Hi,
It compiles ok for me with the latest HEAD and clang 3.70:
$ make install -j T=x86_64-native-linuxapp-clang CC=/usr/bin/clang
...
Build complete [x86_64-native-linuxapp-clang]
...
$ clang --version
clang version 3.7.0 (tags/RELEASE_370/final)
Target: x86_64-redhat-linux-gnu
Thread model: posix
I do have to avoid using the ccached clang since it gives a (different) error about macro expansions. However, that isn't the issue you are seeing.

Can reproduce this here, Ubuntu clang version 3.6.2-1 (tags/RELEASE_362/final) (based on LLVM 3.6.2)
This issue seems to be caused by a lack of intrinsic CFLAGS, clang and GCC build output with make V=1 on the same machine (unnecessary output stripped):
clang -Wp,-MD,./.eal_pci.o.d.tmp -m64 -pthread -march=native -DRTE_MACHINE_CPUFLAG_SSE -DRTE_MACHINE_CPUFLAG_SSE2 -DRTE_COMPILE_TIME_CPUFLAGS=RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2
gcc -Wp,-MD,./.eal_pci.o.d.tmp -m64 -pthread -fPIC -march=native -DRTE_MACHINE_CPUFLAG_SSE -DRTE_MACHINE_CPUFLAG_SSE2 -DRTE_MACHINE_CPUFLAG_SSE3 -DRTE_MACHINE_CPUFLAG_SSSE3 -DRTE_MACHINE_CPUFLAG_SSE4_1 -DRTE_MACHINE_CPUFLAG_SSE4_2 -DRTE_MACHINE_CPUFLAG_AES -DRTE_MACHINE_CPUFLAG_PCLMULQDQ -DRTE_MACHINE_CPUFLAG_AVX -DRTE_MACHINE_CPUFLAG_RDRAND -DRTE_MACHINE_CPUFLAG_FSGSBASE -DRTE_MACHINE_CPUFLAG_F16C -DRTE_MACHINE_CPUFLAG_AVX2 -DRTE_COMPILE_TIME_CPUFLAGS=RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2,RTE_CPUFLAG_SSE3,RTE_CPUFLAG_SSSE3,RTE_CPUFLAG_SSE4_1,RTE_CPUFLAG_SSE4_2,RTE_CPUFLAG_AES,RTE_CPUFLAG_PCLMULQDQ,RTE_CPUFLAG_AVX,RTE_CPUFLAG_RDRAND,RTE_CPUFLAG_FSGSBASE,RTE_CPUFLAG_F16C,RTE_CPUFLAG_AVX2
There is no copy-paste error above: the clang intrinsic CFLAGS is much shorter than GCC.
Strangely, this issue also exists when building i686 gcc target *on a 32bit host/VM*. Git bisect shows that this issue exists on 32bit target / 32bit host since commit 9144d6b, which optimized eal/x86 rte_memcpy.
It looks like the build-system is not correctly identifying the intrinsics to build with. I've had a look through mk/toolchain/clang/* and mk/rte.cpuflags.mk but haven't seen anything I think could be the cause...
Perhaps somebody with familiarity with the build system could take a look?

I had all kinds of very weird failures using the 64 bit clang target related to missing CPUFLAGS. For a while I hacked around it by adding a whole ton of -D for missing RTE CPUFLAGS macros. But then some further DPDK changes came and caused clang bud failures I could not debug and I had to give up and switch back to GCC. While I can't confirm this exact error I can 100% confirm very similar errors using Ubuntu 15.10 and the included clang with it.
I think the general problem is that there isn't much in the way of regression testing for the build on this compile target. So unless it breaks for just the right expert at the right time nobody finds it and tracks it down.
Matthew.

P.S.
I see that similar, but not quite the same errors, if I use the -gcc target with clang:
$ make install -j T=x86_64-native-linuxapp-gcc CC=/usr/bin/clang

We suspect this might be an architecture dependent issue.
Could you tell us which CPU you are using?

From what I have seen, this issue happens on Broadwell/Haswell with clang versions < 3.7.
This what I see when using clang 3.6.2:
clang -Wp,-MD,./.eal.o.d.tmp -m64 -pthread -march=native -DRTE_MACHINE_CPUFLAG_SSE
-DRTE_MACHINE_CPUFLAG_SSE2 -DRTE_COMPILE_TIME_CPUFLAGS=RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2
This is what I see with clang 3.7:
clang-3.7 -Wp,-MD,./.eal.o.d.tmp -m64 -pthread -march=native -DRTE_MACHINE_CPUFLAG_SSE
-DRTE_MACHINE_CPUFLAG_SSE2 -DRTE_MACHINE_CPUFLAG_SSE3 -DRTE_MACHINE_CPUFLAG_SSSE3
-DRTE_MACHINE_CPUFLAG_SSE4_1 -DRTE_MACHINE_CPUFLAG_SSE4_2 -DRTE_MACHINE_CPUFLAG_AES
-DRTE_MACHINE_CPUFLAG_PCLMULQDQ -DRTE_MACHINE_CPUFLAG_AVX -DRTE_MACHINE_CPUFLAG_RDRAND
-DRTE_COMPILE_TIME_CPUFLAGS=RTE_CPUFLAG_SSE,RTE_CPUFLAG_SSE2,RTE_CPUFLAG_SSE3,
RTE_CPUFLAG_SSSE3,RTE_CPUFLAG_SSE4_1,RTE_CPUFLAG_SSE4_2,RTE_CPUFLAG_AES,
RTE_CPUFLAG_PCLMULQDQ,RTE_CPUFLAG_AVX,RTE_CPUFLAG_RDRAND
It looks like old versions of clang are not able to identify correctly the newer CPUs:
LLVM (http://llvm.org/):
LLVM version 3.6.2
Optimized build.
Built Aug 18 2015 (08:39:18).
Default target: x86_64-pc-linux-gnu
Host CPU: x86-64
LLVM (http://llvm.org/):
LLVM version 3.7.0
Optimized build.
Built Jan 22 2016 (17:39:46).
Default target: x86_64-redhat-linux-gnu
Host CPU: broadwell
I will submit a patch adding a note in known issues section, unless anybody knows
how to fix this in our side (as far as I know, it is a clang issue).
Thanks,
Pablo

Hello Pablo,
