Hi Chao,
I just tried building dpdk master with these patches in ubuntu 16.04 le
guest
and I could able to.
test at ubuntu:~/DPDK$ make install T=ppc_64-power8-linuxapp-gcc -j16
....
.....
INSTALL-MAP test.map
INSTALL-APP test
Build complete [ppc_64-power8-linuxapp-gcc]
Installation cannot run with T defined and DESTDIR undefined
test at ubuntu:~/DPDK$ uname -a
Linux ubuntu 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:30:22 UTC
2016 ppc64le ppc64le ppc64le GNU/Linux
test at ubuntu:~/DPDK$ gcc --version
gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.1) 5.4.0 20160609
May be you need to check gcc again.
Thanks,
Gowrishankar
