Re: Failure to Install minimals on iBook G3

Re: Failure to Install minimals on iBook G3

[Robert Blackstone]

Thank you, Arthur and Mojca, for your quick and clear response.

It is probably not worth bothering for this particular machine. I have
access to the minimals on several other Macs (including a much older,
not to say ancient PowerMac G4, also on Tiger). So I'm not
particularly needy in this respect.
I rescued this iBook from a garbage dump, in fact there were two of
them, both defect, from which I have been able to make one working
machine, and I just thought that it would have been nice to have
ConTeXt-minimals on it.

But it is puzzling. I never had any problems with two other PPC Macs,
so what makes this one essentially different? (No answer needed.)

Best regards,
Robert Blackstone

I can donate a G4/400, it's just sitting idle under my desk anyway.

I've still my old G3 iBook running 10.4.11 and could compile PPC  
binaries on that - but not very regularly, i.e. you would have to  
remind me if new binaries are needed, and it may last a few days,  
since the iBook is normally stowed away.
I just try the compilation, I guess it'll need some hours on that  
machine...

Maybe you should ask for donations to get a Tiger PPC build machine
for the minimals?

Best

The "nothing can be done" is not entirely true. We should still be
able to compile a new binary on an older machine (yours, for example),
it only makes it very clumsy to compile on several machines.

However, in one way this is a bit weird. We have a non-neglegible
number of PPC users of minimals and nobody has complained about that
problem so far, so nobody was even aware of the problem. Back in May
we had a complaint from Tiger users (on Intel) that we were able to
solve after two days of debugging. So ... there is a hope to fix this,
but only after quite some debugging, if anyone is ready to do the
debugging.


But the other side of the coin is that ... Mac OS X Lion is
approaching with inevitable speed. Once that one is out and installed
on our machines, we'll have serious problems anyway since 10.7 won't
allow cross-compilation for Tiger. And the number of Tiger users is
not neglegible at all ...

As far as TeX Live is concerned, the binaries for PPC are compiled on Panther.

  This is a binary compatibility problem: the LuaTeX executable for Macs
running on PowerPC processors are built on an Intel Mac using a
cross-compilation technique.  I'm afraid nothing can be done at the
moment.

  Yes, for MacTeX (actually TeX Live) the binaries are built on a actual
G3.  But we can't use TeX Live binaries in the Minimals because we need
a more recent LuaTeX.

Failure to Install minimals on iBook G3

[Robert Blackstone]

Hello,
I tried in vain to install the minimals on an old (2003) but still
functional iBook G3, running under OSX 10.4.11. After having received
some 4MB, I get the message: "dyld: incompatible cpu-subtype" plus a
reference to line 103 of first-setup.sh.
Does anybody on this list know what could be done about this. Btw,
this iBook can handle TeX and ConTeXt. I installed MacTeX 2009 and
everything works. But I would prefer the minimals.

Thanks in advance.

Robert Blackstone
