This file documents what you need to do to get Mercury to work on an
|
|
RS/6000 running AIX using GNU C.
|
|
|
|
Previous versions of Mercury have worked successfully on AIX,
|
|
but Rodney Brown <rodneybrown@pmsc.com> reported some problems
|
|
with a recent version. We believe that we have fixed these problems,
|
|
but we do not have a machine running AIX to test it on, so we do
|
|
not know if the current version will build correctly out-of-the-box.
|
|
|
|
If there are any problems remaining, we would be happy to assist
|
|
in resolving them.
|
|
|
|
-----------------------------------------------------------------------------
|
|
|
|
1. Put the following line in the file Mmake.params:
|
|
|
|
EXTRA_CFLAGS=-mminimal-toc
|
|
|
|
This works around a fixed limit on the size of the TOC (Table of Contents)
|
|
in the RS/6000 object file format.
|
|
|
|
2. Also add the following line to Mmake.params:
|
|
|
|
RM_C=:
|
|
|
|
This prevents the intermediate C files from being removed,
|
|
which will make it easier to debug things later.
|
|
|
|
3. Follow the instructions in the INSTALL file.
|
|
|
|
The last version of Mercury which was known to work on AIX was
|
|
Mercury 0.6 -- actually a version just prior to 0.6, namely
|
|
the 30Apr1996 development snapshot (the source for this version
|
|
and a binary distribution of this version for AIX are still
|
|
available from <ftp://turiel.cs.mu.oz.au/pub/mercury/old-releases>).
|
|
That version was verified to work on AIX 4.1.3 using GNU C 2.7.2.
|
|
For that version, following the steps above would result in
|
|
an error message from the assembler, so the following additional
|
|
step was needed.
|
|
|
|
4. Change directory to the `compiler' directory, and run the command
|
|
|
|
sh ../scripts/rs6000_hack
|
|
|
|
Then continue following the instructions in the INSTALL file.
|
|
|
|
This works around a fixed limit of 32k on the size of relative jumps
|
|
in the RS/6000 object file format.
|
|
|
|
It is possible that something similar to this will still be needed,
|
|
but the rs6000_hack script no longer works as is, so a little more
|
|
hacking will be needed if that is the case.
|
|
(We'd be happy to offer assistance with this task. Indeed, we'd do it
|
|
ourselves, but we don't have an AIX machine -- donations happily accepted ;-)
