<BR><SPAN>>> But why would you compile a new cm3 with an old m3core?</SPAN><BR><SPAN></SPAN> <BR><SPAN>That is what the "release" builds do on the Tinderbox.</SPAN><BR><SPAN> If you can fix that, please do. :)<BR>Notice how I broke them the other day?<BR>But not the "last ok" build?</SPAN><BR><SPAN><BR>They start with a 5.4 compiler.<BR> They do NOT build m3core, libm3.<BR> Not sure about m3cc.<BR> They start with sysutils, then, in whatever order,<BR> m3quake, m3middle, m3front, m3back, cm3.<BR> Then they use that new cm3 to build<BR> m3cc if not done already <BR> (clean)<BR> m3core, libm3, sysutils, m3front/quake/back/middle, cm3.<BR><BR>At some point, you know, cm3 could not build m3core, when<BR>cm3 didn't know about LONGINT and m3core used it.<BR>I don't know if 5.4 is such a version.<BR></SPAN> <BR><SPAN></SPAN> <BR><SPAN> > I thought the use of -rpath overcomes the need for LD_LIBRARY_PATH?</SPAN><BR><SPAN></SPAN> <BR><SPAN>That's not the entire story.</SPAN><BR><SPAN>If you use -rpath and point to /usr/local/cm3/pkg/foo/linux, then</SPAN><BR><SPAN> - you end up with a huge presumably inefficient runpath</SPAN><BR><SPAN> This can be addressed by using /usr/local/cm3/lib instead.</SPAN><BR><SPAN></SPAN> <BR><SPAN> - you end up with insecure /tmp for distribution builds</SPAN><BR><SPAN> This can be addressed by using $origin or changing how distribution builds are done.</SPAN><BR><SPAN></SPAN> <BR> - You can't "easily" move the install. Though there are utilities in various OSes to edit the paths later, or you can relink upon install. I didn't make that strategy up.<BR><BR><SPAN> > Is LD_LIBRARY_PATH so bad if you insist on moving the libraries someplace other than the rpath used in their linkage?</SPAN><BR><SPAN></SPAN>
<BLOCKQUOTE><SPAN></SPAN> <BR><SPAN>I don't understand. Right, if you want to move stuff around, LD_LIBRARY_PATH is one solution. $origin is another. They aren't equivalent and they have various pluses/minus. Searching the web definitely leads me to favor $origin.</SPAN><BR><SPAN>"The Sun linker developer say so." Plus, LD_LIBRARY_PATH is not scoped to a particular executable, unless you use wrapper scripts. /etc/ld.so.conf or such on birch including /usr/local/cm3/lib broke my own use of my $HOME/cm3/bin, because those binaries are supposed to use $HOME/cm3/lib, but there is (often) just one LD_LIBRARY_PATH, again, unless you write wrapper scripts.</SPAN><BR><SPAN></SPAN> <BR>
<DIV>If we force everyone to install to /usr/local/cm3 or /opt/cm3, the issue is reduced, granted<BR></DIV>
