Hi
I am not knowledgeable on gcc advanced syntax but I worked in C/C++
before and gcc 4.8.5 on CentOS 4.6 croaks when seeing the below in
"lib/netdev-dpdk.c" and then many other errors
Build first dpdk 18.11 w/o error then attempted to build ovs based on
http://docs.openvswitch.org/en/latest/intro/install/dpdk/ and
http://docs.openvswitch.org/en/latest/intro/install/general/
My gcc is 4.8.5, libtool 2.4.6 and doing the make after a ./configure
--with-dpdk=<DPDK build folder>
What is missing please??? It seems simply a syntax not supported by the
compiler
Here is the culprit (or one of them)
static const struct rte_eth_conf port_conf = {
.rxmode = {
.mq_mode = ETH_MQ_RX_RSS,
.split_hdr_size = 0,
.header_split = 0, /* Header Split disabled */
.hw_ip_checksum = 0, /* IP checksum offload disabled */
.hw_vlan_filter = 0, /* VLAN filtering disabled */
.jumbo_frame = 0, /* Jumbo Frame Support disabled */
.hw_strip_crc = 0,
},
.rx_adv_conf = {
.rss_conf = {
.rss_key = NULL,
.rss_hf = ETH_RSS_IP | ETH_RSS_UDP | ETH_RSS_TCP,
},
},
.txmode = {
.mq_mode = ETH_MQ_TX_NONE,
},
};
make
... all fine till below ...
