Hi, saranshkataria

You can connect to Libra Core from Windows using WSL. Use the following article to get started with it on a Windows System.

Couple of notes regarding getting this to build on Windows (at least my progress so far).

First, you'll need to install all of the dependencies in scripts/dev_setup.sh yourself and add them to PATH. These are Rust (obviously), CMake, Go, and protobuf. For protobuf, both the bin and the include directory will need to be in PATH.

As for getting it to build (in whatever way possible), my progress so far:

1. libra_node depends on signal-hook which does not work on Windows at all.

Remove signal_hook dependency and comment out use of signal_hook and definiton/call to register_signals in https://github.com/libra/libra/blob/master/libra_node/src/main.rs

2. clap has a default feature that is not supported on Windows.

Change all clap = 2.32.0 dependencies to clap = { version = "2.32.0", default-features = false }

3. jemallocator doesn't build on x86_64-pc-windows-msvc.

Comment out dump_jemalloc_heap_profile function in node_debug_service.rs, and the associated call and import in debug_interface/src/lib.rs

Currently, I'm wrestling with rocksdb. Release 0.12.2 builds correctly on Windows, but the Rust interface has changed. Libra is pinned to a specific commit (4f8c6b3a48c7acb0c81f9bb91e7d8493b1c5a73e), which errors with Cannot open include file: 'snappy.h'. This should be solvable, though. I'll update once I have it figured out.

The dependencies needed to build Libra have been simplified so this should make it easier to build on windows (I believe building rocksdb maybe be the only hurdle now), though it sounds like using WSL is also an option.
