Anyone got RealVNC 4.0 (beta) working?

I'm desparately trying to install RealVNC 4.0 b4. I've downloaded the binaries from realvnc, have run the vncinstall script. At first I was getting an error trying to run vncconfig (new to RealVNC 4.0),

Code:

vncconfig: error while loading shared libraries: libXaw.so.6: cannot open shared object file: No such file or directory

and I think (going by the VNC log files) that I was starting the old version of VNC... So I uninstalled (via apt-get) the old version. Now I cannot even start RealVNC:

Code:

christopher@roro:~$ vncserver New 'roro:1 (christopher)' desktop is roro:1 Starting applications specified in /home/christopher/.vnc/xstartup Log file is /home/christopher/.vnc/roro:1.log christopher@roro:~$ cat /home/christopher/.vnc/roro:1.log Xvnc: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory xsetroot: unable to open display 'roro:1' vncconfig: error while loading shared libraries: libXaw.so.6: cannot open shared object file: No such file or directory twm: unable to open display "roro:1" xterm Xt error: Can't open display: roro:1

I've tried creating a symlink for libstdc++-libc6.1-1.so.2, have tried to find an updated package, have googled a a lot but still no joy. So,
1. has anyone got RealVNC 4.0 running on a Knoppix install?
2. any idea on how I can solve my missing 'shared object file'(s) problem?

Cheers

p.s. I want to use RealVNC 4 and not the VNC that comes with Knoppix so that I can share my display :0.

1. I've got RealVNC 4.0b4 working, but I haven't managed to share the desktop (:0).

Code:

christopher@roro:~$ vncviewer localhost:0 VNC viewer for X version 4.0b4 - built Sep 4 2003 13:31:22 Copyright (C) 2002-2003 RealVNC Ltd. See http://www.realvnc.com for information on VNC.

As for 2., I find I had a more recent version of the library and learnt :) how to create a symlink

Code:

christopher@roro:/usr/lib$ ls | grep "libstdc" libstdc++-3-libc6.2-2-2.10.0.so libstdc++-libc6.2-2.so.3 libstdc++.so.5 libstdc++.so.5.0.5 christopher@roro:/usr/lib$ ln -s libstdc++-libc6.2-2.so.3 libstdc++-libc6.1-1.so.2 ln: creating symbolic link `libstdc++-libc6.1-1.so.2' to `libstdc++-libc6.2-2.so.3': Permission denied christopher@roro:/usr/lib$ su Password: root@roro:/usr/lib# ln -s libstdc++-libc6.2-2.so.3 libstdc++-libc6.1-1.so.2 root@roro:/usr/lib# exit

I use both VNCserver and VNCviewer on my knoppix install and have had no problems sharing desktop:0

IF you are having problems from the commandline, try the gui

Go to the Control Centre and click on "Internet and Network"
Click on "Desktop Sharing"
Tick, "Allow uninvited connections"
Tick, "Allow uninvited connections to control the desktop"
Set a password
Apply

Thats it.

If it is so desperate I would just use an older version and not worry about it.

Hi, I have the same problem, my OS is Fedora.I had vnc-server-4.0-0.beta4.3.2 installed.
When I run vncviewer:
vncviewer: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory
I search for libstdc++
[root@localhost lib]# ls -la libstdc++*
lrwxrwxrwx 1 root root 18 Apr 10 16:57 libstdc++.so.5 -> libstdc++.so.5.0.5
-rwxr-xr-x 1 root root 739636 Oct 24 02:26 libstdc++.so.5.0.5

Could anyone help me, how do I create a link here??
Thanx for your help!

I got the answer on the RealVNC mailing list about ten days ago, but didn't have time to post back here... I had to add an an 'option' line to the 'options ' section of XF86Config-4 file, e.g.

Code:

Option "passwordFile" "/root/.vnc/passwd"

@new2unix
You are using KDesktop Sharing, which is based on VNC but is not VNC. As I said, that did not work on my system (I upgraded to KDE 3.2.1 and something broke, which means desktop sharing no longer worked; it's reportedly fixed in 3.2.2).

@ExtremeHobo
Because as I explained very few flavours of VNC can share display :0 (the current desktop). K Dsktop Sharing can (but it's broken in 3.2.1), RealVNC 4.0 can, all other versions of VNC cannot. (AFAIK)

@redsun
looks like you're lacking the library; I imagine you need to grab an RPM from somewhere (shame you can't use apt-get ;). Googling 'rpm libstdc++-libc6.1-1' looked promising.

BTW RealVNC 4.0b4 is great, I can graphically access my Knoppix box any time after boot now :), I can even get the KDM login screen!

works

the vnc server works on the main hd install

you can remotly launch it by ssh

/usr/bin/vncserver

then launch the viewer on the local comp - (my is on win2K)

but i couldn't get the viewer work on knoppix to access my win comp

yep, but then you create a new desktop - the idea is to share the 'native' desktop, the one you see on the knoppix box itself

no problems here - I can see my linux desktop from my XP notebook, I can also do the inverse (which is even easier).

Anyway, as I wrote earlier, everything (well, VNC-wise) is now working properly :)

Enter your ip address with a :1 in the VNC server location, it will let you connect to a seperate desktop but like what was said it won't be the native desktop, which is ok for some things. I use it to admin my game servers at lan parties to I don't need an extra monitor for the server.

As for the native desktop i'm still working on that too.
