Currently, the kerneldoc Sphinx plugin doesn't honour the --enable-werror configure option, so its warnings are never fatal. This is because although we do pass sphinx-build the -W switch, the warnings from kerneldoc are produced by the scripts/kernel-doc script directly and don't go through Sphinx's "emit a warning" function. When --enable-werror is in effect, pass sphinx-build an extra argument -Dkerneldoc_werror=1. The kerneldoc plugin can then use this to determine whether it should be passing the kernel-doc script -Werror. We do this because there is no documented mechanism for a Sphinx plugin to determine whether sphinx-build was passed -W or not; if one is provided then we can switch to that at a later date: https://github.com/sphinx-doc/sphinx/issues/11239 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Thomas Huth <thuth@redhat.com> Message-Id: <20230314114431.1096972-1-peter.maydell@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu>
