[dpdk-dev] Compiling DPDK is not working on Red Hat 6.7

[Raslan Darawsheh]

Hi,

When trying to compile DPDK on Red Hat Enterprise Linux Server release 6.7 (Santiago) it fails to compile.

This is the compilation error that is being seen:
LD test

Hi,
checking "man clock_gettime" I see: "Link with -lrt (only for glibc
versions before 2.17)."

RH 6.7 is at glibc 2.12, I haven't check the build, but you might easily
run the make with V=1 and see the call.
Check if it contains -lrt for the linking step.

I suspect we need -lrt after -lrte_eal.

Please could you try the following patch?

Do you know where the flag -lrt is set?
Is it in your environment LDFLAGS? (it is my guess for the fix).
