[dpdk-dev] SSSE3 instruction set not enabled ERROR - use msse4.2

[dpdk-dev] SSSE3 instruction set not enabled ERROR - use msse4.2

[Raj Ravi]

Hi,
I was facing this error:
"SSSE3 instruction set not enabled" while building dpdk.

Using the following commands:
make config  T=x86_64-native-linuxapp-gcc
make install  T=x86_64-native-linuxapp-gcc

So, again I tried like this :
make config    T=x86_64-native-linuxapp-gcc   EXTRA_CFLAGS="-msse4.2"
make install    T=x86_64-native-linuxapp-gcc   EXTRA_CFLAGS="-msse4.2"

Now, the build goes through.
Is This method correct  to follow ?

Thanks

It should not happen with last version (1.7.1).

Please precise which DPDK version was it and what is your CPU
(/proc/cpuinfo could help).

Thanks

Hi,
What is your build environment (processor)?
I got same error with AMD Phoenom II, doesn't have SSSE3 instruction.

I have built dpdk-1.7.0 and faced this error.
I have tried building dpdk-1.7.1 , but faced the same error.


Only after adding msse4.2, this errors goes away.


Thanks

As Thomas said, it won't happen with 1.7.1, but the real question is, what do
you want to run this on. enabling sse4.2 in the compiler makes the error go
away, but it will cause run time failure if you try to run the built binary on a
system that doesn't support sse4.2.
