# Since 1.38 the kvm2 driver is linked into the minikube binary itself
# (pkg/minikube/registry/drvs/kvm2) and reaches libvirt through dlopen: the
# Makefile builds with -tags libvirt_dlopen, which selects "#cgo LDFLAGS: -ldl"
# instead of "#cgo pkg-config: libvirt" in libvirt.org/go/libvirt.  Nothing
# libvirt-related is needed to compile, so the dependency is runtime-only --
# without it dlopen("libvirt.so.0") fails and only the kvm2 driver is lost.
RDEPEND="libvirt? ( app-emulation/libvirt:=[qemu] )"

# go.mod says "go 1.25.0"; the eclass only floors go at its own default, and
# portage raises a QA notice for the gap.  dev-go/go-bindata is gone from here:
# the Makefile stopped invoking it, and nothing outside a comment and one
# skip-path regex mentions bindata any more.
