Thanks for your advice. It worked after I add the "--upstream-libs" parameter. I really appreciate your help.

My DPDK build environment is "CentOS7.0 + kernel 3.10.0-229.el7.x86_64". I have download the OFED 4.2 and use the following command to install: ./mlnxofedinstall --skip-distro-check --dpdk --add-kernel-support /etc/init.d/openibd restart However, I still met error while I am compiling DPDK-17.11. The error information is : In file included from /home/wangyong/dpdk-17.11/drivers/net/mlx4/mlx4.c:71:0: /home/wangyong/dpdk-17.11/drivers/net/mlx4/mlx4_rxtx.h:44:31: fatal error: infiniband/mlx4dv.h: No such file or directory #include <infiniband/mlx4dv.h> ^ compilation terminated. make[6]: *** [mlx4.o] Error 1 make[5]: *** [mlx4] Error 2 make[4]: *** [net] Error 2 make[3]: *** [drivers] Error 2 make[2]: *** [all] Error 2 make[1]: *** [pre_install] Error 2 make: *** [install] Error 2 I checked the "/usr/include/infiniband" directory and I couldn't find the mlx4dv.h file. Are there any other configurations or steps required? Or the kernel version of linux can't be 3.10 ? ------------------origin------------------ from：[email protected] <[email protected]> to：Nelio Laranjeiro <[email protected]> cc：[email protected] <[email protected]> date：2018年01月05日 16:03 subject：Re: [dpdk-users] Compile DPDK 17.11 with Mellanox NIC support Hi Nelio, Thanks for the prompt reply and guidance! My OFED version was 4.1, that's why I was unable to build DPDK 17.11. With OFED 4.2 everything works on my kernel (v4.4)! I have one more question: What is the suggested OFED version in order to have a fully featured NIC with all the DPDK classification/offloading capabilities? My NICs are 100G ConnectX-4 (dual and single port).
