I am trying to install an Open GL screen saver "EulerTop-1.2" and I get the following error message when I run configure - "checking for perl /usr/bin/perl checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. For more details about this problem, look at the end of config.log. Make sure that you have compiled Qt with thread support!" It appears to be installed -
Anyone know of a good download manager for ubuntu that will support multi thread as well as site logins. I do a lot of downloading from rapid share and all the download managers i've tried don't support site logins.
A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit
I am going to use "pthread_setaffinity_np" to bind a thread to a specific core. My application has two threads. I have used mutex to assign a specific id to each thread and then bind that thread to a core different from another core. but it seems that the os assigns both thread to one core.What should I do to bind each thread to a specific core?
A while back I compiled a custom kernel, 2.6.35. I forgot to add UDF support when configuring and compiling. Will I need to re-compile the kernel to get UDF support or is there some other way I can add it?
I've successfully compiled and installed PHP to run with nginx. But I could not use some jpeg functions from GD library. I've checked for libjpeg-devel and gd-devel and found that they had been installed, libjpeg.so is located at /usr/lib This is my configure command:
I have trouble compiling FFMPEG with VDPAU support. I have clean typical installation Fedora 14 + all updates and after installation I install Nvidia driver with VDPAU support - kmod (VPDAU works well, tested with mplayer - I play MKV 1080p on Atom D525 + chipset Nvidia ION with 10-15% CPU ussage). I try compilie FFMPEG with this procedure:
A friendly "HELLO WORLD!" from my side first I've got a problem compiling the current ALSA-Drivers (1.0.22.1) for my Scientific Linux name -a inux comp_854 2.6.18-164.11.1.el5 #1 SMP Wed Jan 20 00:57:09 EST 2010 x86_64 x86_64 x86_64 GNU/Linux

The sysytem I use is Debian Squeeze. what's wrong but jackd2 from debian official repositories does not work with alsa (I have alsa-base, alsa-tools, libaudio-dev, libaudiofile-dev and libasound2-dev installed). Now I downloaded fresh jackd2 source from sourceforge and when I try to "./waf -configure" it it says that there is no alsa package or it's too old in the system and configures itself without alsa support.
One of those odd things I learned the hard way is that if you are writing a shared object (library/.so) and any programs that will link to that library uses floating point numbers, the library must be compiled as if it uses floating point numbers. What that really means is, you need to declare at least one float in the source for the library or when the caller connects and tries to run code in the library, the process aborts.I end up putting a float pi (3.1415); in the code and getting an unused variable warning all the time. There has to be a simpler way, some flag to pass to g++ that says, "include floating point support even if you don't really need to."
p.s. Gosh I hope I remembered this correctly. I encountered this problem doing a multi-platform build for Windows and Linux. This COULD be a VC++ problem that I just carried into Linux by using the same source.

I'm a Windows admin who does part time Linux server installs. Most of the time I'm asked to deploy a generic Windows server, install a few basic applications and if needed some other applications like Nagios or Zabbix. My question is for long term support, or patching should I be focusing on deploying with repositories to install applications or compile from source? In the Windows world you can patch and update from Windows Update, but is there problems using 3rd party repositories for future updates? Would one of these locations go off line?
Same problem as someone else below- my optical drive will not read CDs in SuSE 11.3 (all the latest patches). CDs read fine in Windows, DVDs fine in both.This is a brand new drive, since my old one gave up the ghost last Tuesday (no longer appeared in BIOS)Drive is Samsung SH-S223L, and dmesg gives the following errors:

I went through really a lot of Linux systems, and I think I am going to settle on Opensuse OS. I must say Opensuse 11.3 is fantastic! However I have this lousy in the top 5 of evil graphic cards list ATI Radeon XPRESS 200 card. This version of Opensuse seems to best realize what creature it is and gives the biggest description of it in the hardware information from all Linux distros I have tried. Unfortunately I have a big trouble to install proprietary drivers. I downloaded the recommended drives from amd-ati homepage but on debian and ubuntu installing via terminal simply reports an error while Opensuse doens;t even try to run the ati run file of drivers.
Could somebody please assist me and give recommendations what to do in order to install proprietary legacy drivers? Keep in mind I am a complete newbie. The only thing I am good at with terminal is copy/paste. I learned how to add repos to the yeast and successfully added amd ati repo to the lsit, but it still doens;t seem to give anything suitable in my case.
I do believe it would be a valuable source for people looking for steps instruction related to legacy drivers so lets consider this something like How To Escape ATI Legacy Drivers Nightmares thread.
Not sure if I have landed in right place for this question .Problem FacedI have 30-40 heavy load (Memory operations on heap) processor running with each having 30-40 threads.In one of the thread (of each process), I have file locking operation as explained below (say in thread T1)Step 1 - Lock the file using fcntl(SETWLK) on file f1, Basically using wait lock.Step 2 - Read/write data from another file f2.Step 3 - unlock the file f1.As the memory occupied by process increased, the swap area used will reduce - this continues for a long amount of period. When the free swap space is reduced to 100 MB free out of 2 G and VIRT reduces to 120MB free out of 17G, for T1 thread, Step 3 is not scheduled for more than 300 seconds after Step 1 and 2.
I want to understand why this behavior is present - as per my understanding scheduling will occur within micro-seconds and we can expect that the T1 thread of all process should be scheduled without too much delay.Additional InfomationMachine Info : (uname -a), Linux linux 2.6.16.46-0.12-smp#1 SMP Thu May 17 14:00:09 UTC 2007 x86_64 x86_64 GNU/LinuxMemory Info :Total Memory is 16GB + Swap Memory is 2GBI want to know why this behavior is observed in SUSE
This thread (nxserver now broken?) has inspired me to install FreeNX and the client from nomachine on openSUSE-11.2 (this is the version used on both, server and client machine). The good news is: basically it works. I can connect and get the desktop. However, I have some trouble with the keyboard. Up and Down arrow keys do not work. The up arrow triggers a screen snapshot. The down arrow key does nothing. I tried to connect using qtnx as well. This does not work. Result is:

I was using my college's unix server (ubuntu presumably) to compile programs in the laboratory. Now, i have installed Opensuse 11.4 with gnome3. I have installed the Developers pattern, and almost all the packages that looked relevant (which came up when i searched for libgc , gcc, and all). Now, i cant compile a program:
Code: /*program to test file I/O and getch/putch functionaliny in gcc*/ #include<stdio.h> int main() { FILE *fi; char ch;
I was wondering - is there any multi touch gesture support in openSuse 11.4? I have enabled multi touch scrolling under the 'Mouse' module in Yast, and it works fine. However, i was wondering if a multi touch gesture set is available - such as pinch zoom, or even custom gestures mapped to keyboard combos - e.g. using a spiral to launch terminal?

I can compile and run ntpd 4.2.6p2, but after a while the reach indicator falls back from 377 to 0 and then the ntpd is in an unsynced state for a while. So far I haven't seen any indication why we have this.
I just tried to install qtparted ver0.4.5 on my computer to help partitioning my HDs.After doing the "configure/make"-sequence (using unsermake, as required), I received following error during compilation: "qp_libparted.cpp:1751: error: �ped_free� was not declared in scope",My parted version is 1.9.0-3.7.1 from openSuSE 11.2.My question:
1. Do you know, which other library might contain this "ped_free"-declaration? 2. Any other perted GUI, that might work better (gparted is only available on a live DVD after boot)
