Hi，all， I figured out why the igb_uio.ko file would not be generated, so I needed to modify the config file: CONFIG_RTE_EAL_IGB_UIO=y. However, I encountered a new "error", but the compilation did not terminate. I looked at the compilation process and couldn't explain why the information was printed.
