[dpdk-users] Gcc 6.4 failure compile

[dpdk-users] Gcc 6.4 failure compile

[Harouat, Karim (Nokia - FR/Lannion)]

Hello

I'm trying to compile DPKD 17.08 (hash 02657b)

I have the following error



dpdk/build/lib/librte_acl/acl_run_sse.h: In function 'resolve_priority_sse':
/builds/x86_64-pc-linux-gnu/dpdk/srcdir/lib/gcc/x86_64-pc-linux-gnu/6.4.1/include/smmintrin.h:179:1: error: inlining failed in call to always_inline '_mm_blendv_epi8': target specific option mismatch
_mm_blendv_epi8 (__m128i __X, __m128i __Y, __m128i __M)
^~~~~~~~~~~~~~~

Any idea please ?

Karim H.

Hi
What machine are you using? And what target are you using?
I met this problem before. 
That time, I used cross-compiling for atom, and gcc thinks atom don't support SSE4, but the instructions in your error are SSE4. So there are compilation errors.

Hi

I try to build the target x86_64-native-linuxapp-gcc on a x86_64 machine with linux.

Re: [dpdk-users] Gcc 6.4 failure compile

[Li, Xiaoyun]

Can you show the results of Flags of your machine? Use "lscpu" or "cat /proc/cpuinfo".
Are there sse4_1 and sse4_2?

Aw you got it sse4_1 sse4_2

It is not for the machine on which  I'm working the binary, how can I make the gcc  to ignore the host cpu flags ?

Re: [dpdk-users] Gcc 6.4 failure compile

[Li, Xiaoyun]

Em.. Not really.
I thought your machine doesn't support sse4. In that way the sse4 instructions cannot be recognized by gcc and would appear compilation errors.

But it seems that your machine supports sse4.
You can try " gcc -march=native -dM -E - </dev/null | grep SSE4_2".
If there is output " #define __SSE4_2__ 1", gcc thinks native machine supports sse4.2. Then I am not sure why there is error.
If not, gcc thinks native machine doesn't support sse4. Then there should be errors.

Anyway, maybe you can try cross-compilation? Such as T= x86_64-hsw-linuxapp-gcc? But remember adds a config file "defconfig_x86_64-xxx-linuxapp-gcc" in config.

Re: [dpdk-users] Gcc 6.4 failure compile

[Harouat, Karim (Nokia - FR/Lannion)]

Thanks a lot for your answer!

My machine supports it properly :-(

gcc -march=native -dM -E - </dev/null | grep SSE4_2
#define __SSE4_2__ 1

That's I'm trying to do a cross compilation. I created a new file defconfig_x86_64-mine, which included '#include "defconfig_x86_64-native-linuxapp-gcc"'
The CONFIG_RTE_MACHINE=core2

Re: [dpdk-users] Gcc 6.4 failure compile

[Harouat, Karim (Nokia - FR/Lannion)]

Hi
I fixed my issue by changing the CONFIG_RTE_MACHINE value
Core 2 was not proper to my case.
