undefined reference in vagrant

[aghamir]

Hi @Wenzel ,
I've ran main.py in vagrant. I've got this error:

vagrant@jessie:/vagrant/nitro$ ./main.py nitro_win7x64

Also when I run process_list in libvmi, I get this error:

Hi,

how did you run vagrant ?
Did you use the packaged option, or did you use the defaults (NFS, full build) ?

[Wenzel]

Also, i have doing some changes to the playbooks recently.
Did you pulled from master on kvm-vmi ?
you should be at this commit : fix libvmi in provision_packaged

[aghamir]

With NFS and full build(Not packaged).

[Wenzel]

Ok, last time i checked, it was working.
But i will rebuild everything tonight and see if i can reproduce your error.

Otherwise, checkout the latest master, and if you just want to work on Nitro python library, i advise you to use the packaged option. It's much faster.

[aghamir]

Yes, I am at latest commit. Tnx, I will try it with packaged option.

hi @aghamir

sorry but i cannot reproduce your bug.
All i could find was that the QEMU binary was being replaced by the Debian one, so i moved the QEMU installation a bit later.
Did you tried the packaged playbook ?

[aghamir]

Package playbook was OK. Maybe QEMU was the point. Thank you a lot. We can close this.
