Hi,

By default DPDK build for the current CPU.

I guess in your virtual machine configuration you enabled emulation of a CPU instead of CPU passthrough. This is the default of libvirt I think. The default emulated CPU has no fancy insturctions by default, and is, it seems from your error log, set in 32bit mode.

Objet : [dpdk-users] DPDK build failed in virtual machine

Hi,

A naive question, but I couldn't find any clue when searching Internet.

When I build DPDK in a CentOS-6.3 virtual machine, I got some errors:

[wzh@CentOS6-compiler dpdk-stable-18.05.1]$ make config T=x86_64-native-linuxapp-gcc
Configuration done using x86_64-native-linuxapp-gcc

But build in host (CentOS-6.3) seems fine. Does it means that DPDP cannot be
build in virtual machine?

Thanks.

What do you mean "set in 32bit mode"? The arch of virtual machine is x86_64, so the cpu should
be in 64 bit mode.

Thanks.

can you try compiling dpdk after setting 'Copy host CPU configuation'
option under CPU settings of that VM in virt-manager.

?You can also double check by doing cat /proc/cpuinfo in the guest. But the message is clear, your guest CPU is x86 (32 bit).
