Can't compile with PF_RING support

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install PF_RING using this manual on Debian 7 Wheezy: 
http://www.stableit.ru/2014/06/pfring-debian-7-wheezy.html
2. cp /opt/pf_ring/include/pfring.h /usr/include/; cp /opt/pf_ring/lib/* 
/usr/lib/
3. go get "code.google.com/p/gopacket/pfring" 

What is the expected output?
Compiled tool

What do you see instead?
 go get "code.google.com/p/gopacket/pfring"
# code.google.com/p/gopacket/pfring
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `numa_node_of_cpu'
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `clock_gettime'
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `numa_bind'
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `numa_parse_nodestring'
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `numa_available'

After this I added numa to linker config in 
/usr/share/go/src/pkg/code.google.com/p/gopacket/pfring/pfring.go and got new 
error:
go get "code.google.com/p/gopacket/pfring" 
/# code.google.com/p/gopacket/pfring
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libpfring.so: undefined 
reference to `clock_gettime'
collect2: error: ld returned 1 exit status

For solve this I added 'rt' to linker config and tool builded successfully.

All compiles correctly with this flags:
#cgo LDFLAGS: -lpfring -lpcap -lnuma -lrt

Please fix it! 

What version of the product are you using? On what operating system?
go version go1.0.2

And you can remove pcap because it optional for PF_RING in native mode.

Are you able to compile a C/C++ binary that uses PF_RING with your current 
setup?

These errors look like they may be related to a broken install of pfring, just 
want to make sure we check that out.

Hello!

I created simple  programm for checking PF_RING compilation: 
https://gist.github.com/pavel-odintsov/62f372c882c83d85ed17

And tried to compile it with same results:
gcc test_pf_ring.c  -lpfring -lpcap
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `clock_gettime'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `numa_parse_nodestring'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `numa_node_of_cpu'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `numa_available'
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `numa_bind'

Problem was fixed in same way (I added -lnuma -lrt):
gcc test_pf_ring.c -lpfring -lpcap -lnuma
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../lib64/libpfring.so: 
undefined reference to `clock_gettime'

All compiles fine with this code: gcc test_pf_ring.c -lpfring -lpcap -lnuma -lrt

I suppose this issue related with my pf_ring compilation flags, I used non 
standard option --disable-bpf for disabling linking to pcap because it's 
obsolete. Without this flag all works pretty well but only on modern pcap 
library version. 

I think you can close this issue because my compilation flags is non standard.

Thanks for the heads-up!

I'll add a comment in pfring.go so others with the same issues can find out 
what's going on.  Just to be clear, the addition of -lnuma and -lrt are 
necessary if using --disable-bpf with pfring?
