What OS do you use?

On Windows you should install cygwin (google it) and then, gcc will be there already. And on Windows you do not want to mess with tar.gz files. Just use gcc available in cygwin. And better do not use Windows at all.

On MacOS you have tar and gzip. See the note for Linux and use terminal. Usually, however, you do not want to mess with tar.gz files. Istead, there is a way to install gcc from img file like other Mac applications. Well, there are many other ways.

On Linux, gcc must be already installed. If you need newer package, use your package system. If you need exactly that tarball, then try to

tar zxvf filename.tar.gz
./configure
make
sudo make install

Cygwin is a Linux-like environment for Windows.

I just need an folder containing file G++.exe to compile a C++ source code (so i can use .bat to compile many C++ files in a time), Can Cygwin do that ? I downloaded the DecCpp 5 beta and it contains the g++ 3.4.2 which is not up to date (4.2.0). How can i use the most updated G++, i am using windows XP.

Thanks in advance.

G++ is for all OS it supports (of course including Windows).
In Windows, you should install MinGW. It includes a couple things you will enjoy

Zmieniłem pytanie.
Jest ono napisane po polsku z dopiskiem (tak, jak mówiłem), żeby się ze mną skontaktować - dla obcojęzycznych userów, choć wątpię czy ktoś skorzysta.
