From 705601781b6ab4f3035719ddaf1e442f4a5e8737 Mon Sep 17 00:00:00 2001 From: Steve Langasek Date: Wed, 20 Mar 2024 17:58:40 +0100 Subject: v4l2: Unset _TIME_BITS in addition to _FILE_OFFSET_BITS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit libcamera fails to build from source in Debian/Ubuntu on 32-bit architectures under 64-bit time_t (to avoid the 'year 2038 problem'), because its v4l2 module legitimately un-sets _FILE_OFFSET_BITS for building but this is not allowed without also unsetting _TIME_BITS. Having verified that nothing in this module is sensitive to 64-bit time_t (none of the functions it intercepts handle time), we also unset _TIME_BITS to allow this to build as before.
