This page explains how to integrate your software into the Fuchsia project as a prebuilt CIPD package.
To publish your prebuilt package to CIPD, see the following guidelines:
After publishing your prebuilt package to CIDP, update the Fuchsia Jiri manifests to ensure that the content of the package is available to Fuchsia's continuous integration (CI) and Fuchsia developers.
If your prebuilt package contains ELF binaries (whether inside a FAR or not), they need to be stripped. Additionally, for Fuchsia ELF binaries, you need to generate and upload a companion symbols package to support symbolization and debugging.
Choose a CIPD package path
Each CIPD package has a distinctive path in the CIPD store. The naming convention of this path depends on whether the prebuilts are generated (or maintained) by the Fuchsia project.
A CIPD package contributed by an external project
For a prebuilt CIPD package contributed by an external team or project, use the following CIPD path naming convention:
<CIPD_TARGET_ARCHITECTURE> is a CIPD-compatible CPU architecture
name (for instance,
amd64 for 64-bit Intel binaries, not
See the following examples:
A CIPD package generated by the Fuchsia project
For prebuilt packages that are generated or maintained by the Fuchsia project, use the following CIPD path naming conventions:
fuchsia/as the root project directory for all prebuilt packages.
For prebuilts generated from third-party open source projects, use a path under
fuchsia/third_party/ninja/contains packages for prebuilt binaries of the Ninja build tool, while
fuchsia/sdk/corecontains packages corresponding to Fuchsia IDK archives generated by the Fuchsia project.
For the last directory entry of host prebuilts, use the following convention:
<CIPD_OS>is a CIPD-compatible OS name.
<CIPD_HOST_ARCHITECTURE>a CIPD-compatible CPU architecture name.
fuchsia/third_party/clang/mac-amd64is the path used for the CIPD package that contains the 64-bit Intel OS X Clang toolchain binaries.
Fuchsia ELF prebuilts need to use a path that ends with the following:
<ARCH>is a Fuchsia-compatible CPU architecture name.
In the case of 64-bit Intel binaries,
amd64is only used for host prebuilts while
x64is only used for Fuchsia ELF prebuilts.
fuchsia/third_party/swiftshader/arch/x64is the path used for the SwitfShader-based Vulkan ICD/driver that is built for Fuchsia.
Set CIPD package versioning
Fuchsia developers need to be able to identify which source code is used to generate each CIPD package instance.
To identify the source of prebuilt packages, tag each revision with a version identifier in the form of:
In addition to specifying
version, if available (for example, building
third-party open source projects), include a Git commit hash:
git_revision tag identifies the exact Git commit of the source tree used
to build the binaries.
If several revisions are built from the same Git commit hash (for example,
the first instance was mistakenly built in debug, instead of release mode),
you can use a suffix separated with a dash (
-), as in
git_revision:<GIT_COMMIT_HASH>-2, for the new revision's tag.
Upload a CIPD package
Manually uploading a new CIPD package revision requires you to be authentified
cipd auth-login, then run the
cipd create command. Example instructions
are available from
this CIPD page.
cipd.yaml file is strongly recommended. A good practice is to
auto-generate this file from your rebuild script and include uploading
instructions in a comment, as shown in the following pseudo-example:
# This file was auto-generated by build-project-fuchsia-package.sh # For more information, see http://myproject.url/docs/fuchsia/ # # To upload the files in this CIPD package do: # # TAG=git_revision:cd13435a975057b0ad0b72636f6c8323113c9c8b # VERSION=version:22.0.773.345 # cipd create -pkg-file cipd.yaml -tag $TAG -tag $VERSION # package: myproject/fuchsia/mypackage-arm64 description: mypackage's Fuchsia binaries from myproject. data: - file: LICENSE # or NOTICE(.txt) - file: libpackage.so
Don't forget to also upload a companion symbols package if your package contains Fuchsia ELF binaries.
