From ea134caa08ca86689a56665f30bebeb38c5cd1ab Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Fri, 8 Jun 2018 10:39:09 +0200 Subject: [PATCH] typedefs: add QJSON Since commit 83ee768d6247b, we now have two places that define the QJSON type: $ git grep 'typedef struct QJSON QJSON' include/migration/vmstate.h:typedef struct QJSON QJSON; migration/qjson.h:typedef struct QJSON QJSON; This breaks docker-test-build@centos6: In file included from /tmp/qemu-test/src/migration/savevm.c:59: /tmp/qemu-test/src/migration/qjson.h:16: error: redefinition of typedef 'QJSON' /tmp/qemu-test/src/include/migration/vmstate.h:30: note: previous declaration of 'QJSON' was here make: *** [migration/savevm.o] Error 1 This happens because CentOS 6 has an old GCC 4.4.7. Even if redefining a typedef with the same type is permitted since GCC 4.6, unless -pedantic is passed, we don't really need to do that on purpose. Let's have a single definition in instead.
