Avoid that building against glibc >= 2.25 triggers the following compiler warning: lopart.c: In function 'is_loop_device': lopart.c:93:13: warning: In the GNU C Library, "major" is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan to remove this soon. To use "major", include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro "major", you should undefine it after including <sys/types.h>. major(statbuf.st_rdev) == loopmajor); Signed-off-by: Bart Van Assche <bart.vanassche@xxxxxxxxxxx> --- kpartx/Makefile | 4 ++++ kpartx/sysmacros.h | 6 ++++++ 2 files changed, 10 insertions(+) diff --git a/kpartx/Makefile b/kpartx/Makefile index 9441a2ba..2d2a249e 100644 --- a/kpartx/Makefile +++ b/kpartx/Makefile @@ -10,6 +10,10 @@ LIBDEPS += -ldevmapper ifneq ($(call check_func,dm_task_set_cookie,/usr/include/libdevmapper.h),0) CFLAGS += -DLIBDM_API_COOKIE endif +ifneq ($(call check_func,major,/usr/include/sys/sysmacros.h),0) + CFLAGS += -DHAVE_SYS_SYSMACROS_H +endif + OBJS = bsd.o dos.o kpartx.o solaris.o unixware.o dasd.o sun.o \ gpt.o mac.o ps3.o crc32.o lopart.o xstrncpy.o devmapper.o diff --git a/kpartx/sysmacros.h b/kpartx/sysmacros.h index 171b33d4..dc5077ec 100644 --- a/kpartx/sysmacros.h +++ b/kpartx/sysmacros.h @@ -1,5 +1,10 @@ /* versions to be used with > 16-bit dev_t - leave unused for now */ +#ifdef HAVE_SYS_SYSMACROS_H +#include <sys/sysmacros.h> +#else +#include <sys/types.h> + #ifndef major #define major(dev) ((dev) >> 8) #endif @@ -7,3 +12,4 @@ #ifndef minor #define minor(dev) ((dev) & 0xff) #endif +#endif -- 2.12.2 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
