Description Conrad Kostecki gentoo-dev

If you emerge >=dev-db/mongodb-5.0.0 on a CPU, which does not support AVX instructions, compilation will work, but mongodb won't run due invalid op code.

The ebuild shown check somehow for those instructions or at least inform the user about this.

As my CPU does not offer this, I get those messages:

[  455.495967] traps: mongod[11430] trap invalid opcode ip:603898afbdd1 sp:7ffc0e61b720 error:0 in mongod[603896397000+37c3000]

Thanks for reporting Conrad, I wasn't aware of this.

They did a similar thing with ARM64, now requiring at least ARMv8.2, instead of ARMv8.0. But it's easy to revert it, here's a patch FreeBSD uses for ARM:

You could probably replace sandybridge with generic in https://github.com/mongodb/mongo/blob/master/SConstruct#L2543
