From 755d97d38c62244e43a29b3d3426448003d1323b Mon Sep 17 00:00:00 2001 From: Thomas Haller Date: Mon, 2 Nov 2020 16:25:53 +0100 Subject: [PATCH] libnm/tests: include "nm-default.h" for "libnm-core/tests/nm-core-tests-enum-types.c" With glib2-2.67.0-1.fc34.x86_64.rpm, clang-11.0.0-2.fc34.x86_64.rpm, the generated code emits a compiler warning: libnm-core/tests/nm-core-tests-enum-types.c:17:7: error: passing 'typeof (*(&g_define_type_id__volatile)) *' (aka 'volatile unsigned long *') to parameter of type 'gsize *' (aka 'unsigned long *') discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] if (g_once_init_enter (&g_define_type_id__volatile)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gthread.h:260:7: note: expanded from macro 'g_once_init_enter' (!g_atomic_pointer_get (location) && \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gatomic.h:112:38: note: expanded from macro 'g_atomic_pointer_get' __atomic_load (gapg_temp_atomic, &gapg_temp_newval, __ATOMIC_SEQ_CST); \ ^~~~~~~~~~~~~~~~~ libnm-core/tests/nm-core-tests-enum-types.c:40:7: error: passing 'typeof (*(&g_define_type_id__volatile)) *' (aka 'volatile unsigned long *') to parameter of type 'gsize *' (aka 'unsigned long *') discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] if (g_once_init_enter (&g_define_type_id__volatile)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gthread.h:260:7: note: expanded from macro 'g_once_init_enter' (!g_atomic_pointer_get (location) && \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gatomic.h:112:38: note: expanded from macro 'g_atomic_pointer_get' __atomic_load (gapg_temp_atomic, &gapg_temp_newval, __ATOMIC_SEQ_CST); \ ^~~~~~~~~~~~~~~~~ libnm-core/tests/nm-core-tests-enum-types.c:63:7: error: passing 'typeof (*(&g_define_type_id__volatile)) *' (aka 'volatile unsigned long *') to parameter of type 'gsize *' (aka 'unsigned long *') discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] if (g_once_init_enter (&g_define_type_id__volatile)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gthread.h:260:7: note: expanded from macro 'g_once_init_enter' (!g_atomic_pointer_get (location) && \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/glib-2.0/glib/gatomic.h:112:38: note: expanded from macro 'g_atomic_pointer_get' __atomic_load (gapg_temp_atomic, &gapg_temp_newval, __ATOMIC_SEQ_CST); \ ^~~~~~~~~~~~~~~~~ We could pass "-Wincompatible-pointer-types-discards-qualifiers" as CFLAGS when building this file. However, we have a workaround in our "nm-glib-aux/nm-glib.h", so we can instead include "nm-default.h". At first glance, that might look like the less preferable solution. However, this file is only there for unit tests, and we also include "nm-default.h" for other sources that are generated with "glib-mkenums". So, doing it also for our tests becomes the preferable solution. --- Makefile.am | 1 + 1 file changed, 1 insertion(+) diff --git a/Makefile.am b/Makefile.am index e95cfddac..6e5b9446a 100644 --- a/Makefile.am +++ b/Makefile.am @@ -1220,6 +1220,7 @@ GLIB_GENERATED += \ libnm-core/tests/nm-core-tests-enum-types.h \ libnm-core/tests/nm-core-tests-enum-types.c nm_core_tests_enum_types_sources = libnm-core/tests/test-general-enums.h +nm_core_tests_enum_types_MKENUMS_C_FLAGS = --fhead '\#include "nm-default.h"\n' libnm-core/tests/nm-core-tests-enum-types.h.stamp: libnm-core/tests/.dirstamp libnm-core/tests/nm-core-tests-enum-types.c.stamp: libnm-core/tests/.dirstamp
