We both work for infrastructure teams who are supporting a project team
that is developing a DPDK application that runs across multiple CPU
architectures and encountered the error.
The error comes from g++ (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0:
[CXX] g++ -o utils/pcap_handle.o -c utils/pcap_handle.cc -g3

make[1]: *** [drivers/pmd.o] Error 1
Do you believe that more permissive compiler flags are the better answer?
