They are optional, as each package must provide default values for each variant it makes available. Variants can be specified using a flexible parameter syntax ``name=<value>``. For example, -``spack install libelf debug=True`` will install libelf built with debug +``spack install mercury debug=True`` will install mercury built with debug flags. The names of particular variants available for a package depend on what was provided by the package author. ``spack info <package>`` will provide information on what build variants are available. @@ -971,11 +971,11 @@ provide information on what build variants are available. For compatibility with earlier versions, variants which happen to be boolean in nature can be specified by a syntax that represents turning options on and off. For example, in the previous spec we could have -supplied ``libelf +debug`` with the same effect of enabling the debug +supplied ``mercury +debug`` with the same effect of enabling the debug compile time option for the libelf package. Depending on the package a variant may have any default value. For -``libelf`` here, ``debug`` is ``False`` by default, and we turned it on +``mercury`` here, ``debug`` is ``False`` by default, and we turned it on with ``debug=True`` or ``+debug``. If a variant is ``True`` by default you can turn it off by either adding ``-name`` or ``~name`` to the spec. |
