Release Instructions

Since all toolchains share the same repository, release versions many not contain artifacts for all toolchains.

These steps must be repeated for each toolchain that is part of the overall release.

<toolchain> is a placeholder for the name of the toolchain you are building.

Changing Version

  • Check mix deps for version bumps and ensure that they are pushed and pointed to Hex (nerves_toolchain_ctng/nerves_toolchain | nerves)
  • Bump version in related files listed below
  • Commit changes
  • Tag repository

Building Artifacts

Artifacts need to be produced for all host / target combinations for the toolchains being released.

  • Linux (On Linux): nerves_toolchain_ctng/build.sh <toolchain>
  • macOS (On macOS): nerves_toolchain_ctng/build.sh <toolchain>
