From 19652e5028e92f8eb7ca989d754c1e394216fbb6 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 30 May 2021 02:48:02 +0300 Subject: gst: Fix compilation warning with GLib >= 2.62 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GLib 2.62 has deprecated g_memdup(), which is used inline in GStreamer's gstbytereader.h header. This results in a compilation warning: In file included from /usr/include/gstreamer-1.0/gst/base/base.h:35, from ../../src/gstreamer/gstlibcamerasrc.cpp:39: /usr/include/gstreamer-1.0/gst/base/gstbytereader.h: In function ‘guint8* gst_byte_reader_dup_data_unchecked(GstByteReader*, guint)’: /usr/include/gstreamer-1.0/gst/base/gstbytereader.h:365:41: error: ‘void* g_memdup(gconstpointer, guint)’ is deprecated: Use 'g_memdup2' instead [-Werror=deprecated-declarations] 365 | return (guint8 *) g_memdup (data, size); GLib has a mechanism to silence warnings introduced in newer versions, to allow compilation without warnings on multiple versions of the library. This is done by setting the GLIB_VERSION_MIN_REQUIRED macro to the minimum GLib version required. As we depend on GStreamer >= 1.14, set the minimum GLib version to 2.40.
