'minimum common factor' and cross-compile to that system and then recompile everything on it, but I solved hacking the virtual machine sources, so my guess is that you can have 'forwards compatibility' if you can get a sufficient old version of your tool chain and OS to cross-compile from newer.<br>Modula-3 had this nice thing of emitting the "assembly sources" and emit native code for the platform in-situ and relink everything (so sort of eliminate the requisite of having an older compiler,
but just native gcc nice to do). Maybe this would be a nice to have item for next releases, wouldn't be?<br>Thanks in advance<br><br> <br><br>--- El <b>lun, 14/5/12, Jay K <i><jay.krell@cornell.edu></i></b> escribió:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>De: Jay K <jay.krell@cornell.edu><br>Asunto: Re: [M3devel] libXaw.so.6 again<br>Para: "Mika Nystrom" <mika@async.caltech.edu>, dragisha@m3w.org<br>CC: "m3devel" <m3devel@elegosoft.com><br>Fecha: lunes, 14 de mayo, 2012 02:20<br><br><div id="yiv1610418929">
