Development Environment Setup on Linux
|
|
######################################
|
|
|
|
This section describes how to set up a Linux development system.
|
|
|
|
After completing these steps, you will be able to compile and run your Zephyr
|
|
applications on the following Linux distributions:
|
|
|
|
* Ubuntu 14.04 LTS 64-bit
|
|
* Fedora 22 64-bit
|
|
|
|
Where needed, alternative instructions are listed for Ubuntu and Fedora.
|
|
|
|
Installing the Host's Operating System
|
|
**************************************
|
|
|
|
Building the project's software components including the kernel has been
|
|
tested on Ubuntu and Fedora systems. Instructions for installing these OSes
|
|
are beyond the scope of this document.
|
|
|
|
Update Your Operating System
|
|
****************************
|
|
|
|
Before proceeding with the build, ensure your OS is up to date. On Ubuntu,
|
|
you'll first need to update the local database list of available packages
|
|
before upgrading:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo apt-get update
|
|
$ sudo apt-get upgrade
|
|
|
|
On Fedora:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo dnf upgrade
|
|
|
|
Note that having a newer version available for an installed package
|
|
(and reported by ``dnf check-update``) does not imply a subsequent
|
|
``dnf upgrade`` will install it, because it must also ensure dependencies
|
|
and other restrictions are satisfied.

Installing Requirements and Dependencies
|
|
****************************************
|
|
|
|
Install the following with either apt-get or dnf.
|
|
|
|
Install the required packages in a Ubuntu host system with:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo apt-get install git make gcc g++ python3-ply ncurses-dev
|
|
|
|
Install the required packages in a Fedora host system with:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo dnf group install "Development Tools"
|
|
$ sudo dnf install git make gcc glibc-static libstdc++-static python3-ply ncurses-devel
|
|

|
|
|
|
Installing the Zephyr Software Development Kit
|
|
==============================================
|
|
|
|
Zephyr's :abbr:`SDK (Software Development Kit)` contains all necessary tools
|
|
and cross-compilers needed to build the kernel on all supported
|
|
architectures. Additionally, it includes host tools such as a custom QEMU and
|
|
a host compiler for building host tools if necessary. The SDK supports the
|
|
following architectures:
|
|
|
|
* :abbr:`X86 (Intel Architecture 32 bits)`
|
|
|
|
* :abbr:`X86 IAMCU ABI (Intel Architecture 32 bits IAMCU ABI)`
|
|
|
|
* :abbr:`ARM (Advanced RISC Machines)`
|
|
|
|
* :abbr:`ARC (Argonaut RISC Core)`
|
|
|
|
* :abbr:`NIOS II`
|
|
|
|
Follow these steps to install the SDK on your Linux host system.
|
|
|
|
#. Download the latest SDK self-extractable binary.
|
|
|
|
Visit the `Zephyr SDK archive`_ to find all available SDK versions,
|
|
including the latest version.
|
|
|
|
Alternatively, you can use the following command to download the desired
|
|
version, replacing <version> with the version number you wish to download.
|
|
|
|
.. code-block:: console
|
|
|
|
$ wget https://nexus.zephyrproject.org/content/repositories/releases/org/zephyrproject/zephyr-sdk/<version>-i686/zephyr-sdk-<version>-i686-setup.run
|
|
|
|
#. Run the installation binary, follow this example:
|
|
|
|
.. important::
|
|
Make sure you have installed all required packages for your host
|
|
distribution as described in the previous section
|
|
`linux_required_software`_ otherwise the SDK installation will fail.
|
|
|
|
.. code-block:: console
|
|
|
|
$ chmod +x zephyr-sdk-<version>-i686-setup.run
|
|
|
|
$ ./zephyr-sdk-<version>-i686-setup.run
|
|
|
|
There is no need for `sudo` if the SDK is installed in the current
|
|
user's home directory.
|
|
|
|
#. Follow the installation instructions on the screen. The
|
|
toolchain's default installation location is :file:`/opt/zephyr-sdk/`.
|
|
To install in the default installation location, you will need to use sudo. It is recommended
|
|
to install the SDK in your home directory and not in a system directory.
|
|
|
|
#. To use the Zephyr SDK, export the following environment variables and
|
|
use the target location where SDK was installed, type:
|
|
|
|
.. code-block:: console
|
|
|
|
$ export ZEPHYR_GCC_VARIANT=zephyr
|
|
|
|
$ export ZEPHYR_SDK_INSTALL_DIR=<sdk installation directory>
|
|
|
|
To use the same toolchain in new sessions in the future you can set the
|
|
variables in the file :file:`${HOME}/.zephyrrc`, for example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ cat <<EOF > ~/.zephyrrc
|
|
export ZEPHYR_GCC_VARIANT=zephyr
|
|
export ZEPHYR_SDK_INSTALL_DIR=/opt/zephyr-sdk
|
|
EOF
