Hi Michael:

Seems the examples makefile seems to be broken, easy to reproduce on
master branch, below is the outputs on Ubuntu 14.04 amd64 version:

~/work/dpdk$ export RTE_SDK=/home/steeven/work/dpdk
~/work/dpdk$ cd /home/steeven/work/dpdk/examples/helloworld/
~/work/dpdk/examples/helloworld$ export RTE_TARGET=x86_64-native-linuxapp-gcc
~/work/dpdk/examples/helloworld$ make
/home/steeven/work/dpdk/mk/internal/rte.extvars.mk:57: *** Cannot find
.config in /home/xueming/work/dpdk.  Stop.
~/work/dpdk/examples/helloworld$ cd ../cmdline/
~/work/dpdk/examples/cmdline$ make
/home/steeven/work/dpdk/mk/internal/rte.extvars.mk:57: *** Cannot find
.config in /home/xueming/work/dpdk.  Stop.


Thanks,
Steeven

Could you show your compile error log? And how to reproduce it?

Thanks,
