[raman_31181]

Hello,
I have been working on Qt4 Designer for some days now.Today I encountered a strange problem.The Qt Designer window just doesnt appear when I try to open this tool.I tried through KMenu->Development->Qt4 Designer but the result is the same.I tried through Konsole and get the follwoing error:

[root@localhost mywidgetplugin]# designer-qt4
/usr/lib/qt4/bin/designer-qt4: error while loading shared libraries: libts-0.0.so.0: cannot open shared object file: No such file or directory

[root@localhost mywidgetplugin]# designer-qt4
/usr/lib/qt4/bin/designer-qt4: error while loading shared libraries: libts-0.0.so.0: cannot open shared object file: No such file or directory

Thanks jpn.....I had just tried reinstalling qt4-designer through
yum install qt4-designer
before I read your reply.Now when I try to open qt4-designer from the terminal through
designer-qt4.I get the follwoing error:

[root@localhost ~]# designer-qt4

add the "-qws" command-line option.

When I add -qws to the command this is what I get:

I have no idea how this tool which was working fine a week ago crashed all of a sudden...

Well, I wouldn't myself even bother using Qt Designer in frame buffer but use the X11 version of Qt Designer to design my forms.

[raman_31181]

Yeah in fact earlier I had been using X11 version......I guess I installed the wrong version this time......Do I need to delete any files before I reinstall qt4-designer using yum install?
Can anyone please list out the steps for reinstalling qt4-designer X11 version?
I tried with
yum install qt4-designer
but I am not able to use this installed version.Do I need to delete previous Qt4 files before reinstalling?
I already have Qtopiacore 4.3.3 installed on my system.

[raman_31181]

Anyone can help me out with installation on Qt4-Designer?I tried installing for the nth time using
yum install qt4-designer

but when I double click the shortcut the window just doesnt show up.

I tried opening from the terminal but I get this error

[root@localhost /]# designer-qt4
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused

I guess this is the framebuffer version but I need X11 version.I already have qtopia-4.3.3
installed on my sytem.Can anyone share any ideas?

[jpn]

'designer-qt4' is likely just a symbolic link. Find out where the actual binaries are and launch the X11 version instead of the framebuffer version.

[raman_31181]

I queried for file type of designer-qt4.is is a symbolic link to designer

All the binaries are located at /usr/lib/qt4/bin.
My question is how do I launch the X11 version instead of framebuffer version?
These are the contents of the location

[root@localhost bin]# pwd
/usr/lib/qt4/bin
[root@localhost bin]# ls
designer      lrelease      moc        qdbuscpp2xml  qmake-qt4  uic3
designer-qt4  lrelease-qt4  moc-qt4    qdbusviewer   qt3to4     uic-qt4
linguist      lupdate       pixeltool  qdbusxml2cpp  rcc
linguist-qt4  lupdate-qt4   qdbus      qmake         uic
[root@localhost bin]#

[root@localhost bin]# pwd
/usr/lib/qt4/bin
[root@localhost bin]# ls
designer      lrelease      moc        qdbuscpp2xml  qmake-qt4  uic3
designer-qt4  lrelease-qt4  moc-qt4    qdbusviewer   qt3to4     uic-qt4

Where does "yum install qt4-designer" install the designer binary? Where did you install qtopia-4.3.3?

[raman_31181]

qt4-designer binaries installed at
/usr/lib/qt4/bin

qtopia-4.3.3 was installed at
/usr/local/Trolltech/QtopiaCore-4.3.3/

[jpn]

qt4-designer binaries installed at
/usr/lib/qt4/bin

qtopia-4.3.3 was installed at
/usr/local/Trolltech/QtopiaCore-4.3.3/

Do you have /usr/local/Trolltech/QtopiaCore-4.3.3/bin in PATH? What if you launch /usr/lib/qt4/bin/designer (without -qt4 suffix).

[raman_31181]

I have this added in /etc/profile file

PATH=/usr/local/Trolltech/QtopiaCore-4.3.3/bin:$PATH
export PATH

So I think the PATH is set.Besides I have developed some applications using qtopia.

when I launch /usr/lib/qt4/bin/designer from the terminal I get this:

[root@localhost /]# /usr/lib/qt4/bin/designer
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused

Thanks,

Well, somehow you have managed to put the designer binary of QtopiaCore-4.3.3 to /usr/lib/qt4/bin/. Did you copy files by hand? What does 'ldd /usr/lib/qt4/bin/designer' output?

[raman_31181]

running ldd give this

[root@localhost /]# ldd /usr/lib/qt4/bin/designer
/usr/local/arm/3.3.2/bin/ldd: line 130: /usr/local/arm/3.3.2/lib/ld-linux.so.2: cannot execute binary file
/usr/local/arm/3.3.2/bin/ldd: line 140: /usr/local/arm/3.3.2/lib/ld-linux.so.2: cannot execute binary file
ldd: /usr/local/arm/3.3.2/lib/ld-linux.so.2 exited with unknown exit code (126)

I have designer binary in /usr/local/Trolltech/QtopiaCore-4.3.3/bin.I have posted the contents:

[root@localhost bin]# cd /usr/local/Trolltech/QtopiaCore-4.3.3/bin
[root@localhost bin]# ls
assistant lupdate.debug qdbusviewer rcc
assistant.debug moc qdbusviewer.debug rcc.debug
designer moc.debug qdbusxml2cpp uic

linguist pixeltool.debug qmake uic3.debug
linguist.debug qdbus qt3to4 uic.debug
lrelease qdbuscpp2xml qt3to4.debug
lrelease.debug qdbuscpp2xml.debug qtdemo
lupdate qdbus.debug qtdemo.debug
[root@localhost bin]#

I did not copy any binaries./usr/lib/qt4 folder was created as a result of
yum install qt4-designer
command.

[raman_31181]

Just to confirm whether designer binaries of qt4 and qtopia are conflicting with each other or not I uninstalled qt4 through

yum remove qt4-designer

and tried this from the command line

[root@localhost /]# /usr/local/Trolltech/QtopiaCore-4.3.3/bin/designer
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused
QWSSocket::connectToLocalFile could not connect:: Connection refused

which doesnt seem to work anyway.Any ideas?Is there any other way to install qt4-designer?

[raman_31181]

Can anyone help me out with this?I am lost......

[raman_31181]

Finally this is solved....
i carried out
yum install qt-designer

This installed 3 packages

================================================== ===========================
Package Arch Version Repository Size
================================================== ===========================
Updating:
qt-designer i386 1:3.3.8-2.fc6 updates 1.9 M
Updating for dependencies:
qt i386 1:3.3.8-2.fc6 updates 3.5 M
qt-devel i386 1:3.3.8-2.fc6 updates 4.6 M

After the installation was complete qt4 designer started working again!!!!! I think it needed some dependencies, qt-devel may be....
