Re: [Libguestfs] Libguestfs with Yara rules error



I did not send you the project I did with Libguestfs... Futhermore there is a git repo here! https://gitlab.com/luisfm/fitz-roy and a post on my blog http://acmpxyz.com/fitz_roy.html. Thanks so much for that terrific library in order to access VMs!

Cheers and merry christmas!

Hi Richard.

Few days ago, I installed libyara a libguestfs properly. But when I load
a yara rule and scan it via guestfs_yara_scan, my binary throughts
following error:

libguestfs: error: deserialise_yara_detection_list: Success

And function exists with NULL value. As we can see this function is on
lib/yara.c from libguestfs git. I think that these yara functions are an
integration for yara C api. All debug and trace log is in
libguestfs-yara.debug file.
