build-native.yml

name: Build native

# Produces the diffengine_viewer binaries committed under
# src/DiffEngineViewer.{Linux,Mac}/runtimes/{rid}/native, in the head that loads them. There is no
# Windows equivalent: that head renders with WinForms.
#
# They are committed rather than built during a normal build so that a plain
# `dotnet build src --configuration Release` produces a shippable package on any machine, and
# contributors never need a C++ toolchain. Run this whenever native/ changes.
#
# The work is PlatformHeads' build-native workflow, which this one was moved into so that
# BuildMonitor, built the same way, runs it too: the Linux library built in a manylinux_2_28
# container and checked for the glibc it needs and the libraries it records as needed, the
# universal dylib, and the pull request with the binaries. BuildMonitor had a copy of it, and
# three fixes made here were waiting to be found again there.
# The tag is the one native/CMakeLists.txt fetches and Directory.Packages.props names.
