On AIX 4.3.2 PostgreSQL compiled with the native IBM compiler xlc
(vac.C 5.0.1) passes all regression tests.  Other versions of OS and
compiler should also work. If you don't have a powerpc or use gcc you
might see rounding differences in the geometry regression test.

Use the following configure flags in addition to your own
if you have readline or libz there:
--with-includes=/usr/local/include --with-libraries=/usr/local/lib

There will probably be warnings about 0.0/0.0 division and duplicate
symbols which you can safely ignore.

Compiling PostgreSQL with gcc (2.95.3) on AIX also works.

You need libm.a that is in the fileset bos.adt.libm.  (Try the
following command.)
$ lslpp -l bos.adt.libm

Update from Andreas Zeugswetter <andreas.zeugswetter@telecom.at> for v6.5.2 info. 1999-09-14 19:34:49 +04:00
Please apply this patch to current, to fix a problem with runcheck, that installs into a different path than is configured. With this applied both postmaster and the shared libs are location independent for AIX 4.2 and up. Thanks Andreas 2000-11-09 07:17:53 +03:00			`Use the following configure flags in addition to your own`

The following patch updates the FAQ_AIX and makes C++ code work with more recent versions of the IBM C++ compiler (now called VisualAge C++). The C++ part was previously broken (g++ and xlC), thus this is zero risk. Only AIX specific parts are touched (1 Makefile.shlib line (link with $(COMPILER ) instead of $(CC) and one shell script line (parameter -C to nm to not demangle C++ symbo ls for .exp file)). I thus ask you to please apply this patch before release. With or without this patch RC1 on AIX 4.3.2 RS6000 passes "gmake check" for both the native compiler vac.C 5.0.1 and gcc 2.95.2 :-) Andreas 2001-03-27 18:56:20 +04:00

They're also linked into the > postmaster. I don't see anything unusual. Attached is a patch to fix the mb linking problems on AIX. As a nice side effect it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so (all shlibs that are not postmaster loadable modules). Please apply to current (only affects AIX). The _LARGE_FILES problem is unfortunately still open, unless Peter has fixed it per his recent idea. Zeugswetter Andreas SB SD 2002-10-09 20:21:54 +04:00			`$ lslpp -l bos.adt.libm`
