I've slackware 13.1 and anytime I try the following commands in irb:
Code:
require 'rubygems'
require 'Qt4'
or
Code:
require 'rubygems'
require 'plasma_applet'
i receive the following error:
LoadError: no such file to load -- Qt4
LoadError: no such file to load -- plasma_applet
now I'm wondering what packages or gems I need to make it work?
I'm trying to build/install KDE 4.5.4, but I run into problems with the bindings package. Build fails with the following:
[Code]....
I'm building using the KDE slackbuild from sources dir, with the new KDE packages. edit: Well I decided to just take the risk of a not working KDE and commented out the bindings package. All other packages build fine. After this I crossed my fingers and rebooted, KDE loaded up. I gave the bindings package another go, and to my surprise it did build now. Got KDE up to date and it seems to be running fine.
I've been using rubyripper quite happily on Karmic, now I've moved to Lucid and discovered a bit of an issue. rubyripper will pause for several minutes between tracks with ruby 1.8. If I upgrade to ruby 1.9.1 the gui client won't run due to an issue with libgtk2-ruby not being available for 1.9.1.
The cli version of rubyripper under 1.9.1 is blazingly fast, so that is what I'm using at the moment, but I do prefer the gui.
Anyone have any insight into this? Googling suggests there may be a bug in ruby 1.8.7 that caused the long pauses, but it was supposed to have been fixed in 1.8.7.249 i.e. the default Lucid version.

There are a few things not working properly. Ruby version manager seems ok but untill i get working with ruby i don't know if it is working properly. One thing that is not there is irb Interactive ruby is not available according the the message i get.
Well i have no idea what readline is but i did everything that is on that webpage referance page [url]. I have got a lot of progress and learned heaps about linux shell and bash terminal. The thing is i need to get this going and have tried feenode but it is very foreign and how it works i do not have a clue. I have got 2 things resolved so far through this forum but using other threads in it. i need to get irb going before i can progress to using ruby on Rails properly.
I am using a Eeepc running ubuntu easy peasy its version 9.04 of ubuntu. I need the whole of rails to work and want to get a handle on using ruby version manager along with the apache stack with mysql/phpmyadmin and am using this as a dummy run for setting up a development system.
Is there anyway to run KDE without Plasma?At install I opted out of the kdebase-workspace package, but then didn't have the xwmconfig option to run KDE.Duplicating, then commenting out the original, and on the uncommented line: removing everything after 'Exec='. Taking the 'plasma.desktop' out. ...Deleting the entire file will only get it rewritten again by the system..Now it loads into beautiful void.I still have my GUI, complete with any kApps you might want: konsole, konqueror, and even krunner; but no panels or Desktop Activities.Is it still loading plasma only no longer implementing it? Am I losing precious RAM'CPU usage with plasma getting loaded without being used?
View 6 Replies View RelatedAfter falling out with KDE4.2.4 and using fluxbox for a while, I was sufficiently impressed with my experiments with KDE4.4.3 in slackware 13.1 that I decided to go back to KDE. In particular I'm keen to use plasma netbook on my eee pc 1000H.
But I've hit an annoying snag. The problem is that if I set it to use plasma netbook (System settings>Desktop>Workspace>Form factor>Netbook) it works just fine for the rest of that session but next time I startx it goes back to the Desktop form factor.
The strange thing is that this didn't used to happen, it only started recently and to the best of my knowledge I haven't made any other significant changes or updates to the system. I tried removing the ~/.kde dir and letting kde setup from scratch but that didn't help.
the little four squares in a grid beside the KDE launcher. Looked through all the Plasma widgets and didn't see this one. How do I get it back? Tried everything I could think of
View 3 Replies View Relatedi'm installing slack 13.1 on a friend's machine, and ran into what i would not call a bug, but more of an oversight. when selecting a desktop activity type, i must have definitely clicked the wrong item. i got a group of icons in the middle of the screen corresponding to the categories in the KDE menu. it worked ok, you could click on a category and get a group of icons for the apps, and click on the app to launch it. no problem there.... but you could not revert to a regular desktop.... at all.... no amount of right clicking would bring up the popup window i used to get there, and the plasma jellybean at the corner of the screen was gone. the plasma jellybean on the panel at the bottom brought up a panel menu, but never could get back to the desktop activity selection menu. the only way to get back to square one, was to delete the .kde subdirectory in the user's root directory.
View 8 Replies View RelatedI'm running Ubuntu in a virtualbox VM on windows, and none of the key-bindings that I define for compiz plugins (such as Grid and Put) work. I've tried letters and numbers by themselves, as well as combined with ALT, CTRL, and Super, but all fail.
View 1 Replies View RelatedI turn on my laptop running 64-bit karmic (if that helps anyone), open GNU Emacs 23.1.1 with the org files I've been working on, and for some reason it is not recognising standard key bindings, for the first time ever, with no reason I can conceive. What does "M-kp-enter is undefined" mean when it seemed well defined not long before? It seems using Esc-enter still works.. can anyone suggest if there are any config files I might need to edit, or what else could have gone wrong?
View 1 Replies View RelatedI have recently been trying to hack around a MTP plugin for the Exaile music player, but the first hurdle was getting any basic MTP operations to succeed. The following python calls caused a segmentation fault:
Code:
>>> import pymtp
>>> dev = pymtp.MTP()
>>> dev.connect()
>>> tracks = dev.get_tracklisting()
Segmentation fault
I had a look at pymtp 0.0.4.1-1 and I think that it is not in sync with the libmtp8 package (version 1.0.2) I have installed on my xubuntu 10.04 system. I have looked at the libmtp.h file for 1.0.2 and made some changes to pymtp which appear to do the job - no more crash, but I haven't yet tested the other parts of the interface. Feel free to use the attached patched file. I will try to get it to the package owner for further testing and hopefully an eventual package update.
I have (normal) Ubuntu 11.04 installed and I used the Ubuntu Software Center to install LXDE. I'm stuck on 2 problems though, and I'm not sure how to fix them.1. How do I change key bindings in LXDE? Specifically, I want to use Super+up/down/left/right change between workspaces, not the defaultCtrl+Alt+up/down/left/right. I have a script that I have set to auto-run on startup in my standard Unity session; I created a script and added it to the startup programs list there. However, I need to remove that script from LXDE ONLY, so that in the Unity session it will continue to run, and in the LXDE session it will NOT run

I would like to install the rmagick gem under ruby ree-1.8.7. Like every time, the installation routine does complain about two different version being installed which are actually the same. I have every, really every imagemagick package installed:

GraphicsMagick-1.3.12-1.15.i586

(Using Archlinux) I downloaded Ruby 1.8.7-174 a while ago and installed it via the tarball (not pacman). I was trying to update to 1.8.7-299, but I can't get it to work. Per the readme, I do the following steps, all of which complete without error:
./configure
make
make install
After install finishes however, I still have -174 installed instead of -299.
Terminal, I type ruby, I hit enter, and nothing happens. I'm given a blank line that I can type and enter, and again, nothing happens. I'm stuck, is there a way to fix this without closing the terminal window?

Trying to understand my ruby folder structure? Why my gems are scattered all over and why they aren't recognised commands. I'll explain how my installation looks like first:
/usr/bin/ruby
/usr/bin/ruby1.8
/usr/bin/ruby1.9.1
The first is a soft link to ruby1.9.1 because the "ruby" command didn't work in the terminal. I did the same with "gem". I installed rubygems through downloading, extracting and then running setup.rb here: (I created the "ruby" folder)
/home/pc/ruby/rubygems-1.7.2/setup.rb
/usr/bin/gem
/usr/bin/gem1.8
/usr/bin/gem1.9.1
I installed a few gems with "sudo gem install"
> gem list
*** LOCAL GEMS ***
compass (0.10.6)
haml (3.0.25)
mustache (0.99.3)
rake (0.8.7)
So far so good? Well not quite, as it turns out the command "compass version" doesn't seem to exist. My confusion grows with each folder I look into. The following path doesn't make any sense to me, for example. Why would it be hidden? Why is mustache the only gem inside this folder?
/home/pc/.gem/ruby/1.9.1/cache/mustache-0.99.3.gem
First of all, here is "gem environment", which makes even less sense, because I have definately installed rubygems-1.7.2 like I told you in the first paragraph, but here it shows an ancient version 1.3.7. Why? I installed Ubuntu the day before yesterday.
RubyGems Environment:
- RUBYGEMS VERSION: 1.3.7
- RUBY VERSION: 1.9.2 (2010-08-18 patchlevel 0) [x86_64-linux]
- INSTALLATION DIRECTORY: /var/lib/gems/1.9.1
- RUBY EXECUTABLE: /usr/bin/ruby1.9.1
- EXECUTABLE DIRECTORY: /var/lib/gems/1.9.1/bin
- RUBYGEMS PLATFORMS: .....
Ruby --version returns "ruby 1.8.7"...........
Also, as it turns out, all gems are installed into this folder (mustache too! even though it already is inside the other folder), just as "ruby environment" claims:
/var/lib/gems/1.9.1/gems. But none of these gems work. I can't call any of these, except rake. So here is where I probably made the mistake, I think I used "apt-get install rake" in addition to "gem install rake", because the command "rake" wasn't recognised, and the command prompt suggested it. I may have done so with rubygems too... I'm new to Linux, and I figured that the command prompt knew how to install this stuff properly. It can't be normal that I have to create syslinks all over, right? In Windows I didn't run into this problem.
I am using Red Hat Enterprise Version 5. There is a ruby program which use standard input as its input (e.g. the Ruby program process input from standard input). I think standard input should be keyboard, correct?
So, I think other kinds of input (non-standard input) should not work (i.e. the ruby program should not be able to read input from such non-standard input), but actually I have tried using pipe works, I am so confused because I think pipe should be some other kinds of input -- other than standard input, why it could work? i.e. put text "123" in abc.txt with pipe, could achieve the same result as using keyboard as input to type "123" for the ruby program.
cat abc.txt | ~/test/rubysrc/foo.rb
The site that used to host the language spec file for .erb/.rhtml for ruby/rails syntax highlighting is no more.If someone could attach the file for gtksourceview-2.It's located in /usr/share/gtksourceview-2.0/ language-specs/ and probably called rhtml.lang
