Hello Ferruh,

 The dpdk.spec file already tries to compile it by using
"RTE_TARGET=x86_64-default-linuxapp-gcc", look:

---
# rpmbuild --ba /root/rpmbuild/SPECS/dpdk.spec
.........
+ unset DISPLAY
+ make O=x86_64-default-linuxapp-gcc T=x86_64-native-linuxapp-gcc config
Configuration done
.........
---

 Am I right?

 But it fails... I'll need to stick with DPDK-1.8 for CentOS 6 for now,
since I can compile it without problems...

 Thanks anyway man!

Best,
Thiago
