h5cpp Conan Recipe

This repository contains a Conan recipe for packaging h5cpp, a modern C++ wrapper for the HDF5 C library.

Creating a New Conan Package Release

When a new h5cpp release is published on GitHub Releases:

1. Update conandata.yml

Update the version entry with the new URL and its SHA256 checksum.

To calculate the SHA256:

curl -L https://github.com/ess-dmsc/h5cpp/archive/refs/tags/<release_number>.tar.gz | sha256sum

2. Update the Version in conanfile.py

Modify the version = "<new_version>" field accordingly.

3. Create a Merge Request

Submit your changes via a merge request. This will trigger a CI pipeline to test the package creation. Note: The package won't be uploaded to the remote yet.

Once the MR is merged, a second pipeline will:

• Create the package
• Upload it to the ECDC Conan remote
• Done!

Testing Package Creation Locally

If you'd like to verify the recipe locally:

conan config install https://github.com/ess-dmsc/conan-configuration.git
git clone git@gitlab.esss.lu.se:ecdc/ess-dmsc/conan-h5cpp.git
cd conan-h5cpp

Then run:

conan create . ess-dmsc/testing -pr=linux_x86_64_gcc11 --build=missing

---

Verifying the Package

To inspect the generated package:

conan search h5cpp
conan info h5cpp/0.7.1@ess-dmsc/testing -pr=linux_x86_64_gcc11

---

Using the Docker Build Environment

Use the pre-built Docker image for a clean build environment:

docker run --rm -it \
  -v "$(pwd)":/project \
  -w /project \
  registry.esss.lu.se/ecdc/ess-dmsc/docker-almalinux9-conan:1.2.0 \
  bash

Inside the container, use Conan as usual:

conan create . ess-dmsc/testing -pr=linux_x86_64_gcc11 --build=missing
