[edit] Where to get a compiler

When you select your compiler you must take in consideration your system OS, your personal preferences and the documentation that you can get on using it.

One of most actualized and compatible compilers is GCC. The next section will show how to get a copy and install it on Windows. You can easily find information on the GCC website on how to do it under another OS. GCC is a decent choice, and can be obtained for free. Many Open Source platforms include a recent GCC version. Version 4.0 or later gives fairly good conformance to the C++ standard. Various IDEs are available to support GCC. For Windows, Microsoft Visual Studio Express is currently available free of charge (but not free as in non-proprietary) with a C++ compiler that can be used from the command line or from the supplied IDE. An IDE, or Integrated Development Environment, is generally a graphical environment which integrates functionality like editing, compiling, linking, and usually a help system etc.).

NOTE: In Appendix B:External References you will find references to other freely available compilers and even full IDEs you can use.

[edit] GCC

The GNU Compiler Collection is a free set of compilers developed by the Free Software Foundation, with Richard Stallman as one of the main architects.

There are many different pre-compiled GCC binaries on the Internet, some popular choices are listed below (with detailed steps for installation).

[edit] On Windows

Cygwin:

1. Go to http://www.cygwin.com and click on the "Install Cygwin Now" button in the upper right corner of the page.
2. Click "run" in the window that pops up, and click "next" several times, accepting all the default settings.
3. Choose any of the Download sites ("ftp.easynet.be", etc.) when that window comes up; press "next" and the Cygwin installer should start downloading.
4. When the "Select Packages" window appears, scroll down to the heading "Devel" and click on the "+" by it. In the list of packages that now displays, scroll down and find the "gcc-c++" package; this is the compiler. Click once on the word "Skip", and it should change to some number like "3.4" etc. (the version number), and an "X" will appear next to "gcc-core" and several other required packages that will now be downloaded.
5. Click "next" and the compiler as well as the Cygwin tools should start downloading; this could take a while. While you're waiting, go to http://www.crimsoneditor.com and download that free programmer's editor; it's powerful yet easy to use for beginners.
6. Once the Cygwin downloads are finished and you have clicked "next", etc. to finish the installation, double-click the Cygwin icon on your desktop to begin the Cygwin "command prompt". Your home directory will automatically be set up in the Cygwin folder, which now should be at "C:\cygwin" (the Cygwin folder is in some ways like a small Unix/Linux computer on your Windows machine -- not technically of course, but it may be helpful to think of it that way).
7. Type "g++" at the Cygwin prompt and press "enter"; if "g++: no input files" or something like it appears you have succeeded and now have the gcc C++ compiler on your computer (and congratulations -- you have also just received your first error message!).

MinGW + DevCpp-IDE

1. Go to http://www.bloodshed.net/devcpp.html, choose the version you want (eventually scrolling down), click on the appropriate download link! For the most current version, you will be redirected to http://www.bloodshed.net/dev/devcpp.html
2. Scroll down to read the license and then to the download links. Download a version with Mingw/GCC. It's much easier than to do this assembling yourself. With a very short delay (only some days) you will always get the most current version of mingw packaged with the devcpp IDE. It's absolutely the same as with manual download of the required modules.
3. You get an executable that can be executed at user level under any WinNT version. If you want it to be setup for all users, however, you need admin rights. It will install devcpp and mingw in folders of your wish.
4. Start the IDE and experience your first project!
   You will find something mostly similar to MSVC, including menu and button placement. Of course, many things are somewhat different if you were familiar with the former, but it's as simple as a handfull of clicks to let your first program run.

[edit] For DOS

DJGPP:

• Go to Delorie Software and download the GNU C++ compiler and other necessary tools. The site provides a Zip Picker in order to help identify which files you need, which is available from the main page.
• Use unzip32 or other extraction utility to place files into the directory of your choice (ie. C:\DJGPP).
• Set the envionment variables to configure DJGPP for compilation, by either adding lines to autoexec.bat or a custom batch file:

  set PATH=C:\DJGPP\BIN;%PATH%

  set DJGPP=C:\DJGPP\DJGPP.ENV

• If you are running MS-DOS or Windows 3.1, you need to add a few lines to config.sys if they are not already present:

  shell=c:\dos\command.com c:\dos /e:2048 /p

  files=40

  fcbs=40,0

Note: The GNU C++ compiler under DJGPP is named gpp.

[edit] For Linux

• For Redhat, get a gcc-c++ RPM, e.g. using Rpmfind and then install (as root) using rpm -ivh gcc-c++-version-release.arch.rpm
• For Fedora Core, install the GCC C++ compiler (as root) by using yum install gcc-c++
• For Mandrake, install the GCC C++ compiler (as root) by using urpmi gcc-c++
• For Debian, install the GCC C++ compiler (as root) by using apt-get install g++
• For Ubuntu, install the GCC C++ compiler by using sudo apt-get install g++
• If you cannot become root, get the tarball from ftp://ftp.gnu.org/ and follow the instructions in it to compile and install in your home directory.

[edit] For Mac OS X

Xcode has GCC C++ compiler bundled. It can be invoked from the Terminal in the same way as Linux, but can also be compiled in one of XCode's projects.
