can any one help me? the big problem of linux is that you have to type to install most of the apps! i'm searching for an application which can automatically install tarballs just by clicks(No linuxigeekly typing!) is there any thing like that???
I'm assuming you're using Ubuntu. If so, did you try Software Centre? does pretty much what you need. You select the software you want to install from a pretty graphical screen and it takes care of downloading and installing for you.
You mention that you'd like to install apps that are not available in Software Center. It'd be useful if you could provide examples. Most common-use applications are packaged and available in USC. Part of the reason is that apps distributed as source are considered of "intermediate" difficulty to install, you will need to use the command line for those, and even distros that compile everything, such as Gentoo, require someone to come up with a set of rules for how to compile each application.
That said, if you have specific applications that you'd like to see available in Software Center, and it's something that is likely to be of general use, you can request an Ubuntu package by following this procedure.
Yes, but not that I know of for Ubuntu. emerge (gentoo) and pacman (arch) are the two tools I am familiar with.
I think a better question is why are you installing from source code ?
Here is a great discussion about installing packages outside of your package manager
Yes it is a Fedora link, but the advice is spot on.
Other considerations are ;
LFS has some tools - http://www.linuxfromscratch.org/alfs/
Standard tools exist for configuring and building applications from source, e.g. autoconf and CMake. These tools are configurable and may not fit in your environment directly.
Take a car for example. You don't just go to a random seller and buy a random car from him. Instead, you try to find out what your preferences are and whether it suits you and your environment. (if you're very lengthy, you won't pick a small car).
Just install your software from the Ubuntu Software Center or Muon (for Kubuntu) if possible. Otherwise, have a look at the installation instructions on the website of the application, the README or INSTALL files. If you really want to use a certain program, you shouldn't be afraid of using the terminal if that's necessary. It does not bite you.
