+# Note from https://github.com/wlynxg/anet?tab=readme-ov-file#how-to-build-with-go-1230-or-later
+# The `anet` library internally relies on `//go:linkname` directive. Since the usage of `//go:linkname` has been
+# restricted since Go 1.23.0 ([Go 1.23 Release Notes](https://tip.golang.org/doc/go1.23#linker)), it is
+# necessary to specify the `-checklinkname=0` linker flag when building the `anet` package with Go 1.23.0 or later.
+# Without this flag, the following linker error will occur:
+# ```
+# link: github.com/wlynxg/anet: invalid reference to net.zoneCache
+# ```
