Yocto runs only one task inside at a time

Question

I have setup my development environment inside Virtual Machine running Ubuntu 14.04. My company doesn't allow me to run direct Linux Flavoured OS may be due to security reasons.

One thing I have observed is that in VM it only runs one task ast a time whereas if i run on my personal laptop it runs multiple tasks at a time.

Is there any way to configure poky in local.conf file for example or any other file for it to run multiple tasks at the same time. I have given more than 6 GB of RAM to the VM.

As it is running one task, build is taking a lot of time..

Thanks for your time

Answer 1

bitbake task executor enquires for number of CPUs dynamically, so it seems that you might have allocated 1 cpu to your VM. You might be able to see CPUs with below command in VM

lscpu

You might want to allocate more CPUs. VirtualBox lets you do that

1. Stop virtual machine
2. Click settings-> click system -> click processor -> Change the number of procesors.
