I've tried to make the driver from 2.7.29 sources also - result is the same.

With older kernels like 4.4.179 the driver could be compiled.

Hello amindomao, Thank you for posting in Intel Ethernet Communities. For me to further check this issue. Can you provide the following information about your system: 1. What is the brand and model of your NIC card? 2. What is your OS? 3. What is the model of your system? Best regards, Michael L. Intel Customer Support Under Contract to Intel Corporation

[amindomao]

1. I have not got any NIC yet. I'm just trying to get recent drivers for the NIC I'm going to buy.
2. My OS is Centos with mainline kernel from community approved repository - ELRepo.
3. System is Dell R620.

[amindomao]

I've tried different versions of gcc also, with no success.

Hello amindomao, I am sorry as I need to further clarify your inquiry. Are you trying to program a driver using 5.0.10 or you are just looking for the latest generic driver? As for generic driver, we only have one download site which is: https://downloadcenter.intel.com/ If you have questions, please let us know. Best regards, Michael L.

Hello!

I have Linux OS, CENTOS 7.5 exactly. I'm using a main line linux kernel version 5.0.10 and trying to build intel xl710 driver for my OS. I've tried driver versions 2.7.26 and i40e-2.7.29 - the result is the error during building process, which part is in my first post.

[amindomao]

Look at the screenshot please.

Hello amindomao, Are you installing the driver or programming a driver? Can you explain further when you say you are trying to build intel xl710 driver. If you have questions, please let us know. Best regards, Michael L. Intel Customer Support Under Contract to Intel Corporation

[amindomao]

Ok. Lets try in another way.

I've downloaded the driver I need ( look at the above screenshot ); unpacked it and followed the installation instruction from README file.

The error from my initial post I've got after running the fourth step.
