. It is an actual parameter '1' (belonging to 'int remove (const char *)')

Correction Method:

Gedit $ qtdir/include/qvaluestack. H &

Change remove (this-> fromlast (); to this-> remove (this-> fromlast ());

Make has the following problems during build qt2.3.2:

Methods for successful compilation:

Change the source code for src/tools/qvaluestack. h 57th lines in the qt-2.3.2 Folder:

Remove (this-> formlast ());

Is:

This-> remove (this-> formlast ());

Use the following statement when configuring configure:

./Configure-debug-no-OpenGL-no-xft

Q2: Make has the following problems during build QT/Embedded:

Error: 'qwsinputmethod' has not been declared

Correction Method:

CD $ qtdir/src/kernel // $ dtdir =/home/opiehome/qt-2.3.10

Gedit qwindowsystem_qws.h

 

Add the following two lines to the front:

 

Class qwsinputmethod;

Class qwsgesturemethod;

Q3: When NFS is used, an NFS error occurs when some files in the CP are larger:

NFS: Server *** not responding, still trying

Modification method:

NFS crashes during NFS mount. Mount the NFS as follows:
Mount-T nfs-O intr, nolock, rsize = 1024, wsize = 1024 192.168.1.3/root/somedir/Host

Q4: During the test, "./progressbar-qws" prompts the same as Q3, which should be handled by Q3.

Next:

/Home/work/armqt/qtlibsource/temp/qt-2.3.7/include/qsortedlist. h: 51: Error: 'clear' real parameters do not depend on template parameters, so 'clear' Declaration must be available

/Home/work/armqt/qtlibsource/temp/qt-2.3.7/include/qsortedlist. h: 51: Error: (if you use '-fpermission', G ++ will accept your code, but the undefined name is allowed to be outdated)

Solution:

VI Include/qsortedlist. h

The row 51st is modified as follows:

~ Qsortedlist () {clear ();} -- à ~ Qsortedlist () {This-> clear ();}

 

 

Next: the error is returned here.
Kernel/qwindowsystem_qws.cpp: 1810: Error: Comparison between distinct pointer types 'qwsserver: wsinputmethod * 'and 'qwsinputmethod *' lacks a cast
Kernel/qwindowsystem_qws.cpp: 1812: Error: cannot convert 'qwsserver: wsinputmethod * 'to 'qwsinputmethod *' in assignment

Static qwsinputmethod * current_im = 0; // current_im Definition

Void qwsserver: setcurrentinputmethod (qwsinputmethod * IM)
{
If (current_im_state! = Imend & (qwsinputmethod *) Im! = Current_im & qwsserver) // 1810 rows
Qwsserver-> sendimevent (imend, "",-1, 0 );
Current_im = (qwsinputmethod *) im; // 1812 rows
}

I think it should be a C ++ syntax problem. I cannot convert the (qwsinputmethod *) method to the IM type. How can I modify it? No one has ever met it?
