Depending on how you obtained the CDT, you might have also
received a toolchain with a built-in CDT integration. However, if
you downloaded the CDT from an update site, then you will require a
toolchain before you can build and debug any projects.

The base CDT supports integration with the GNU toolchain. This
includes GNU's make, gcc compiler, and gdb debugger utilities. If
you require a toolchain to build software for your development
host, this is the best choice to get started.

Each platform that runs the CDT requires different steps to
acquire this toolchain.

Linux

All Linux distributions include the GNU toolchain. They may not,
however, be installed by default. For instructions about installing
the GNU toolchain for Linux, see the instructions for your
particular distribution.

Windows

For windows, MinGW, and Cygwin are the two main choices for
acquiring the GNU toolchain:

• Cygwin is a port of
  the Linux environment to Windows. It provides a compatibility layer
  in a set of DLLs. These DLLs are GPL licensed, making any
  code that links to them also subject to the GPL. Cygwin, however,
  does provide the fullest implementation of the GNU toolchain by
  supporting the GNU libc C runtime library.

• MinGW is a port of
  the GNU toolchain to the Windows platform. The biggest difference
  over Cygwin is that MinGW uses the Windows C runtime libraries
  (mscvrt) instead of GNU's libc. As a result, a compatibility layer
  is not required, thus avoiding the GPL issues with Cygwin. There
  are differences, though, between the Windows and GNU C runtime
  libraries that will make writing portable applications more
  difficult.

  However, MinGW provides the best integration support with the
  CDT due to it's direct support for the Windows environment.

  The following are instructions and links on how to install the
  current version of MinGW. Note that these links may become
  inaccurate over time as new versions of MinGW components are
  introduced. Please check the MinGW
  File Release section for the latest versions.

  1. Download and run the MinGW setup program, MinGW-5.1.3.exe.
  2. Select download and install the MinGW base tools and the g++
     compiler. You may select the Current or Candidate version of these
     tools. You may also install any of the other available compilers as
     well.

     Do not install the MinGW Make feature as the MSYS version
     of make from step 5 is a more complete implementation of make.

  3. The MinGW setup program currently does not install the gdb
     debugger. To install the debugger, download the file from the
     following location: gdb-6.6.tar.bz2
  4. Extract the contents of the file gdb-6.6.tar.bz2 to the same
     location where you installed MinGW.
  5. If you want to use Makefile projects, download and run the
     setup program from the following location: MSYS-1.0.10.exe.
     MSYS provides an implementation of make and related command line
     tools. This is not required for other types of projects with the
     MinGW toolchain, which use CDT's internal build tools to perform
     the build.

Other Platforms

The GNU toolchain is supported on all platforms that the CDT
supports. For instructions about installing the GNU toolchain on
your platform, see your platform vendor.
