From 7a8f8974ecd729cd50ce59b9ba4a6bf05614c808 Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Sun, 30 Jun 2024 10:13:25 +0200 Subject: [PATCH] rust: work around `bindgen` 0.69.0 issue `bindgen` 0.69.0 contains a bug: `--version` does not work without providing a header [1]: error: the following required arguments were not provided:
Usage: bindgen
-- ... Thus, in preparation for supporting several `bindgen` versions, work around the issue by passing a dummy argument. Include a comment so that we can remove the workaround in the future.
