conan-center-index (ownCloud)

ownCloud's copy of Conan Center Index, carrying the Conan recipes that the ownCloud Desktop and Kiteworks Desktop clients build their C++ dependencies from. The packages built here were published to an ownCloud Artifactory Conan remote for the desktop builds to consume - that remote no longer resolves and its replacement has not been decided, so today this repository is the recipe source and nothing more. See "Building locally" below.

This is a detached copy, not a GitHub fork. It has no upstream parent, so GitHub's "Sync fork" button and cross-repository compare do not work on it. Upstream is tracked by adding it as an ordinary git remote.

Almost everything under recipes/ is upstream content that is carried rather than maintained here. The intended local delta is four recipes with no upstream counterpart:

Recipe	Versions
kdsingleapplication	1.2.0, 1.1.0
libregraphapi	1.0.4
qtkeychain	0.15.0
sparkle	2.7.0 (macOS only)

Plus the ownCloud-specific plumbing: conanfile.py, .config/global.conf and .github/profiles/.

Layout

• conanfile.py - the root aggregator (GlobalDependencyMirror). Not a package recipe: it is the list of what gets built and uploaded, and the single place where the desktop clients' dependency versions and Qt options are pinned.
• recipes/<name>/config.yml - maps each version of a package to a recipe folder, then recipes/<name>/<folder>/ holds conanfile.py, conandata.yml, optional patches/ and a test_package/.
• .config/global.conf - Conan client configuration.
• .github/profiles/ - one Conan profile per target platform.
• docs/ - upstream's recipe authoring documentation.

Building locally

This repository has no CI. Packages are built and published by hand with the commands below, which were previously carried by .github/workflows/conan.yml.

The Artifactory remote below does not currently exist. artifactory.owncloud-demo.com does not resolve (NXDOMAIN, checked 2026-09-10), so the oc remote cannot be added, logged into, pulled from or uploaded to. The URL is recorded here because it is the one the build used; the replacement has not been decided. Until it is, only the local remote works, which is enough to build everything from source but means no shared binary cache and no publishing.

One-time setup

conan config install ./.config/global.conf

# `local` must be added before `oc` so that recipes from this checkout take
# precedence over the ones already published to Artifactory.
conan remote add local .
conan remote remove conancenter
conan remote add oc https://artifactory.owncloud-demo.com/artifactory/api/conan/conan-local
conan remote login oc "$CONAN_USER" -p "$CONAN_PASSWORD"

conan remote list
conan profile show

See the Conan documentation on building binaries from a private conan-center-index fork for the background on this layout.

On Windows, set CONAN_HOME to a short path first to stay clear of the path length limit:

$Env:CONAN_HOME = "D:\a\b\"

Build

Pick a profile from .github/profiles/ and a build type (Release, RelWithDebInfo, Debug):

conan install . --profile=.github/profiles/macos-latest-armv8.conanprofile \
  -s build_type=Release --build=missing

To cross-compile, pass the host and build profiles separately:

conan install . --profile:host=.github/profiles/macos-latest-x86_64.conanprofile \
  --profile:build=.github/profiles/macos-latest-armv8.conanprofile \
  -s build_type=Release --build=missing

Use conan graph info . --profile=<profile> -s build_type=<type> to check that the dependencies in conanfile.py resolve before starting an expensive build.

Publish

Blocked until the Artifactory remote exists again (see the note above).

conan upload -r oc "*" -c

Resyncing with upstream

master requires linear history and the repository squash-merges, so do not resync with git merge - a merge commit cannot be pushed. Replace the shared tree instead:

git remote add upstream https://github.com/conan-io/conan-center-index.git
git fetch upstream master
git switch -c chore/sync-upstream-recipes master

# set the ownCloud-only recipes aside
mkdir -p "$TMPDIR/oc-recipes"
cp -R recipes/kdsingleapplication recipes/libregraphapi \
      recipes/qtkeychain recipes/sparkle "$TMPDIR/oc-recipes/"

# take upstream verbatim for everything shared
rm -rf recipes docs assets
git checkout upstream/master -- recipes docs assets .editorconfig .gitattributes LICENSE

# restore the ownCloud-only recipes
cp -R "$TMPDIR/oc-recipes/." recipes/
git add -A

Do not take README.md, .gitignore, .config/, conanfile.py, .github/profiles/ or the community health files from upstream, and leave CONTRIBUTING.md, .github/ISSUE_TEMPLATE/, .github/PULL_REQUEST_TEMPLATE.md and .github/workflows/stale.yml deleted.

Then check the delta is exactly what it should be:

git diff --stat upstream/master -- recipes docs assets

This must show only the four ownCloud recipe trees as additions. Anything else means an upstream recipe is still being patched locally, which should be sent upstream instead.

Upstream keeps only the newest patch release per minor, so a resync routinely deletes the exact versions conanfile.py pins. Re-check every requires and tool_requires against the relevant recipes/<name>/config.yml afterwards and bump as needed. Note that cmake must stay below 4 while extra-cmake-modules pins cmake/[>=3.16 <4].

Contributing

Changes to an upstream recipe belong upstream; see upstream's CONTRIBUTING.md and the docs/ directory here for how recipes are written and reviewed. Fixes merged upstream arrive here on the next resync.

Changes to the four ownCloud-only recipes, to conanfile.py, or to the plumbing are made here by pull request against master. Commits must be signed and DCO signed-off (git commit -S -s), and commit subjects and PR titles follow Conventional Commits.
