--version shows up 4.4 on Debian Squeeze. Today I left Ubuntu because its simply not stable (about 50++ errors a day) and slow. And I dont like Unity. Debian is great. Reliable, fast and Gnome 2 is okay. I worked on a large c++ project and made heavy use of c++0x features.
My question is: how do I get at least gcc 4.6 on Debian?
Running a mixed system is no option. I mean changing sources.list and upgrade. And full upgrade is no option because of Gnome 3. I will have to wait for Debian MATE. But somehow this has to be accomplished...
You could build the GCC 4.7 (from its FSF source tar ball). This might be painful (it really depends upon your skills), and may take several hours of CPU. Before compiling it, install all the required dependencies (perhaps by compiling them from their source code), and read carefully the GCC install documentation several times.
I am not sure that you are right in avoiding mixing Debian/testing with Debian/stable. I am happily using Debian/unstable on all my desktops and laptops, so I get the latest released GCC.
When you build GCC 4.7.2 from the FSF source tarball, don't forget to build outside of the source tree. Read carefully about the configure options (you probably want --program-suffix=-4.7 for instance). Don't forget to enable plugins (with --enable-plugin at ..../configure time) in your GCC. You could perhaps be interested by MELT, a domain specific language to extend GCC, implemented as a [meta-] plugin.
If you dislike Gnome3 -which I do understand- you might try another Debian based distribution like Linux Mint, or simply use XFCE as your desktop.
You can install certain packages from testing while the others remain stable. See APT Preferences from the debian wiki.

I installed Cygwin on my laptop. After going through the instructions on netbeans site, i found that i need to change the path directory.
My path directory initially shows some java thing on that and if i change it then will it create some problem?
I basically Want to run C/C++ programs by NetBeans so I installed Cygwin thinking that it would help me.
Please Suggest me what to do.
Took this from the original guide
Cygwin is a Linux-like environment for Windows. It consists of a DLL
(cygwin1.dll), which acts as an emulation layer providing substantial
POSIX (Portable Operating System Interface) system call functionality,
and a collection of tools, which provide a Linux look and feel. The
Cygwin DLL works with all x86 and AMD64 versions of Windows NT since
Windows XP SP3. The API follows the Single Unix Specification as much
as possible, and then Linux practice. The major differences between
Cygwin and Linux is the C library (newlib instead of glibc). With
Cygwin installed, users have access to many standard UNIX utilities.
They can be used from one of the provided shells such as bash or from
the Windows Command Prompt. Additionally, programmers may write Win32
console or GUI applications that make use of the standard Microsoft
Win32 API and/or the Cygwin API. As a result, it is possible to easily
port many significant UNIX programs without the need for extensive
changes to the source code. This includes configuring and building
most of the available GNU software (including the development tools
included with the Cygwin distribution).

I have been developing a C++11 application against a modern compiler on my mac/linux, which works fine but then I tried to deploy it to a very old linux box (g++ 4.1.2: Feb 2007) and of course that's too old and the executable won't work.
This isn't surprising but now I'm wondering if there is a standard amount of time you are expected to support a compiler/standard?
I had a look around but there is no mention of this.. Should the support for a compiler version drop when the developers themselves deem it end of life and will not patch bugs?
You're the one running gcc (or g++). It's a compiler, used by developers. End-user systems may not have any version of gcc. It's glibc and libstdc++ you need to worry about. But in general, Linux does not aim for binary compatibility. Do not expect any binary executable to run properly on any other distribution/major version.
Conversely, glibc and libstdc++ are careful to work with old kernel versions, so you should be able to install (configure+make+install) the latest runtime support libraries on your Linux box, and then build your application for that.
The easiest way to do that is probably to install the same distribution and version that your target has, into a virtual machine. Then install the C++11 developer tools, and build your application.

I'm about to teach intro C++ class and would like to use Eclipse for the development/learning. In order for students to setup Eclipse C++ to work on Windows it will not be very intuitive to install the compiler then install Eclipse and configure it. My question, is there a way to bundle them together and then provide students with those files to extract on their computer and start development.
If you install MinGW to the default install location C:\MinGW then the Eclipse CDT will automatically detect the MinGW toolchain and configure itself correctly.
If you run into issues make sure the PATH variable points to C:\MinGW\bin, this can be done automatically by providing a script to your students but may not be neccecary as the MinGW installer should do it automatically.
Are all of your students working on the same computers such as lab computers? Or on their own computers, which may have different os and 64/32 bit?
If they are all working on the same platform you could create a directory with applicable java/eclipse/and c compilers and a quick tutorial with a script to set their environment variables.
If they are working on their own computers this becomes very complicated. They will need different versions of each java/eclipse/ c compiler and will probably each run into different issues.
I am a student and we tend to have old computers. The first time I tried to run eclipse cdt was on a computer with vista.
That being said, you can create a zip directory with several different options that they could download and install. This is a headache I had to do for my senior design team. 7 of us ran into 6 different issues.

I am a newbie in linux and programming. I want to learn linux command and use create some C and C++ programme to interact with the linux API from my windows XP. However, I am not sure how to set up the environment from my windows based computer.
What programme should I install? Also, it seems like linux has Ubuntu, Fedora. I heard of Red Hat as well. What is the difference and which one should I install?
Also, is there any difference between using linux with user interface like Ubuntu, using an IDE to create programme AND the command line terminal using VIM to create programme?
Besides, I have heard of using Valgrind to debug programme. Does Valgrind works together with an IDE in Ubuntu or works in command line terminal only? If my IDE already has debugger, do I still need Valgrind?
Sorry for such newbie questions.
Thanks.
Your question is very vague and prone to start argumentations and fights. Also, you miss-used many terminologies there and before you even start programming with Linux, you should first get acquainted with the OS, especially the terminal... But first things first, programming in C/C++ for Windows is not entirely the same as programming in C/C++ for Linux. If you want the latter, then use the latter.
My suggestion is this :
Grab VirtualBox and install it.
Download Ubuntu ; IMHO, Ubuntu is best for starters (or anyone as a matter of fact) because it has a lot of support, a good user base and is compatible with pretty much any Linux software installer (RPM, deb, etc.) You can choose any other distribution, it doesn't really matter, but I recommend this one. [1]
Start VirtualBox and create a new Ubuntu virtual machine. The steps are pretty straight forward, consult the documentation for any assistance). Your virtual machine may look something like :
1GB of RAM will be enough;
10GB of hard disk (you won't need much more, but you may increase the size if you think you'll need more space for /home, see next point)
a network adapter set a bridged
etc.
Install Ubuntu from the ISO that you have just downloaded (that you have mounted into VirtualBox as a CD-ROM device) You'll only need about 8GB of hard disk total for a typical, minimum Ubuntu installation (ext4+swap), however I recommend this setup.
Enjoy your installation. (Tip: now you can install the VirtualBox's Guest Additions.)
Open a terminal in your Ubuntu VirtualBox window and type sudo apt-get install build-essential to install the GCC compiler
Gedit is already installed by default with Ubuntu and it's a fairly good text editor compared to Windows' notepad. However, vim is not, but you can install it with sudo apt-get install vim in the terminal.
And voilà! You're all set to go to do some C/C++ programming in a Linux environment, where you can still have Windows in case you're stuck.
I also recommend you do most of your learning using the terminal (aka the command line) so you know how things work under the hood. Then, when you are familiar with the GCC compilier, MAKEFILEs, etc. you can install some IDE to avoid repeating tasks; The two best I have yet found are Ajunta and MonoDevelop. Both are available from the repositories.
Now, if you want to "create some C and C++ programs to interact with the linux API from [your] windows XP", You need, for example, to learn sockets and SSH; so you can connect to your Linux machine from your Windows machine and execute some commands remotely from your Windows applications. But before you do that, learn C/C++ and play around with Linux. For a newbie, you already have your hands full right there.
Good luck!
[1] Ubuntu (a Linux distribution) comes with Gnome as GUI, while Kubuntu with KDE and Xubuntu has XFCE. All of them (GUIs) are separate projects and you could have all of them installed on any Linux desktop installation. Even, you don't need any GUI with any Linux distribution; for example, VMWare's Virtual Appliance Marketplate have a whole bunch of ready-to-go Linux installations like that.
Try it with a VM or as a live-cd.
Valgrind is a command-line tool but maybe some IDEs use integrated it.
Under Linux you'll see, than most of the time an IDE is quite useless (not a troll).
You'll do your Makefile manually,...
Hope you'll enjoy' it.
Regards,
Learn 1 thing at a time.
If you want to learn to program first, try python first. It works in Windows and Linux and you get result faster
If you want to learn C++, get Visual C++ express or Cygwin/GCC
If you want to experience with Linux, get a distribution of your choice (Linux-Mint is a good introction, coming from Windows) and try it in a VM (VMWare Player or VirtualBox)
Try easy projects and only after that, worry about debuggers
If you try it in virtual machines (virtualbox or WMWare for example) you can test as many options you want before deciding what Linux distro you will want to use. There are a lot, but from what you listed, my personnal opinion is that Ubuntu is a lot easier than Fedora to start. I've never used RedHat so I can't tell but it hasn't the reputation of beeing a hard one (for experts).
Anyways, at least to start I recommend installing it with GUI (and after starting too unless it's a server...).
Regarding IDEs, you could try Eclipse and Netbeans. They run both on Windows and Linux but I'm not C/C++ programmer so I don't know if they are good at that job. I you don't use IDE, Vim is far from beeing the unique option (Vim "addicts" :) will say it is the unique productive one but that's a personnal choice and the learning time is not very short). Personnaly I prefer a good IDE or at least graphical editors for programming, not that I don't like the power and speed of the terminal with command line as I prefer to use it for system administration or configuration but not for programming where you stay a long time on it.
I don't know about Valgrind but Eclipse or Netbeans IDEs have debuggers of course.
Programming for Linux a series of projects to learn, for the steps, you may refer to:
Red Hat Certified System Administrator Ｉ ＆ＩＩ student-book which may help you to get the survival abilities in Linux, actually when you really understand the fields covered by these courses, you will have got the ability to find what to learn.

I'm looking for just a compiler for C++ (such as g++) for Windows, that I could run in my cmd.
I'm using notepad++ as my text editor and I want to set up a macro in there that can compile my programs for me.
I do not wish to install Cygwin though.
Any suggestions?
MinGW. It's GCC/G++ for Windows. It's much lighter than Cygwin. The main difference from Cygwin GCC is that it doesn't try to emulate UNIX APIs, you have to use the Windows APIs (and of course the standard C/C++ libraries). It also doesn't provide a shell and utilities like Cygwin, just the compiler.
There is also a related system called MSYS, which provides a shell, etc. like Cygwin, but this is not required. MinGW itself will run in CMD (but I highly suggest using something better like Bash, for your own sanity).
Visual C++ has a command line compiler, cl:
Compiler Command-Line Syntax (C++)
If you don't have Visual Studio, you can download the Windows SDK (newer version) or the Windows Driver Kit for free, and then use the CL.EXE command-line compiler as suggested by #Greg Hewgill.
Digital Mars is excellent.
Probably not what you're looking for, but just to add to the question for completeness, the Intel Optimizing Compiler works great on Windows, Linux and Mac Intel platforms. A bit on the pricey side, but for highly optimized compiles on Intel processors it's second to none.
I think that the TDM-GCC from Twilight Dragon Media is more convenient than the official MinGW release. I found it simpler to install and use.
The old Borland C++ non-IDE compiler is freely available:
http://cc.codegear.com/Free.aspx?id=24778
Here is Wikipedia's background on this free, Windows, command-line compiler:
http://en.wikipedia.org/wiki/Borland_C%2B%2B
With Windows 10, you can use g++ via the Windows Linux Subsystem.
Once you've set it up, install g++ using the bash terminal (this answer on Ask Ubuntu shows you how).
Bear in mind: you will only be able to run compiled C++ programs in the Ubuntu/bash environment, not from cmd/PowerShell directly:
C:\Folder> bash
User#Computer:/mnt/c/Folder$ g++ hello_world.cpp -o hello_world
User#Computer:/mnt/c/Folder$ ./hello_world
