netmap pkt_gen can't compile successfully

[dongshan]

Hi,

 

I have some problems in running netmap pkt_gen, the receiving mode seems
okay, but the sending  mode will cause segmentation fault. 

when i compile pkt_gen.c, it warns three times, in Makefile with CFLAGS
-Werror, so the warning is treated as error, so i deleted -Werror, then it
can make pkt_gen binary file, but int can't run successfully.

 

I did it on x86 64 bit Linux

Did it happen to you?
