Info

C++ C++ Compiler: This is an actual C++ compiler, which will be used to compile your source code into final executable program. Most C++ compilers don't care what extension you give to your source code, but if you don't specify otherwise, many will use .<strong>cpp</strong> by default. Most frequently used and free available compiler is GNU C/C++ compiler, otherwise you can have compilers either from HP or Solaris if you have the respective Operating Systems. Installing GNU C/C++ Compiler: UNIX/Linux Installation: If you are using Linux or UNIX then check whether GCC is installed on your system by entering the following command from the command line: $ g++ -v If you have installed GCC, then it should print a message such as the following: Using built-in specs. Target: i386-redhat-linux Configured with: ../configure --prefix=/usr ....... Thread model: posix gcc version 4.1.2 20080704 (Red Hat 4.1.2-46) If GCC is not installed, then you will have to install it yourself using the detailed instructions available at http://gcc.gnu.org/install/ . Mac OS X Installation: If you use Mac OS X, the easiest way to obtain GCC is to download the Xcode development environment from Apple's website and follow the simple installation instructions. Xcode is currently available at developer.apple.com/technologies/tools/. Windows Installation: To install GCC at Windows you need to install MinGW. To install MinGW, go to the MinGW homepage, www.mingw.org, and follow the link to the MinGW download page. Download the latest version of the MinGW installation program which should be named MinGW-.exe. While installing MinGW, at a minimum, you must install gcc-core, gcc-g++, binutils, and the MinGW runtime, but you may wish to install more. 4
C++ Add the bin subdirectory of your MinGW installation to your PATH environment variable so that you can specify these tools on the command line by their simple names. When the installation is complete, you will be able to run gcc, g++, ar, ranlib, dlltool, and several other GNU tools from the Windows command line. 5
