Version 0.11.0-2 is a maintenance release; it updates to the latest upstream master.

The xPack OpenOCD is a standalone cross-platform binary distribution of OpenOCD.

There are separate binaries for Windows (Intel 32/64-bit), macOS (Intel 64-bit) and GNU/Linux (Intel 32/64-bit, Arm 32/64-bit).


The binary files are available from GitHub releases.


  • Intel GNU/Linux 32/64-bit: any system with GLIBC 2.15 or higher (like Ubuntu 12 or later, Debian 8 or later, RedHat/CentOS 7 later, Fedora 20 or later, etc)
  • Arm GNU/Linux 32/64-bit: any system with GLIBC 2.23 or higher (like Ubuntu 16 or later, Debian 9 or later, RedHat/CentOS 8 or later, Fedora 24 or later, etc)
  • Intel Windows 32/64-bit: Windows 7 with the Universal C Runtime (UCRT), Windows 8, Windows 10
  • Intel macOS 64-bit: 10.13 or later


The full details of installing the xPack OpenOCD on various platforms are presented in the separate Install page.

Easy install

The easiest way to install OpenOCD is with xpm by using the binary xPack, available as @xpack-dev-tools/openocd from the registry.

With the xpm tool available, installing the latest version of the package and adding it as a dependency for a project is quite easy:

cd my-project
xpm init # Only at first use.

xpm install @xpack-dev-tools/openocd@latest

ls -l xpacks/.bin

To install this specific version, use:

xpm install @xpack-dev-tools/openocd@0.11.0-2.1

For xPacks aware tools, like the Eclipse Embedded C/C++ plug-ins, it is also possible to install OpenOCD globally, in the user home folder.

xpm install --global @xpack-dev-tools/openocd@latest

Eclipse will automatically identify binaries installed with xpm and provide a convenient method to manage paths.


To remove the links from the current project:

cd my-project

xpm uninstall @xpack-dev-tools/openocd

To completely remove the package from the global store:

xpm uninstall --global @xpack-dev-tools/openocd


The xPack OpenOCD generally follows the official OpenOCD releases.

The current version is based on:

  • OpenOCD version 0.11.0, the development commit 918811529 from Oct. 2, 2021.


There are no functional changes.

Compared to the upstream, the following changes were applied:

  • a configure option was added to configure branding (--enable-branding)
  • the src/openocd.c file was edited to display the branding string
  • the contrib/60-openocd.rules file was simplified to avoid protection related issues.

Shared libraries

On all platforms the packages are standalone, and expect only the standard runtime to be present on the host.

All dependencies that are build as shared libraries are copied locally in the libexec folder (or in the same folder as the executable for Windows).


On GNU/Linux the binaries are adjusted to use a relative path:

$ readelf -d | grep runpath
 0x000000000000001d (RPATH)            Library rpath: [$ORIGIN]

In the GNU search strategy, the DT_RPATH has the highest priority, higher than LD_LIBRARY_PATH, so if this later one is set in the environment, it should not interfere with the xPack binaries.

Please note that previous versions, up to mid-2020, used DT_RUNPATH, which has a priority lower than LD_LIBRARY_PATH, and does not tolerate setting it in the environment.


Similarly, on macOS, the dynamic libraries are adjusted with otool to use a relative path.


The original documentation is available in the share/doc folder.


The binaries for all supported platforms (Windows, macOS and Intel & Arm GNU/Linux) were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

The scripts used to build this distribution are in:

  • distro-info/scripts

For the prerequisites and more details on the build procedure, please see the How to build page.

CI tests

Before publishing, a set of simple tests were performed on an exhaustive set of platforms. The results are available from:


The binaries were testes on Windows 10 Pro 32/64-bit, Intel Ubuntu 18 LTS 64-bit, Intel Xubuntu 18 LTS 32-bit and macOS 10.15.

Install the package with xpm.

The simple test, consists in starting the binaries only to identify the STM32F4DISCOVERY board.

A more complex test consist in programming and debugging a simple blinky application on the STM32F4DISCOVERY board. The binaries were those generated by simple Eclipse projects available in the xPack GNU Arm Embedded GCC project.

Deprecation notices

32-bit support

Support for 32-bit Intel Linux and Intel Windows will most probably be dropped in 2022. Support for 32-bit Arm Linux will be preserved for a while, due to the large user base of 32-bit Raspberry Pi systems.

Linux minimum requirements

Support for RedHat 7 will most probably be dropped in 2022, and the minimum requirement will be raised to GLIBC 2.27, available starting with Ubuntu 18 and RedHat 8.
