Is anyone successfully using DPDK with UHD 3.15.LTS?
The RHEL 7 repositories install DPDK 18.11, which UHD won't build with (UHD
3.15.LTS requires 17.11 exactly; UHD master works with DPDK 18.11 but I want to
use a LTS version). So I uninstalled the 18.11 DPDK packages and built 17.11 by
hand; everything installed fine and seems to work on the DPDK end.
However, building UHD 3.15.LTS fails with many errors like those below. I'm
using:
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28)
Any ideas? I might try installing and trying to build with a newer version of
the compiler and see if that makes a difference.
