A Tactical Retreat
Posted on
If a “retreat” is the antonym of “advance”, then we’ve just made one by removing all the contents of the wxAdvanced library, affectionately known as “adv”. This library used to contain a hodge-podge of classes having nothing much to do with each other except not naturally belonging to any other library and being considered too “advanced”, in some vague sense of the word, to be in wxCore. Just the trouble of explaining what it was shows why it was a bad idea to have it in the first place and we have decided to not perpetuate this mistake any more by moving all of its contents to wxCore itself.
This change is perfectly backwards compatible for now, and will remain so in
wxWidgets 3.2, as we still provide an empty “adv” library for compatibility,
so that the existing projects linking with it continue to work. You just don’t
need to do it any longer, i.e. you can simply remove all references to this
library now. E.g. if you’re currently using wx-config --libs std,adv,html
when linking your program under Unix, just use wx-config --libs std,html
instead.
The empty compatibility husk of wxAdvanced will only be removed in some distant future, so there is no real urgency with upgrading your make- and project files, but at the very least remember that you don’t need to link with it any more when creating new projects.
