  • Using Boost on ubuntu

    - by Dexter
    I've heard a lot of good comments about Boost in the past and thought I would give it a try. So I downloaded all the required packages from the package manager in Ubuntu 9.04. Now I'm having trouble finding out how to actually use the darn libraries. Does anyone know of a good tutorial on Boost that goes all the way from Hello World to Advanced Topics, and also covers how to compile programs using g++ on ubuntu?

  • How to compile a Windows binary in Ubuntu?

    - by George Edison
    I have a Qt application that I can compile in Ubuntu 10.04 64-bit and on Windows. However, I would like to avoid switching to Windows every time I want to compile the Windows version. Is there a way I can compile a Windows Qt executable in Ubuntu with mingw32 or something? Further, is there a way to integrate that compiler into Qt Creator?

  • Creating a Custom Ubuntu Daemon

    - by Chris S
    What's the "correct" way to create a custom daemon in Ubuntu, that will start at boot time and be controllable by Ubuntu's standard daemon start/stop commands? Can I just copy and paste one of the scripts in /etc/init.d or do I need to "register" the daemon somewhere else?

  • cannot make ubuntu 64-bit v12.04 install work

    - by honestann
    I decided it was time to update my ubuntu (single boot) computer from 64-bit v10.04 to 64-bit v12.04. Unfortunately, for some reason (or reasons) I just can't make it work. Note that I am attempting a fresh install of 64-bit v12.04 onto a new 3TB hard disk, not an upgrade of the 1TB hard disk that contains my working 64-bit v10.04 installation. To perform the attempted install of v12.04 I unplug the SATA cable from the 1TB drive and plug it into the 3TB drive (to avoid risking damage to my working v10.04 installation). I downloaded the ubuntu 64-bit v12.04 install DVD ISO file (~1.6 GB) from the ubuntu releases webpage and burned it onto a DVD. I have downloaded the DVD ISO file 3 times and burned 3 of these installation DVDs (twice with v10.04 and once with my winxp64 system), but none of them work. I run the "check disk" on the DVDs at the beginning of the installation process to assure the DVD is valid. When installation completes and the system boots the 3TB drive, it reports "unknown filesystem". After installation on the 250GB drives, the system boots up fine. During every install I plug the same SATA cable (sda) into only one disk drive (the 3TB or one of the 250GB drives) and leave the other disk drives unconnected (for simplicity). It is my understanding that 64-bit ubuntu (and 64-bit linux in general) has no problem with 3TB disk drives. In the BIOS I have tried having EFI set to "enabled" and "auto" with no apparent difference (no success). I never bothered setting the BIOS to "non-EFI". I have tried partitioning the drive in a few ways to see if that makes a difference, but so far it has not mattered. Typically I manually create partitions something like this: 8GB /boot ext4 8GB swap 3TB / ext4 But I've also tried the following, just in case it matters: 8GB boot efi 8GB swap 8GB /boot ext4 3TB / ext4 Note: In the partition dialog I specify bootup on the same drive I am partitioning and installing ubuntu v12.04 onto. It is a VERY DANGEROUS FACT that the default for this always comes up with the wrong drive (some other drive, generally the external drive). Unless I'm stupid or misunderstanding something, this is very wrong and very dangerous default behavior. Note: If I connect the SATA cable to the 1TB drive that has been my ubuntu 64-bit v10.04 system drive for the past 2 years, it boots up and runs fine. I guess there must be a log file somewhere, and maybe it gives some hints as to what the problem is. I should be able to boot off the 1TB drive with the 3TB drive connected as a secondary (non-boot) drive and get the log file, assuming there is one and someone tells me the name (and where to find it if the name is very generic). After installation on the 3TB drive completes and the system reboots, the following prints out on a black screen: Loading Operating System ... Boot from CD/DVD : Boot from CD/DVD : error: unknown filesystem grub rescue> Note: I have two DVD burners in the system, hence the duplicate line above. Note: I install and boot 64-bit ubuntu v12.04 on both of my 250GB in this same system, but still cannot make the 3TB drive boot. Sigh. Any ideas? ========== motherboard == gigabyte 990FXA-UD7 CPU == AMD FX-8150 8-core bulldozer @ 3.6 GHz RAM == 8GB of DDR3 in 2 sticks (matched pair) HDD == seagate 3TB SATA3 @ 7200 rpm (new install 64-bit v12.04 FAILS) HDD == seagate 1TB SATA3 @ 7200 rpm (64-bit v10.04 WORKS for two years) HDD == seagate 250GB SATA2 @ 7200 rpm (new install 64-bit v12.04 WORKS) HDD == seagate 250GB SATA2 @ 7200 rpm (new install 64-bit v12.04 WORKS) GPU == nvidia GTX-285 ??? == no overclocking or other funky business USB == external seagate 2TB HDD for making backups DVD == one bluray burner (SATA) DVD == one DVD burner (SATA) 64-bit ubuntu v10.04 has booted and run fine on the seagate 1TB drive for 2 years.

  • 5.1 sound in Unity3d 3.5

    - by N0xus
    I'm trying to implement 5.1 surround sound in my game. I've set Unity's AudioManager to a default of 5.1 surround and loaded in a 6 channel audio clip that should play a sound in each of the different audio spots. However, when I go to run my game, all I get is flat sound coming out of my front two speakers. Even then, these don't play the sound they should (front speaker should play "front speaker" right should play "right speaker" and so). Both speakers just end up playing the entire sound file. I've tried looking to see if there is a parameter that I have missed, but information on how to set up 5.1 sound in Unity is lacking (or my google skills aren't that good) and I can't get it to work as intended. Could someone please either tell me what I'm missing, or point me in the right direction? My audio source is situated at point (0, 0, 0) with my camera also being in the same point. I've moved about the scene but the same thing happens as I've already described.

  • Rotating object along bezier curve: not rotating enough?

    - by Paul
    I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

  • Stuck at enemy movement

    - by Syed
    I am making a TD game in unity, Initially I made all of my enemy movements frame rate dependent say: I had a grid point1 at -22.65 and other at -21.1, diagrammatically: (-22.65) _________(-21.1)_______(-21.1+1.55) ...... so the distance on x axis between two points is 1.55, divided it by 25 jumps with each enemy jump of 0.062 of each frame. On reaching on next point of grid the enemy find again its path. All went fine until I have requirement of FastForward and Pause feature. I used timeScale property of unity but it wont work as they are frame dependent. I also tried double speed of enemy on clicking fast forward button at any time, it has some issues that enemy jumps are now less and it fails to reach on next grid point. Could someone suggest me solution to my problem. Do I need to change the enemy movement code to make it frame independent ?? I need the enemy to reach on the grid specific point I also need later to slow down any one enemy's speed when tower fires on it. Thnx

  • Ubuntu keyboard shortcuts - two-part question

    - by Don
    Background: I come from a Windows background and just started dual-booting Ubuntu (my first Linux experience) about 4 days ago. So my systems are Windows 7/Ubuntu 12.04, and so far I'm loving Ubuntu. I am a dedicated mouse-abolitionist (trackpads are hell) and do most of my browsing and navigation with keyboard shortcuts. However, on switching to Ubuntu, a lot of my keyboard shortcuts are gone, and my productivity has resultantly taken a huge hit anytime I am using Ubuntu. Problem 1: My computer was designed to display on-screen notifications for a second when I hit caps-lock or num-lock, and there are no constant indicators of the lock status (LEDs, etc). In Ubuntu, the keys still worked, but the notifications were gone. Googling got me a tutorial on key-binding(Compiz) and scripts, so now I have capslock and numlock running this script: #!/bin/bash icon="/usr/share/icons/gnome/scalable/devices/keyboard.svg" case $1 in 'scrl') mask=3 key="Scroll" ;; 'num') mask=2 key="Num" ;; 'caps') mask=1 key="Caps" ;; esac value=$(xset q | grep "LED mask" | sed -r "s/.*LED mask:\s+[0-9a-fA-F]+([0-9a-fA-F]).*/\1/") if [ $(( 0x$value & 0x$mask )) == $mask ] then output="$key Lock" output2="On" else output="$key Lock" output2="Off" fi notify-send -i $icon "$output" "$output2" -t 1000 But, whether turning it off or on, the notifications always say that I have turned it on. Is there an easy fix for this, or an easier way to work it to get it do display the CORRECT notifications? Problem 2: I'm not sure if this is because of my keyboard or Ubuntu. In Windows, I use Chrome and use the ctrl+pgUp/pgDwn shortcuts quite a bit to switch between tabs. On my keyboard, I can enter pgUp and pgDwn by either disabling NumLock and hitting 9 or 3 respectively on the 10key. Alternately I can hold the fn key and hit up or down arrow. The first method is the one I very heavily relied upon, and it works in Firefox for Ubuntu, but not in Chrome nor in Chromium. The second method (ctrl + fn + up/down) works fine in Chrome. However, I'd dearly like to find a method to make the first method work. Any suggestions? Thanks in advance for your help. Update: @julien: I've checked the keyboard layout options - I didn't find anything that seemed useful for this goal. @Marty: The script runs once when the button is pressed. In Compiz, I've tied those two keys to the script, so when I press the button, it runs the script with the button pressed as a parameter. Update: @elmicha: Thanks. That one works a lot better, and it even pops an icon into the status bar when caps lock is on. There's still a very slight problem in that if I quickly tap the key twice, the image will show that it has been turned on and then turned off, and the notifaction will come and go from my status area, but the text of both notifications will be "Caps Lock on". Same with Num Lock. However, if the time between presses is long enough for the first notification to disappear, everything displays correctly. Given how quickly the notifications disappear, I don't expect this will pose too much of a problem for me.

  • When I shoot from a gun while walking, the bullet is off the center, but when stand still it's fine

    - by Vlad1k
    I am making a small project in Unity, and whenever I walk with the gun and shoot at the same time, the bullets seem to curve and shoot off 2-3 CMs from the center. When I stand still this doesn't happen. This is my main Javascript code: @script RequireComponent(AudioSource) var projectile : Rigidbody; var speed = 500; var ammo = 30; var fireRate = 0.1; private var nextFire = 0.0; function Update() { if(Input.GetButton ("Fire1") && Time.time > nextFire) { if(ammo != 0) { nextFire = Time.time + fireRate; var clone = Instantiate(projectile, transform.position, transform.root.rotation); clone.velocity = transform.TransformDirection(Vector3 (0, 0, speed)); ammo = ammo - 1; audio.Play(); } else { } } } I assume that these two lines need to be tweaked: var clone = Instantiate(projectile, transform.position, transform.root.rotation); clone.velocity = transform.TransformDirection(Vector3 (0, 0, speed)); Thanks in advanced, and please remember that I just started Unity, and I might have a difficult time understanding some things. Thanks!

  • Starting an Erlang slave node in escript fails when using custom Erlang in Ubuntu 10.4

    - by Adam Lindberg
    I have the following escript: #!/usr/bin/env escript %%! -name [email protected] main(_) -> NodeName = test, Host = '127.0.0.1', Args = "", {ok, _Node} = slave:start_link(Host, NodeName, Args), io:format("Node started successfully!"). When running it on Ubuntu 10.04 I get this: $ ./start_slave Node started successfully! $ I want to install my own Erlang (latest version, debug compiled files for dialyzer etc) since the stock install of Erlang on Ubuntu lacks some features. I put my Erlang binaries inside ~/Applications/bin. Starting Erlang normally works, and starting slave nodes inside an Erlang shell works as well. However, now my escript doesn't work. After about 60 seconds it returns an error: $ ./start_slave escript: exception error: no match of right hand side value {error,timeout} Even if I change the first line to the escript to use my erlang version, it still does not work: #!/home/user/Applications/bin/escript The slave node is started with a call to erlang:open_port/2 which seems to be using sh which in turn does not read my .bashrc file that sets my custom PATH environment variable. The timeout seems to occur when slave:start_link/3 waits for the slave node to respond, which it never does. How can I roll my own installation of Erlang and start slave nodes inside escripts on Ubuntu 10.4?

  • Can't reboot netbook with any of the reboot parameters

    - by Delan Azabani
    I have a Sony VPCW218AG netbook that I've dual-booted with Ubuntu 10.10. Unlike the preinstalled Windows 7, Ubuntu will not reboot on this computer. Rebooting from Gnome, using the reboot command and SysRq+REISUB all don't work; they end hanging with a blank screen. I have read that Atom netbooks don't have a keyboard controller and therefore the default reboot method, kbd, won't work. I have actually tried all ten reboot= parameters listed here; none of them work. I have also tried disabling ACPI with noacpi acpi=off for each one; that didn't help either. Are there any other things I can try to fix the rebooting problem?

  • newly added files don't sync down

    - by poolie
    I added some files into my Ubuntu One/My Files folder on my desktop machine. I can see them in the U1 web ui. My laptop is connected to the same U1 account, and in the Ubuntu One preference pane I can see it's connected to the account. However, my new files never download. In syncdaemon.log I can see it checking a bunch of other existing files, and then the file ends with many repetitions of 2011-01-04 11:05:42,277 - ubuntuone.SyncDaemon.Main - NOTE - ---- MARK (state: <State: 'READY' (queues WORKING_ON_METADATA connection 'Not User With Network')>; queues: metadata: 1; content: 0; hash: 0, fsm-cache: hit=5086 miss=69) ---- I do have a working network connection.

  • Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

    - by Madiyaan Damha
    I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,

  • Disk utility running for a long time

    - by Nik
    I had a spare, old external usb hard disk which stopped working long time back due to improper removal of disk. I tried fixing it in windows (when I did not have ubuntu yet), however I couldn't fix it. So I tried formatting the disk and creating a new partition using the disk utility in ubuntu. However it seems to keep running without any indication of the progress or whatsoever. I have no idea what is happening. I have attached a screenshot below to show what I mean. As you can from the screenshot above it seems to be working on it but no indication on the progress or what it is doing. Any attempt to exit it or do any other task like safe removal or format partition leads to the the following dialog box. What should I do? Wait or restart the computer..???

  • Installing on a Lenovo S10-3

    - by Søren Hauberg
    I'm trying to install Ubuntu 10.10 netbook edition on my Lenovo S10-3. According to the release notes, there is a bug in the kernel that forces me to add intel_idle.max_cstate=0 to the kernel parameters. I did this when booting the install CD and I was able to install Ubuntu. During the installation I chose to fetch updates from the net. Now when I try to boot the machine it just hangs. I have tried booting the machine as-is and I have tried adding the above-mentioned kernel parameters. Same experience. So, my questions is how do I install 10.10 in this machine and how do I boot it after I've installed the OS?

  • Which, among the humble indie bundle V games, work on 10.04?

    - by daithib8
    Inevitably, I've coughed up for the latest Humble Bundle, containing 5 games: Amnesia, Bastion, Limbo, Psychonauts and Superbrothers: Sword and Sorcery. At the download page it says download for ubuntu but after that it transpired (after much head scratching) that the three games it lists "are not available for your version of ubuntu". The other two, Bastion and Psychonauts "will appear on the page soon", but until then does anybody think they might work? I don't want to to be disappointed after downloading a 4gb file, causing me to reminisce on childhood memories of loading 8-bit tape games for 45 minutes only to find out that you had to reload them once you died after 30 seconds in.

  • Kinetic Scroll in Maverick

    - by Shoaib
    I have Sony VAIO FW 230J laptop. I was using Lucid and upgraded my system to Maverick beta in September 2010. Although there were few issues with beta release on my system although I did not felt myself in any deadlock. The most notable experience on my ubuntu was the smooth and kinetic scrolling and very sensitive touch pad experience with finer control that was oddly normal in previous releases and even on windows 7 currently. Definitely this release of ubuntu is improved for touch UI experience. I believe that this is magic of 10.10. For my official system I waited until the final release was out. After installing (upgrading) official system to Maverick I am not feeling the same smooth and kinetic scroll experience. My laptop has Graphics: Intel DMA-X4500MHD while my official desktop has Graphics: Intel DMA-X4500HD Do I need to install or update some software package to have similar kinetic scroll experience?

  • When syncing, removed contacts still show upp (One contacts)

    - by Niklas
    Hi! I just tried out using the Ubuntu One Contacts app for android. First I imported all the contacts from my phone, SIM-card and Google mail account, then I spent quite a while removing duplicates which got imported. Then I tried to sync it for the first time. The strange thing is that I also got all the contacts which I removed from my contacts list on the website. So I have to set "show only contacts with phone numbers" to get all the email adresses I imported from google ealier to not show up, even though I deleted them from the contacts list and have only Ubuntu One contacts showing. Why is that? Thank you!
