undefined reference to `uuid_is_null'
So the thing is that, when uuid support is detected, libblkid.a wants to
use it, mount wants to link against it and it is being sucked in.
I encountered the same problem when building 2.14 and 2.14-rc2
2.13 did not complain about missing uuid references.
that use it forget to link against it. Not sure if the patch below is
[...]
+mount_LDADD = $(LDADD_common) -luuid
+umount_LDADD = $(LDADD_common) -luuid
+swapon_LDADD = $(LDADD_common) -luuid
Why do you think that mount,umount and swapon use stuff from libuuid?
The libuuid is required by mkswap only.
Yup, side effect, see above. I'll invent a better patch ...
I fixed it by building like this:
# BLKID_LIBS="-lblkid -luuid" ./configure --prefix=/usr
# make -C mount mount umount
But surely there must be a better way (some autoconf/automake magic ?).
