From 9b5182d4781bcd6fb37a4030faf325965fde3e93 Mon Sep 17 00:00:00 2001 From: Alexander Kanavin Date: Thu, 28 Nov 2024 20:32:17 +0100 Subject: [PATCH] meson: correct check for existence of two preprocessor defines sizeof is meant for *types*, and in case of cross compiling the test program produced by it has incorrect syntax __NR_keyctl something; and will always fail to compile. * meson.build: Use cc.get_define() instead of cc.sizeof() to check for preprocessor symbols.
