Re: [NTG-context] osx-64-binaries/minimals
But I have no idea if there is some simple way to hardcode the target architecture into LuaTeX itself. You could check the first few bytes of the LuaTeX binary itself, it has to tell you something about the architecture it was compiled for. That's what file uses in most cases anyway (the magic numbers). By compiling a stupid C program on both 10.5 and 10.6, I see that the first 16 bytes of the executable are, respectively: 10.5: cefa edfe 0700 0300 0200 10.6: cffa edfe 0700 0001 0300 0080 0200 Arthur ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Re: [NTG-context] osx-64-binaries/minimals
If I update the minimals via first-setup.sh I get the 32bit-binaries (luatex) although I'm on Snow Leopard. If I change the binaries myself it works fine and the compilation is notable faster! Andreas, Can you please try one thing? In first-setup.sh you can try to add the following lines (around line 56, after the platforms are being recognized): if test $platform = osx-intel; then # running Snow Leopard or later if test `uname -r|cut -f1 -d.` -ge 10 ; then # working on 64-bit hardware if test `sysctl -n hw.cpu64bit_capable` = 1; then platform=osx-64 fi fi fi And then update the minimals. After that try to paste the same lines to setuptex around line 59, try to run setuptex and try if you get the 64-bit binaries and if they work fine (I can try to do that myself, but I try to avoid rebooting my machine too often). You need to fix setuptex after you update the distribution since updating will change setuptex. If that works for you, I'll fix it.

Re: [NTG-context] osx-64-binaries/minimals
OK, I did a nasty thing. I have patched setuptex to run 64-bit binaries on Snow Leopard. There is only one problem: mtxrun doesn't know that one is running on a 64-bit platform and consequently fetches just 32-bit binaries. Consequently one needs to call mtx-update with --platform=osx-64. I fixed first-setup.sh, but existing Snow Leopard users with 32-bit kernels will have to add that to first-setup.sh themselves ... or we need to revert the change.

Three times the original size since we now support 3 platforms. Any other votes?

We had a lengthy discussion about Snow Leopard. The last message was
Yue Wang's proposal to check for 64-bit compatibility:
The hardware test:
Yue:context yue$ if test `sysctl -n hw.cpu64bit_capable | grep -c 1`
= 1 ; then echo yes; else echo no; fi
yes
The software test:
Yue:context yue$ if test `uname -r|cut -f1 -d.` -ge 10 ; then
echo yes; else echo no; fi
yes
hm, we need to use the methods built in luatex
Someone should check what is returned in the os.uname() return table.
Mine returns
t={
[machine]=x86_64,
[nodename]=...[my ip]...,
[release]=10.0.0,
[sysname]=Darwin,
[version]=Darwin Kernel Version 10.0.0: Fri Jul 31 22:46:25 PDT
2009; root:xnu-1456.1.25~1/RELEASE_X86_64,
}
but I'm booting in 64-bit mode (I need to reboot first to check for
return value in 32-bit mode).
On one hand uname doesn't return anything usable when booting with
32-bit kernel, but on the other hand one probably already runs the
64-bit luatex at the time when mtxrun needs to determine the
architecture.

Well, I doubt you can discover whether you have a totally 32bit software
environment with a 64bit kernel without lots of trickery (but I could
be wrong about that). In any case, os.uname() will give the same results
as the shell command uname.
64bit osx runs 32bit executables (I assume) so you could make the
initial luatex (the one used during install) be a 32bit one, then make
that one decide on which one to use for normal typesetting?

Taco
