Hi, I'm able to send and receive packet when I compile with gcc version (Ubuntu 8.4.0-1ubuntu1~18.04) , GLIBC 2.27 and kernel 5.4.0-66-lowlatency. but when I compile with gcc gcc (GCC) 5.4.0, GLIBC 2.17 , and kernel 3.10.0-rt56 it fails at memif_buffer_alloc. Any idea why this behaviour can be .
Thanks for all the suggestions and insights.
