True, that was an excited blurb of misinformation I gave there, but rpath keeps you from having to use LD_LIBRARY_PATH which would require you to add a script to first set, then call the application, and while it is not much of a burden, it makes things a little bit easier to use. And is there a way to use libdl in a "D-ish" way? I remember the Old c++ way being a bit sloppy but not at all bad, simply requiring you to create a function that returned a class (if my memory decides to work).And the DDl project is dead for now, and shows little hope of revival. If someone could point me in the direction of a similar library I would very much appreciate it! And yes, the plugin system would be nearly impossible (if not outright) -- alexhairyman <[email protected]>
