Subject: [PATCH] Fix packed-not-aligned error on GCC 8
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
When building with GCC 8, there are several errors regarding packed-not-aligned.
|
||
|
||
./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]
|
||
|
||
This patch fixes the build error by cleaning up the ambiguity of placing
|
||
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
|
||
grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
|
||
has to be packed, to ensure the structure is bit-to-bit mapped to the format
|
||
laid on disk. I think we could blame to copy and paste error here for the
|
||
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as
|
||
the name suggests. :)
