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?

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
