foo.c, bar.c and a makefile

should actually be pretty much the same as what you are doing. only 
that i have this exact constellations of files working fine on osx 
with gcc 4.0.1.

will have to check what linker that used, though

same result as given in my example

I seem to remember from last time we tried this... there's a special 
linker tool required on OS X.

But, it was a while ago, so I could be wrong.

i think my attempt was linking with GNU ld

So, I just wanted to post the doc above... and see if there's anyone 
who wants Host-Lib on OS X and is willing to solve the problem in 
some reasonable way.

I think the reasonable way is to get you a reasonable linker.

I assume you are on OSX 10.4 ("Tiger")?

right

So, you're telling me that everyone who built software for 10.4 used 
a bad linker?

libtool -- the name I was trying to remember

No, I'm just saying that for those set of command line flags, your 
linker behaves strange.

It's concatenating the objects. An old lazy method of lib building.

How did you install GCC? Via Xcode?

And, I mean lazy both ways. ;)

Yes, Xcode.

Perhaps I can cross build the lib from a linux box... ?

Yes, but that's a lot of work.

Might be worth it.

Would you mind upgrading to Xcode 2.5?

What's required to go to 2.5? Most tools are dead-ended for 10.4.

2.5 should work on 10.4.

I'm pretty sure that's what I used to build the above sample.

Does Xcode have an update button?

No idea.

Here;s a direct link:

So, 2.5 worked for you?

(You'll need an "Apple ID".)

Unfortunately I don't have the exact machine I tried not handy at 
the moment. But I know it was a 10.4 OSX and I know that the above 
"exports.tar.gz" worked.

I'm pretty sure I used the most recent Xcode available for Tiger, 
which seems to be 2.5.

odd msg in login...

This Apple ID has been disabled for security reasons.

I can have Cindy setup a new devl account... but I suspect this will 
all lead down a road that will cost me a lot of time.


I don't see why cross building from Linux or BSD is a problem.  It's 
just a lib, not an app.

Because setting up the cross compiler is a lot of work.

You need to download and rip apart Xcode, amongst other things.

(Check your PM.)

How would I know? I  built such a cross-compiler before:
$ uname -sm
Linux i686
$ gcc -dumpmachine
i486-linux-gnu
$ i686-apple-darwin9-gcc -dumpmachine
i686-apple-darwin9

Right, but it's just elf, isn't it?

The only dependencies are minimal.

OSX is Mach-O.

Ah... so there's the rub.

Ever try an elf-to-mach-o converter?

Nope.

But I only know of one, in any case.

And that'd still need a Mach-O linker.

(Agner's "objconv" is the one I once stumbled across: http://www.agner.org/optimize/)

I'm not seeing my Dev_Event device's RDC_QUIT vector being called 
when I exit r3 with a 'q' from the command line. I do see the RDC_INIT 
vector being called.
