[anandbonde]

Context

Bing is a important collaborator for Demikernel and a path to production. Many Bing services run on Windows. So, having a fully supported Windows port is crucial.

Goal:

• [ ] Provide a seamless build mechanism for Linux and Windows (based on Makefiles)
• [ ] Build all Demikernel components (including tests and examples) on Windows
• [ ] Successfully run all tests Demikernel tests on Windows

Proposed Solution

• [ ] Support a seamless build mechanism for Linux and Windows
  • [x] Split Makefiles for Linux and Windows (https://github.com/demikernel/demikernel/pull/273)
  • [ ] Add Windows Makefiles and ensure that all components build successfully
• [ ] Implement a "Catnap"-like solution for Windows

Alternative solutions

Handle all platform specific code via PAL (Platform Abstraction Layer).
