# OpenHPC-provided Go toolchain, built from upstream source. It exists for
# distributions whose packaged Go is too old to build current OpenHPC Go
# components (notably Warewulf): openEuler ships Go 1.21 by default and 1.24 at
# newest, below Warewulf's go.mod requirement. Enterprise Linux ships a current
# go-toolset, so this package is built and shipped only for openEuler.

# Keep this deliberately separate from the distro Go: the package is named
# golang-ohpc and provides ONLY that capability. Auto-generated provides from
# the Go tree are suppressed below (__provides_exclude_from), so this never
# emits a bare "golang"/"go" that could satisfy or collide with the system
# package. State the capability explicitly for consumers (e.g. warewulf's
# openEuler build BuildRequires golang-ohpc and loads it as a module).

%description
The Go programming language toolchain (compiler, linker, standard library and
tools), packaged for OpenHPC under %{OHPC_HOME} with an environment module.
Provided for distributions whose native Go is too old to build current OpenHPC
Go components (notably Warewulf).
