Hi,

i’ve successfully compiled everything on a Windows Subsystem for Linux (Ubuntu 16.04). When i’m launching grin, I can see the UI and everything. However, “Current Status” is stuck to “Initializing”.  
(I don’t know if it’s useful but I can find peers)

Thanks for trying this out. Others have tried this before and the main culprit was storage. Grin relies on Memory Maps (mmap) both directly and indirectly through LMDB, and it appears that WSL’s support for mmap is rather broken. That being said the WSL team is aware of it:

So I’d suggest upvoting the issue and hope it eventually gets tackled.
