If
you know what this is all about and you just need the update site
details:

• name: GNU
  ARM Eclipse Plug-ins


• URL: http://gnuarmeclipse.sourceforge.net/updates

Prerequisites

Since
these are Eclipse plug-ins, they obviously require a functional Eclipse CDT,
which requires Java.

Java

The
recommended package is the official Oracle Java SE.
The OpenJDK Java used in Ubuntu is also fine. The
minimum is JDK 1.5, or even JRE (the Java Runtime Environment), but, as said
before, better use the latest JDK. On OS X the last Apple Java implementation is
1.6, so it is recommended to use the Oracle 1.7 or later.

For
example, on Ubuntu 12.04 LTS, you can install the OpenJDK run-time and test if
it was properly installed with the following commands:

$ sudo apt-get install openjdk-7-jre

$ java -version

java version "1.7.0_55"

OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.12.04.2)

OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

Eclipse & CDT

If
you start from scratch, it is recommended to use the latest Eclipse available
(currently Eclipse 4.3 Kepler). Just go to the Eclipse download
site and get the Eclipse
IDE for C/C++ Developers archive appropriate for your platform,
preferably the 64-bit version. Unpack it at a place of your choice and start
using it.

CDT

As
mentioned before, the recommended way is to use a fresh Eclipse
IDE for C/C++ Developers for the cross ARM development projects.
Even if you did so, but especially If you did not do so, it is a good idea
to check if you really have the latest version available. For this,
enter the Eclipse menu and go to Help → Install
New Software

Install new software.

• select Work
  with: Kepler


• if
  the Group
  items by category is enabled, expand the Programming
  Languages group


• select
  the C/C++
  Development Tools feature


• click
  the Next button
  and follow the usual installation procedure

CDT install.

Compatibility issues

Please
note that starting with 1.1.x, compatibility with Eclipses previous than 4.3
Kepler was no longer possible. If, for any reasons, you need a solution for
older Eclipse versions, you can try the GNU ARM Eclipse Plug-in version 0.5.5,
but please keep in mind that this old version is no longer maintained.

Plug-ins install

The
following samples are from Eclipse 4.3 Kepler on OS X. Other platforms may
behave slightly different, but the idea is the same.

Warning: Be sure your Eclipse is 4.3 or later,
otherwise the plug-ins will refuse to install, without offering many
explanations.

The recommended way

The
recommended way to install these plug-ins is to use the Eclipse standard
install/update mechanism: In the Eclipse menu: Help → Install
New Software…

• in
  the Install window, click the Add… button (on future updates, just
  select the URL in the Work
  with:combo)


• fill
  in Name: with GNU
  ARM Eclipse Plug-ins


• fill
  in Location: with http://gnuarmeclipse.sourceforge.net/updates


• click
  the OK button

Add the GNU ARM Eclipse repository.

• normally
  the main window should list a group named CDT
  GNU Cross Development Tools; expand it


• (in
  case the main window will list There
  are no categorized items, you are probably using a very old version;
  disable the Group items by category option)


• select
  all the plug-ins (the one marked End
  of life is needed only for compatibility with previous version,
  normally can be safely skipped)


• click
  the Next button and follow the usual
  installation procedure

Plug-ins install

Once
you define the update site URL, further updates are greatly simplified (Help → Check
For Updates).

Installation problems

There
are cases when the on-line access to the SourceForge mirror servers might not be
reliable. In these cases the Eclipse update system may fail. For example:

Failed install.

If
repeated attempts fail (preferable restart Eclipse between attempts), an
alternative method would be to manually download the latest version archive and
to perform the install from it, as presented below.

The alternate way

If,
for any reason, you need to install a specific version of the plug-in, the
solution is to download the archive from SourceForge Files and to point the Eclipse update
mechanism to the local archive: In theEclipse menu: Help → Install
New Software…

• in
  the Install window, click
  the Add… button
  
  • in
    the Add Repository window,
    click the Archive… button
    
    • in
      the Repository
      archive window, select the downloaded .zip archive
    
    
    • click
      the OK button
  
  
  • click
    the OK button


• follow
  the usual installation procedure

Add repository from archive.

Toolchain and debugging support

By
completing the above steps, the Eclipse environment is ready, and you can start
creating projects right away. However, for being able to build and debug these
projects, you also need to install:

• the toolchain


• the
  optional build
  tools (if you are running
  on Windows)


• the debugging tools

Follow
the above steps and when everything is ready, proceed to create
and build a test project.

Support

If
you encountered any problems when installing the plug-ins, pleas refer to
the Support page and do
not post
comments to the blog pages containing support requests.
