And the windows build error should be already fixed by a patch that squashed in next-net (https://patches.dpdk.org/patch/86804/). And for the mingw, I have same result with Ali, I can reproduce with (Fedora MinGW 9.2.1-6.fc32). But different from the CI, I am getting the error [1] for all following files: rte_random.c i40e_rxtx_vec_sse.c i40e_rxtx_vec_avx512.c i40e_rxtx_vec_avx2.c rte_ethdev.c [1] Error: invalid register for .seh_savexmm There is a stackoverflow entry for it: https://stackoverflow.com/questions/43152633/invalid-register-for-seh-savexmm-in-cygwin If I use '-fno-asynchronous-unwind-tables' as suggested there, the build works fine. So the problem may not be just 'i40e_rxtx_vec_avx512.c'. If I change the machine type from 'native' to 'corei7' [2], the build error reduced to only 'i40e_rxtx_vec_avx512.c', so the problem seems happens when avx512 is supported by CPU, in this case compiler seems has a defect. And since for 'i40e_rxtx_vec_avx512.c' the '-march=skylake-avx512' explicitly set can cause the problem seen in all machines.
