When running lessc use the --relative-urls flag.

lessc --relative-urls

It's poorly documented, but by default it is false which means that all @imported files will maintain their urls (e.g. background-image, font-face, etc) as they are. This is because less was already doing this and many users expect it to leave their urls alone.

When the relative-urls flag is used, lessc rewrites all of the urls according to the location of the less/css file being imported.

Example

/dir1/style/main.less

// if you don't include (less) lessc will leave bootstrap
//   as an @import at the top of the lessified css file
@import (less) '../bootstrap/bootstrap.min.css';

/dir1/lib/bootstrap/bootstrap.min.css

background-image:url("../img/bs-img.gif");

Result:

/dir1/style/main.css

background-image:url("../bootstrap/img/bs-img.gif");
