Less v2 does not compile Twitter's Bootstrap 2.x

Question

When compiling Twitter's Bootstrap 2.3.2. with Less 2 i found to following error:

NameError: #grid > .core > .span is undefined in /home/bootstrap-2.3.2/less/navbar.less on line 199, column 3:
198 .navbar-fixed-bottom .container {
199   #grid > .core > .span(@gridColumns);
200 }

How can i fix this?

Answer 1

In the less/navbar.less file:

Replace:

.navbar-static-top .container,
.navbar-fixed-top .container,
.navbar-fixed-bottom .container {
  #grid > .core > .span(@gridColumns);
}

With:

.navbar-static-top .container,  
.navbar-fixed-top .container,
.navbar-fixed-bottom .container { 
width: (@gridColumnWidth * @gridColumns) + (@gridGutterWidth * (@gridColumns - 1));
}
