Ubuntu :: Skype: Symbol Lookup Error: /usr/lib32/libQtDBus.so.4: Undefined Symbol
Jan 17, 2010ive made a slight mistake on my Ubuntu 9.10 64bit. I was trying to get Voodoo Motion Tracking software to work, and it was having trouble locating some Qt Libs, so I decided it was a good idea to move its included libs into /user/lib32 directory. Voodoo now works, but Skype instead comes up with:
Code:

Ubuntu Installation :: Symbol Lookup Error: /usr/lib/libnssutil3.so.1d: Undefined Symbol: PL_ClearArenaPool

/usr/lib/thunderbird-3.0.3pre/thunderbird-bin: symbol lookup error: /usr/lib/libnssutil3.so.1d: undefined symbol: PL_ClearArenaPool
I can only assume the libnssutil3 library was upgraded and this broke the library call in the thunderbird-3.0.

Networking :: PING - Pipe 2 Versus Pipe 3
Apr 10, 2009I'm doing ping between 2 RH servers through a VPN site2site tunnel and in some times I got in the result pipe 2 and another pipe 3 as I mark it in blue color below.
e.g.
64 bytes from 192.168.1.10: icmp_seq=0 ttl=128 time=0.229 ms
64 bytes from 192.168.1.10: icmp_seq=1 ttl=128 time=0.287 ms
64 bytes from 192.168.1.10: icmp_seq=2 ttl=128 time=0.278 ms

What's the difference between pipe 2 and pipe 3 and what's the meaning of it?
Debian Multimedia :: Pidgin: Symbol Lookup Error: Pidgin: Undefined Symbol: Purple_media_element_info_get_type
Aug 1, 2010Previously after doing aptitude upgrade, my pidgin seems broken with no gui shown. So I decided to download the latest source from pidgin website and build it from source, but I think I made situation worse because it then complained that ssl lib was needed. Then I removed the libpurple (e.g. aptitude purge libpurple0 libpurple-bin libpurple-dev) and reinstalled pidgin (aptitude install pidgin). Now it shows the error
pidgin: symbol lookup error: pidgin: undefined symbol: purple_media_element_info_get_type
I searched on the internet and can not find a solution. The clues on the internet says that's because the piding I use is the older version of libpurple. But I think I've removed all with purge and reinstalled it. Maybe some legacy binary is referenced. What or where it might be? Or where there may contain related information.

I'm following the instructions for troubleshooting here but the pipe "|" key is not working - a tilda "~" shows up when I press it.I'm wondering if this is because of the keyboard being set as UK instead of US? I did have to change this setting at the graphical login initally, whether from choosing this setting by mistake or the installer choosing it automatically when I chose English UK for the language.

General :: Understanding How Pipe Works In Bash
Aug 21, 2010I don't quite understand how pipes work in bash. I know that it takes an output from one command as the input in another command. What an output is I can get because it's what the command prints out to the screen. But how do I know what input a command will take? Here is an example I thought would work:
Which gem | rm
Unfortunately it didn't.
Which gem prints out "/usr/bin/gem" so that must be the output right? I thought that was given to rm so it would be "rm /usr/bin/gem" but I was wrong. How do I know what input a command takes?

Jul 25, 2010Two processes are communicating through a pipe: A | B. A is writing data faster than B is reading it in. Is there any way to have A limit its writing rate to match B's reading rate?
AFAIK the pipe will get full, and will make A's writing block, waiting for B to read in more data. But is there a way to limit A's writing rate before the pipe fills up? (In a way it's like having a pipe with a really small capacity, but as far as I know pipe capacity is a constant compiled into the kernel.)
Code:
EXAMPLE FOR CLARIFICATION
Right now the command is printing out the following in 1-second intervals:
But with flow control it should print out (again in 1-second intervals):
...since "date" would block on the writing loop due to the slow reading loop.

General :: Pipe Kernel Messages To Another Process As They Occur
Apr 13, 2011I have an OLED screen on my laptop that I have configured to show status information. The current driver I have installed in Linux for it is able to display messages by sending them to a script as an argument separated by spaces.Example: the command /opt/asusg50oled/utils/notify.sh Hi Everybody "Hello World" displays on the oled screen:
Hi
Everybody
Hello World
If another message is sent before the old ones disappear and it reverts to status info, it pushes off the top message. Example: less than 30 seconds after the previous example, /opt/asusg50oled/utils/notify.sh "Bananas have potassium" is executed:
Everybody
Hello World
Bananas have potassium
What I want to do is have kernel messages (the kind you see by running dmesg) forwarded to this script. For example, when I insert a USB drive, the following information would show on the OLED screen as they're logged:........
