(I just didn't like the link stuff and I still don't understand what ROOT is there for).<BR>
<BR>
The point was to add Unix.link where it belongs, m3core, and use it from where can't depend on new m3core.<BR>
And maybe go overboard in sharing the source, to a trivial one line function (less trivial on Win32, in order to support pre-Win2000 OS).<BR>
The point was to put the files in lib and also leave them in pkg, without wasting space.<BR>
The decision now, which I still have to try, is to stop putting the files in pkg, so then no hardlink needed.<BR>
<BR>
<BR>
$origin vs. full paths is still debatable and I still convinced $origin is the way to go.<BR>
<BR>
I'm also inclined to put $origin and $origin/../lib in rpath, so backups can flatten the structure to just one directory:<BR>
/backup/cm3<BR>
/backup/libm3core.so<BR>
/backup/libm3.so<BR>
<BR>
in some /hypothetical future/ where cm3 is dynamically linked.<BR>
As long there are no "duplicates" -- files in both bin and lib, the runpath remains fairly clear/unambiguous.<BR>
And even then, the order is pretty clearly left to right..<BR>
