Hello Oki-san,
The trick to fix it was this, I finally found it in the example Makefiles with
V=1 flag.
-Wl,--whole-archive -Wl,--start-group -lintel_dpdk -Wl,--end-group -Wl,--no-whole-archive
Thank you for the advice you provided, I couldn't have fixed it without your
suggestions... it got me to look more closely at the linking. Importantly,
"-Wl,--whole-archive" includes the entire archive whether or not it's called
from other objects, so we don't lose the constructors, just like you said.
Matthew.
