Clang gives me the following errors:
../ofproto/ofproto-dpif.c:4792:32: error: unknown warning group
'-Wmaybe-uninitialized', ignored [-Werror,-Wunknown-pragmas]
../ofproto/ofproto-dpif.c:4814:33: error: initializing 'struct
ofputil_group_props *' with an expression of type 'const struct
ofputil_group_props *' discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
"sparse" gives me the following errors:
../ofproto/ofproto-dpif.c:4742:24: error: Variable length array is used.
../ofproto/ofproto-dpif.c:4814:42: error: incorrect type in initializer
(different modifiers)
../ofproto/ofproto-dpif.c:4814:42: expected struct ofputil_group_props
*props
../ofproto/ofproto-dpif.c:4814:42: got struct ofputil_group_props const
*<noident>
Thanks,
Ben.
