I also have this problem in centos.
I try it, remove "-std=gnu99" for gcc is worked.
[root@vNetCI ~]# gcc lgs.c
[root@vNetCI ~]#
[root@vNetCI ~]# gcc -std=gnu99 lgs.c
lgs.c:9:15: error: initializer element is not constant
= (struct eth_addr) { { .ea = { 0x00, 0x23, 0x20, 0x00, 0x00,
0x01 } } };
this is my code:
struct eth_addr {
union {
char ea[6];
int be16[3];
};
};
static const struct eth_addr eth_addr_bfd
= (struct eth_addr) { { .ea = { 0x00, 0x23, 0x20, 0x00, 0x00, 0x01
} } };
Hi Ben,
I faced following error while compiling OVS master on Ubuntu. I am not sure, if
I am missing some compiler directive.
./include/openvswitch/types.h:173:41: error: initializer element is not constant
#define ETH_ADDR_C(A,B,C,D,E,F) (struct eth_addr) \
^
lib/packets.h:179:7: note: in expansion of macro 'ETH_ADDR_C'
= ETH_ADDR_C(ff,ff,ff,ff,ff,ff);
^
By removing the typecast from types.h file worked.
--old--
#define ETH_ADDR_C(A,B,C,D,E,F) (struct eth_addr) \
{ { .ea = { 0x##A, 0x##B, 0x##C, 0x##D, 0x##E, 0x##F } } }
--new--
#define ETH_ADDR_C(A,B,C,D,E,F) \
{ { .ea = { 0x##A, 0x##B, 0x##C, 0x##D, 0x##E, 0x##F } } }
Warm Regards,
Vishal

These macros expand to constants of type struct eth_addr and struct
eth_addr64, respectively, and make it more convenient to initialize
or assign to an Ethernet address object.

Thanks, applied to master.
