# RunningOnMinGW

MLton runs on MinGW, a library for porting Unix applications to Windows. Some library functionality is missing or changed.

## Notes

- To compile MLton on MinGW:

  - The GMP library is required.

  - The Bash shell is required. If you are using a prebuilt MSYS, you probably want to symlink `bash` to `sh`.
