Yes. I'm also trying to port this to windows. So, I have lots of changes to make the code more portable: https://codereview.qt-project.org/#/c/184401/ and the 50 changes depending on that. I will try to get those into an acceptable form and post them here.

In principle yes. However, perfparser doesn't include elfutils' test framework and writing the tests I've found some problems with the frame pointer unwinders. So don't just take that commit ... I'll send the new versions to you personally.
