Hi,
when I use option "./setup.sh --compile-pcap"，I can compile successfully. But use option "./setup.sh --compile-dpdk", I can't compile all examples. I'm sure mOS is compile successfully.

Hi fruitdish,

I have not really seen this error before. Can you please share with me your environment settings (OS, gcc version, etc.)? I would also suggest that you try upgrading your gcc to a newer version and verify whether you are able to compile mOS with it. Thanks.

Hi jamshed,
I build a CentOS system in virtual machine

kernel version : 3.10.0-514.26.2.el7.x86_64
gcc version : gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11)
glibc version : GNU ld version 2.25.1-22.base.el7
dpdk version : dpdk-16.11

I can capture packets through DPDK and compile mOS is successful !

So what was the problem in the first place? Also, we have not tested mOS in a virtualized environment. We first suggest you test out mOS on bare metal machines. Thanks.

Hi,
when I use option "./setup.sh --compile-pcap"，I can compile successfully. But use option "./setup.sh --compile-dpdk", I can't compile all examples. I'm sure mOS is compile successfully.
errors follows:
CC ../../core/lib/libmtcp.a
/usr/bin/ld: unrecognized option '-Wl'
/usr/bin/ld: use the --help option for usage information
collect2: error: ld returned 1 exit status
make: *** [midstat] Error 1
Thanks for your replay

@MikeCreken,

Can you please set V=1 in the midstat Makefile and recompile? I will like to see the full output of the gcc compilation/linking command.
