Re: [toolbox-l] How to start easily ....

[Marc S. <ma...@au...>]

If your existing packages are built statically and were not loaded into
/usr or /opt/freeware, then installing things from the AIX Toolbox should
not interfere with your existing system.  The problems are with non-static
executables.

I tried to detail the problems which are caused by the differences in production
of shared objects between the Bull-provided software and the Toolbox in the
README.

I don't expect that the Bull software will interfere with the Toolbox software,
but the Toolbox software easily can interfere with the Bull software.  That's
because we are providing objects accessible in the default system
directories with different characteristics than shared objects delivered from
Bull.

The entire list of .a files which the Toolbox ships in /usr/lib 
(actually they are symlinks in /usr/lib) (based on what is installed on my
own system -which is more than in the published Toolbox) constitutes the 
majority of the potential conflicts:

   libMagick.a libXaw3d.a libXpm.a liba2ps.a libart_lgpl.a
   libbz2.a libdb.a libdeflt.a libfl.a
   libform.a libgdbm.a libgdk_pixbuf.a libghttp.a
   libgif.a libgnome.a libgnomecanvaspixbuf.a libgnomesupport.a
   libgnomeui.a libgnorba.a libgnorbagtk.a libgpc.a
   libgrove.a libgtkxmhtml.a libguile.a libhistory.a
   libintl.a libjabber.a libjpeg.a libltdl.a
   libmegawidget.a libmenu.a libname-server.a libncurses.a
   liborbit-c-backend.a libpanel.a libpng.a libpth.a
   libreadline.a libscg.a libschily.a libslang.a
   libsp.a libspgrove.a libstyle.a libtiff.a
   libttf.a libungif.a libxml.a libxode.a
   libz.a libzvt.a

If you have any of these installed in /usr/local/lib from Bull, and if the
executables which linked against those libraries contains a built-in
LIBPATH which has /usr/lib ahead of /usr/local/lib, then you will need to
do something to avoid problems (those mitigating measures are detailed in 
the README).  It basically involves using LIBPATH to dictate where your
shared objects get loaded from, which works except for programs which are
setuid/setgid.  If you have no programs which are setuid/setgid which
have conflicts, then you're set to go.

We are working with the libtool maintainers on a system whereby the shared
library production on AIX4 and AIX5 will be as consistent as possible with
the rest of the UNIX community.  When we have everything in place, we will
be rebuilding the modules with the new algorithm, which would likely be in
place in libtool 1.5.  Once that is done, tools which are built using the
latest version of libtool will produce shared objects which work on AIX4 and
AIX5 (both Power and IA) without user-intervention.  That will benefit 
everybody building a tool which uses libtool (which is quite a lot).
Unfortunately, this will introduce a round of binary incompatibilities
which will cause us and our existing users pain in the short run.  We'll
be explaining the upgrade procedures once we're ready to roll out.
