Please note this is a third party package maintained by Mellanox, therefore this mailing list is not the right place to discuss related errors, unless they can be reproduced with a version downloaded from dpdk.org. > Then, I stumbled upon a compilation problem in the mlx4 module. > The compiler's output is as follows: > > == Build drivers/net/mlx4 > CC mlx4.o > In file included from /usr/include/linux/if.h:31:0, > from /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:57: > /usr/include/linux/hdlc/ioctl.h:73:14: error: ‘IFNAMSIZ’ undeclared here > (not in a function) > char master[IFNAMSIZ]; /* Name of master FRAD device */ > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:612:53: error: ‘struct > ifreq’ declared inside parameter list [-Werror] > priv_ifreq(const struct priv *priv, int req, struct ifreq *ifr) > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:612:53: error: its scope is > only this definition or declaration, which is probably not what you want > [-Werror] > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function ‘priv_ifreq’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:619:32: error: dereferencing > pointer to incomplete type ‘struct ifreq’ > if (priv_get_ifname(priv, &ifr->ifr_name) == 0) > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function ‘rxq_setup’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:3735:29: error: unused > parameter ‘inactive’ [-Werror=unused-parameter] > unsigned int socket, int inactive, const struct rte_eth_rxconf *conf, > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function > ‘mlx4_link_update_unlocked’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4712:15: error: storage size > of ‘ifr’ isn’t known > struct ifreq ifr; > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4724:43: error: ‘IFF_UP’ > undeclared (first use in this function) > dev_link.link_status = ((ifr.ifr_flags & IFF_UP) && > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4724:43: note: each > undeclared identifier is reported only once for each function it appears in > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4725:22: error: > ‘IFF_RUNNING’ undeclared (first use in this function) > (ifr.ifr_flags & IFF_RUNNING)); > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4712:15: error: unused > variable ‘ifr’ [-Werror=unused-variable] > struct ifreq ifr; > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function > ‘mlx4_dev_get_flow_ctrl’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4880:15: error: storage size > of ‘ifr’ isn’t known > struct ifreq ifr; > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4880:15: error: unused > variable ‘ifr’ [-Werror=unused-variable] > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function > ‘mlx4_dev_set_flow_ctrl’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4930:15: error: storage size > of ‘ifr’ isn’t known > struct ifreq ifr; > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:4930:15: error: unused > variable ‘ifr’ [-Werror=unused-variable] > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function ‘priv_get_mac’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:5184:15: error: storage size > of ‘request’ isn’t known > struct ifreq request; > ^ > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:5184:15: error: unused > variable ‘request’ [-Werror=unused-variable] > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function > ‘mlx4_pci_devinit’: > /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:5725:25: error: ‘IFF_UP’ > undeclared (first use in this function) > priv_set_flags(priv, ~IFF_UP, IFF_UP); > ^ > cc1: all warnings being treated as errors > /opt/MLNX_DPDK_2.2_2.7/mk/internal/rte.compile-pre.mk:126: recipe for > target 'mlx4.o' failed > > Iwould appreciate any suggestions and guidance. Well fortunately these errors are also present in v2.2.0 and should have been addressed since v16.07 by the following commit: http://dpdk.org/browse/dpdk/commit/?id=d06c608c013c36711e7a693b3fece68a93ae4369 You can either upgrade to v16.07, back-port this commit yourself or wait for an update from Mellanox. -- Adrien Mazarguil 6WIND
