Hi DPDK devs, I'm hitting a build failure with dpdk 20.02.1 with rte_ethdev.h that's happening seemingly at random: make install T=arm64-armv8a-linuxapp-gcc -j In file included from /tmp/openvpp-testing/dpdk/lib/librte_ethdev/rte_class_eth.c:13:0: /tmp/openvpp-testing/dpdk/lib/librte_ethdev/rte_ethdev.h:4287:10: fatal error: rte_ethdev_core.h: No such file or directory #include <rte_ethdev_core.h> ^~~~~~~~~~~~~~~~~~~ compilation terminated. make[5]: *** [rte_class_eth.o] Error 1 make[5]: *** Waiting for unfinished jobs.... make[4]: *** [librte_ethdev] Error 2 make[3]: *** [lib] Error 2 make[2]: *** [all] Error 2 make[1]: *** [pre_install] Error 2 make: *** [install] Error 2
Full log here: https://logs.fd.io/production/vex-yul-rot-jenkins-1/csit-dpdk-perf-verify-master-3n-tsh/11/archives/log.html.gz This doesn't happen every time. It took me five builds on two machines (for a total of 10 builds) to hit this issue, but it did eventually happen. I tried this with 20.02 at first and it seemed to be happening more frequently, but I don't have enough data to really tell if there's an actual difference in frequency. We're not doing anything special, just downloading and extracting the archive, then setting CONFIG_RTE_LIBRTE_MLX5_PMD and CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC to y in config/common_base and then running make install T=arm64-armv8a-linuxapp-gcc -j. As mentioned in the subject, the build server is a Taishan ARM server. Any ideas on how to fix (or workaround) this? Is there a chance meson build would fix this? If so, how do we make sure we build testpmd with mxl5 support and how do we set CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC with meson build? Thanks, Juraj
