Hi all, I'm now working for IOHK on the Cardano project. The Cardano code base is large and we are hitting the dreaded windows path length bug. We have already shortned build paths as much as possible but are still hitting this We're currently using ghc-8.0.2 but even ghc-8.2.2 has this issue. A snippet of the logs in included below. I took the liberty of including Tamar on this since he is the known Windows expert. Not having a local Window makes this really difficult to debug. Anyone have any solutions for this? I'm willing to backport patches if needed. I've managed to find a VirtualBox evaluation image on the Microsoft site. Hopefully that will give me enough to debug this issue.
