Hi 

 

I use dpdk in my product. I can't change my dpdk version.

I compile it on a server that have avx.

Most of the time, it run on machine that have avx, but not always.

 

When running the product on a machine with no avx, it crash on illegal
instruction.

The current solution is to build it on a computer with no avx.

 

Is there a compilation flag to disable avx? So it doesn't matter on
which computer I compiled it.

 

Compile flag

defconfig_x86_64-default-linuxapp-gcc

 

Dpdk version

PACKAGE_VERSION_MAJOR_NUMBER=1

PACKAGE_VERSION_MINOR_NUMBER=6

PACKAGE_VERSION_PATCH_NUMBER=0

PACKAGE_VERSION_BUILD_NUMBER=18

 

Gcc version

gcc (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4)

 

OS

CentOS release 6.3 (Final)
