Note in the bin directory there is the .bat file I use to set the environment up on windows
The best way of getting the rclone source is to install go, and git, set the GOPATH (see that bat file) then type
go get -u -v github.com/ncw/rclone
changing into the rclone source directory
%GOPATH%/src/github.com/ncw/rclone then running
go build or
go install will build the binary.
If you want mount too, then you’ll have to make sure you have mingw installed, the winfsp developemnt kit, and build with
go build -tags cmount.
Hope that helps!
