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)
