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.

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
