Adding -DNDEBUG flag will cause the helloworld example to crash #705

Closed renzibei closed 1 year ago

renzibei commented 2 years ago

Hello, I find that if -DNDEBUG flag is added to the compile-options, the helloworld example will crash. After the modification, the CFLAGS line in the Makefile file becomes 

CFLAGS += -O -DNDEBUG -gdwarf-2 $(shell $(PKGCONF) --cflags libdpdk)

And when I running the helloworld program, it will crashes or print many lines of unknown event: 00000000.

Can you help look into the reason of it?

I used the compiled static library of f-stack. Maybe the status of NDEBUG macro in the header files of f-stack codes will affect the ABI stability?

Fixed.
Because assert((kq = ff_kqueue()) > 0); was be ignored and nevents used usigned type.
