... tap-ctl-allocate.c: In function 'tap_ctl_make_device': tap-ctl-allocate.c:114:13: error: In the GNU C Library, "makedev" 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 "makedev", include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro "makedev", you should undefine it after including <sys/types.h>. [-Werror] err = mknod(devname, perm, makedev(major, minor)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
