***********************************
Build the ROCm Core SDK from source
***********************************

You can build the ROCm Core SDK from source using the open-source unified build
system `TheRock <https://github.com/ROCm/TheRock>`__. To learn more about the
motivation and architecture behind this system, see `ROCm Technology Preview:
ROCm Core SDK and TheRock Build System
<https://rocm.blogs.amd.com/software-tools-optimization/therock/README.html>`__.

This page consists mainly of references to `TheRock's README
<https://github.com/ROCm/TheRock?tab=readme-ov-file#building-from-source>`__
and `supporting development manuals
<https://github.com/ROCm/TheRock/blob/main/README.md#development-manuals>`__, 
which provide up-to-date build instructions and guidance for supported
platforms. See `TheRock Development Guide
<https://github.com/ROCm/TheRock/blob/main/docs/development/development_guide.md#therock-development-guide>`__
to learn about the overall build architecture.

.. tip::

   Building from source is recommended only if you need custom builds or are
   contributing to ROCm development.
   For most users, installing from official AMD releases is faster and easier.
   See :doc:`/install/rocm` for installation instructions.

Prerequisites
=============

A successful build depends on a correctly configured environment. Before you
begin, ensure your system meets all hardware and software requirements. Review the
following resources:

* `Environment setup guide
  <https://github.com/ROCm/TheRock/blob/main/docs/environment_setup_guide.md>`__

* :doc:`/compatibility/compatibility-matrix`

High-level build process
========================

For an overview of the build architecture, start with TheRock's `development guide
<https://github.com/ROCm/TheRock/blob/main/docs/development/development_guide.md>`__.
While specific commands vary by platform, the general workflow for building
from source involves these stages:

1. Clone the repository and install build dependencies. See :ref:`build-from-src-plat-setup`.

2. Configure the build: Use CMake feature flags to configure the build. This
   step allows you to target specific platforms, build subsets of ROCm Core SDK
   components, and toggle component features. See `Build configuration
   <https://github.com/ROCm/TheRock/blob/main/README.md#build-configuration>`__
   for optional and required build flags.

3. Execute the build: Run the build command to compile the source code. This
   can be a time- and resource-intensive process. See `CMake build usage
   <https://github.com/ROCm/TheRock/blob/main/README.md#cmake-build-usage>`__.

4. After a successful build, the outputs are available for use in downstream
   tasks. To learn more about build outputs, see the relevant `TheRock
   documentation <https://github.com/ROCm/TheRock/blob/main/docs/development/artifacts.md>`__.
   Common post-build tasks include:

   * Using ``build/dist/rocm``: When the build completes, you should have a
     build of ROCm in the ``build/dist/rocm/`` directory. See `Using installed
     tarballs <https://github.com/ROCm/TheRock/blob/main/RELEASES.md#using-installed-tarballs>`__
     for more information.

   * Building Python packages: Prepare the build artifacts for distribution as
     Python packages. See `Building Python packages
     <https://github.com/ROCm/TheRock/blob/main/docs/packaging/python_packaging.md#building-packages>`__.

   * Building PyTorch: Build a compatible PyTorch version against ROCm wheels.
     See the `PyTorch build instructions
     <https://github.com/ROCm/TheRock/tree/main/external-builds/pytorch#build-instructions>`__.

Platform-specific setup
=======================

ManyLinux
---------

On Linux, it's recommended to build with ManyLinux to produce binaries that are
portable across Ubuntu and other Linux distributions. To learn more about what
a ROCm ManyLinux build entails, see `ManyLinux builds
<https://github.com/ROCm/TheRock/blob/main/docs/design/manylinux_builds.md>`__.
Refer to `ManyLinux x86_64
<https://github.com/ROCm/TheRock/blob/main/docs/environment_setup_guide.md#manylinux-x86-64>`__
in the environment setup guide.

Ubuntu 24.04
------------

TheRock provides detailed instructions and scripts for preparing an Ubuntu
24.04 system, including installing necessary packages via apt.
Refer to `Setup — Ubuntu 24.04 <https://github.com/ROCm/TheRock?tab=readme-ov-file#setup---ubuntu-2404>`__
in the TheRock repository for guidance.

Windows 11
----------

For setup instructions on Windows 11 using Visual Studio 2022, see
`Setup — Windows 11
<https://github.com/ROCm/TheRock?tab=readme-ov-file#setup---windows-11-vs-2022>`__
in the TheRock repository.

   For details on supported configurations, known issues, and other
   Windows-specific considerations, review the `Windows support
   <https://github.com/ROCm/TheRock/blob/main/docs/development/windows_support.md>`__
   documentation.
