When you launch Code::Blocks for the first time, it will scan the system for any supported compilers (it takes virtually no time). After this scan completes, Code::Blocks will have been configured for the found compiler(s). Code::Blocks will also be configured even for compilers that were not found (default installation settings will be used for each of those compilers).

For more info on how to download and install each of the above compilers, please read on.


Currently supported compilers, at the time of this writing are:

Downloading the GNU GCC compiler & GDB debugger

Go to MinGW's downloads page and download the file named MinGW-x.y.z.exe, where x, y and z are version numbers. At the time of this writing, this file is MinGW-3.1.0-1.exe. If you consider yourself lucky, you might also try MinGW-3.2.0-rc-3.exe. It's not a stable release yet, but it works and lacks some bugs the older version has. These setup files contain everything needed to compile and debug windows programs.

Downloading the Microsoft Visual C++ Free Toolkit 2003

Go to this MSDN site and click on the link labeled "Download the Visual C++ Toolkit 2003". This will download the setup file.

NOTE: This download is not sufficient for building windows programs. You will also have to download and install the Microsoft Platform SDK...

Downloading the Borland C++ Compiler 5.5

NOTE: At some point, you will be asked to register with Borland and fill out a survey. Registration is free.

Go to Borland's downloads and click on the link labeled "Compiler". After you accept the license agreement, you will be provided with download links to the setup file.

Downloading the Digital Mars C/C++ Free Compiler

Go to DigitalMars. Accept the license agreement and you'll be redirected to a page containing download links.

In that page, download:

  • The Digital Mars C/C++ Compiler (dm8**
  • The Basic Utilities (
  • The STLport library (

Open dm\bin\sc.ini in a text editor, and replace the line




Configuring CodeBlocks to use the Intel C++ Compiler

Note: this info is for 1.0RC1 and previous versions, now C::B haves direct support for Intel C++.

After various user requests, we decided to post here the info to support the Intel Compiler on CodeBlocks. This should be easy, since the Intel Compiler can emulate the MSVC++ compiler.

  • change MS Toolkit linker from cl.exe to icl.exe
  • add (installation path to the Intel C++)\Ia32\Bin to the "Programs -> Extra paths"
  • add "-D_USE_INTEL_COMPILER" to "Compiler options"
  • add (installation path to the Intel C++)\Ia32\Include and \lib to the "Global compiler options -> Directories"
  • add some options like "/QaxK" to the "Compiler options" (icl -help)


Currently supported compilers, at the time of this writing are:

Downloading the GNU GCC compiler & GDB debugger

Under Linux you'll, most probably, already have everything that is needed in order to compile. All major Linux distributions (RedHat, Debian, SuSE, Mandriva, Gentoo, ArchLinux, etc) come with GCC & GDB preinstalled. To make sure you have have gcc installed, go to your terminal and type 'gcc -v'. In case you have GCC installed, you will get GCC's compile options and version number.

Mac OS X

The Mac OS X port efforts has began recently, but it should be a matter of time until these compilers will be supported:

Under Mac you'll need to install Xcode Tools from

This will install Apple versions of:

Compiler-neutral setup steps

Now that you have downloaded the setup file of the compiler of your choice, launch its installation by double-clicking on the setup file. The actual installation process is really simple. Just press "Next" all the way and you 're done.

If you installed the compiler on its default installation directory, there is nothing more to configure. Launch Code::Blocks and you 're all set :)

If that is not the case, launch Code::Blocks. If it is the first time you launch it, the compiler auto-detection will be launched. If your compiler was not auto-detected, go to "Settings/Configure plugins/Compiler", select the compiler you installed, switch to the "Programs" page and press "Auto-detect". If you get a message saying that the compiler was auto-detected, congratulations! If not, then press the button with the three dots next to the "Auto-detect" button and select the installation directory of your compiler manually.

NOTE: The compiler's installation directory is exactly this: the installation directory. Not the "bin" subdirectory nor any other.
