BUILD_NATIVE Vs Xeon E5 V2 Vs Xeon E5 V3
hi,
i builded Asterisk 16.18 with BUILD_NATIVE on Xeon E5 v3 (Intel(R)
Xeon(R) CPU E5-2670 v3 @ 2.30GHz)
on machine when i want run Asterisk it hangs with Illegal instruction see below (Intel(R) Xeon(R) CPU E5-2660 v2 @ 2.20GHz)
is it only way to disable BUILD_NATIVE ?
or can be somehow specified to build for “something like xeon E5”?

Uh i forgot. the build machine is a VMware VM and asterisk build is inside a docker container (CentOS7) as RPM

update
my cpu family (hundred of VMs) is based on this (-march)
corei7-avx core-avx2
corei7
note:
you can check your march code like this
gcc -c -Q -march=native –help=target |grep arch
so it looks like i will stay with corei7 (anybody knows if avx is “big”
performance save impact?)
i’ll change build process to
menuselect/menuselect –disable BUILD_NATIVE menuselect.makeopts
then i need “force” CFLAGS=”-march=corei7″ in rpm build . any hints ?
WARNING:
there are changes in -march names through gcc versions
