From 875df03b221ef6a67f175f1f283ea5598f717da5 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 16 Apr 2021 14:55:39 +0100 Subject: osdep: protect qemu/osdep.h with extern "C" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit System headers may include templates if compiled with a C++ compiler, which cause the compiler to complain if qemu/osdep.h is included within a C++ source file's 'extern "C"' block. Add an 'extern "C"' block directly to qemu/osdep.h, so that system headers can be kept out of it. There is a stray declaration early in qemu/osdep.h, which needs to be special cased. Add a definition in qemu/compiler.h to make it look nice. config-host.h, CONFIG_TARGET, exec/poison.h and qemu/compiler.h are included outside the 'extern "C"' block; that is not an issue because they consist entirely of preprocessor directives. This allows us to move the include of osdep.h in our two C++ source files outside the extern "C" block they were previously using for it, which in turn means that they compile successfully against newer versions of glib which insist that glib.h is *not* inside an extern "C" block.
