...dpdk/lib/librte_eal/common/arch/x86/rte_cycles.c:67:2: error:
nested extern declaration of ‘pread’
from pread man page:
pread(), pwrite():
_XOPEN_SOURCE >= 500
|| /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
For glibc < 2.12 _XOPEN_SOURCE >= 500 is required.
Adding _GNU_SOURCE define to the file which implies _XOPEN_SOURCE=700
