| 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: |
| |
| .. code-block:: console |
| |
| $ sudo apt-get update |
| |
| On Fedora: |
| |
| .. code-block:: console |
| |
| $ sudo dnf update |
| |

| |
| 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 gcc-multilib g++ libc6-dev-i386 \ |
| g++-multilib |
| |
| 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 glib-devel.i686 glib2-devel.i686 \ |
| glibc-static libstdc++-static glibc-devel.i686 |
| |
| .. _zephyr_sdk: |
| |
| 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:`IA-32 (Intel Architecture 32 bits)` |
| |
| * :abbr:`ARM (Advanced RISC Machines)` |
| |
| * :abbr:`ARC (Argonaut RISC Core)` |
| |
| 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: |
| |
| .. 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 |
