FAQ
Solution:

I discovered gcc does NOT properly accept/respect "OBJECT_MODE=64"
and tries to assemble 32-bit executables. Bzzzzt....!


export CFLAGS='-maix64' was the flag that fixed it...

( Correction for last mail: )

Strike the GNUMake comment below. I was referring to GCC 3.4.3

Status as of now:

- Can do without flex/bison (because I am not pulling from CVS,ie)
- Can ( theoretically ) do without readline and zlib via the
--without flags, but agree that no practical implementation
would want to do this
--GNU Make 3.4.3 _seems_ to be working fine (my SA finds anything
above 3.3.x "provocative"; I demurred.)

-- Can build 32-bit executables -- but I don't want these.

-- Can NOT build the 64-bit XCOFF executables I do want. (see
the PS below for specifics )


Have tried various combinations of:


OBJECT_MODE=64
-Xlinker -b64 -Xlinker -bbibtoc
--enable-aix64

If "GNU Make 3.80" will solve this, I'll fight that battle. But
I suspect the problem is my limited understanding of 64bitAIX
enviroments and possibly a bad OS build environment.



Thanks for any thoughts on this,

Christopher Browne <cbbrowne@acm.org> writes:
It may be handy for you to know what sorts of things we have found
useful to compile and install in addition to PostgreSQL on AIX:
1. GNU readline 5.0
2. zlib 1.2.1
3. GNU Make 3.8.0
4. m4 1.4
5. GNU flex 2.5.4
6. GNU Bison 1.875
You definitely do need GNU make if you are going to compile Postgres, and you want to have readline and zlib if you want to build fully functional psql and pg_dump/pg_restore (respectively).

In theory you should not need m4, flex, or bison to build Postgres from a distribution tarball (though you likely will need them to build from a CVS pull). A tarball should include all the derived files that you'd otherwise need these programs to build. If you've found otherwise please let us know ...
