Well, it uses a Mach kernel.

Out of the box when I run config, it says (which is to be expected):

checking host system type... configure: error: can not guess host type;

you must specify one

<fontfamily><param>Helvetica</param>So? That really doesn't help at all. I guess I didn't say it well enough in my post but I have no idea how to use the template or configure system beyond typing:

./configure

and watching it do it's magic. My question is how do I setup a template that does the "right thing" or do a manual install so that i can get it to compile on Mac OS X.

Thanks

I'm sure someone can answer this better than me...

Mac OS X uses the Mach kernel and a version of BSD (can't recall which). Is
it possible one of the existing templates may work? I believe sendmail uses
the same sort of thing for host ype, and they have sendmail compiled on OS X
(comes with it), so if it comes to the point where no one else on the
postgres list can help, might be possible to dig up something from sendmail
users.

As for choosing a template, unfortunately, again, someone else might help
you more.

Sorry only have ideas on where to look and not any actual solutions.

Thanks Adam. Yeah, I know that it uses a mach kernel and variant of freebsd runs atop the kernel. I would attempt the FreeBSD template but the other snag is that it has to compile on PowerPC. I think you have a good idea and I'll download the sendmail source tarball from the darwin site and look into it's build process and see if I can steal any tidbits from it. I'm also going to post on the darwin list. I was just hoping someone here would have already done all the dirty work for me :-)

thanks again,

mike

Great!

First, go to http://subversions.gnu.org/cgi-bin/cvsweb/config/ and try the
latest config.guess, to see if it recognizes your platform. I think it
should.

Then, download a development snapshot from
ftp://ftp.postgresql.org/pub/dev/postgresql-snapshot.tar.gz. You can try
to get 7.0 to work as well, but we can't make any use of patches against
it.

Stick the working config.guess (I hope) in place of the existing one.

There are several places in the source that need platform specific
information:

1. the "template" in src/templates

2. the port makefile in src/makefiles

3. the dynamic loader in src/backend/port/dynloader

4. spinlock code in src/include/storage/s_lock.h

Look into the existing files for what kind of things need to be put
there. You should probably start from the netbsd ones.

Then, you need to go into configure.in and in the big case statement at
the top (line 57 in current sources) map the config.guess output to some
name that is used by the template files. Probably "macosx" would be a
good choice, but maybe "netbsd" would work out of the box?

(I've been thinking about merging the openbsd, freebsd, and netbsd
templates into one, so maybe macosx doesn't need to be a separate one.)

Let us know if you have questions.

FreeBSD template seems like it'd be a good starting point. 7.0.*
will probably not work on PPC unless you compile with optimization
level -O0, so tweak CFLAGS in the template that way before running
configure. Otherwise it seems like it'd more or less work --- give
it a shot and let us know how it goes.

BTW, I think the PPC optimization issues are solved in current sources.

From a development perspective it'd be more interesting to hear your

report on what happens with a current nightly snapshot instead of 7.0.2.

Thanks to everyone for giving me a starting point.

here's what I tried so far:
changed the CFLAGS in the src/template/freebsd file to:
CFLAGS='-O0 -pipe'

did
./configure --with-template=freebsd

configure succeeded.

Did a make and started to build. During the build, there were a ton of messages of this type:
../../../../src/include/catalog/pg_type.h:414: stray '\' in program

make exited with this:

cc -c -I../../../src/include -O0 -pipe -Wall -Wmissing-prototypes -Wmissing-declarations -o dynloader.o dynloader.c
dynloader.c:42: header file 'link.h' not found
dynloader.c:43: header file 'dlfcn.h' not found
../../../src/include/dynloader.h:19: header file 'link.h' not found
make[3]: *** [dynloader.o] Error 1
make[2]: *** [port-recursive] Error 2
make[1]: *** [all] Error 2
make: *** [all] Error 2

Not sure if configure didn't move the correct files or if there was something else wrong. I was using the lastest developer snapshot for testing. I also tried it on a stock 7.0.2 source but got the same error.

Any ideas? I'm willing to try and get this working but unfortunately my grasp of the process is pretty weak.

FWIW, you should probably start with "netbsd" rather than "freebsd"
because the FreeBSD code might be rather surprised at finding itself
running on a PPC. (But then again, the *bsd codes are mostly the same
anyway.)

Oh man, they didn't take that old NeXTstep C preprocessor for MacOS X? ;-)

The MacOS X dynloader seems to be somewhat different than FreeBSD's. Try
NetBSD's, or if all fails you can copy over the QNX dynloader files.
That platform doesn't support dynamic loading at all (actually, I think it
does now, but we haven't gotten around to supporting it) so the stub files
should get you to compile at least.
