Re: lib32

Sent again to make clear my aim: having a pure 64bit once I can run the few 
applications I nedd (two in total) at 64bit, without having to reinstall the 
OS. What I am trying to avoid is to make the OS "less pure" by dealing the 
wrong way with 32bit libraries and applications.
thanks again

I posed this morning the question of OpenGL for 64bit to Gerd Knorr. However, 
may I ask about the strategy to follow for 32bit applications in debian amd64 
etch (installed on separate partitions /, /usr/. /var/ /tmp, and swap, ith 
RAID1) at the current stage of development?

1) make use of /lib32 and /usr/lib32 as furnished on the installation. 
performing an 'apt-get install ia32-libs' to get support for OPenGL (which is 
what my applications require in addition to X-system) and add
 export XLOCALEDIR=/emul/ia32-linux/usr/X11R6/lib/X11/locale" to the FAQ for 
32bit programs needing X locales. 

2) Installing a Debian IA32 chroot system
 First you need to install a IA32 base system into a chroot. You can do this 
with the debootstrap command: 
debootstrap --arch i386 sid /var/chroot/sid-ia32 http://ftp.debian.org/debian/
To install a few more libraries you can change into this chroot and 
install/update packages with apt-get: 
chroot /var/chroot/sid-ia32
apt-get install libx11-6

Option (2) from your HOWTO was that I was aimed at, until I discovered with 
surprise that some 32bit libraries are furnished on installation as described 
above. Now, if I opt for solution (2), what shoul I do with the 
installed /lib32 and /usr/lib32?

All that as a temporary solution until debiam amd64 develops further and I 
succeed in compiling at 64bit all application that I need for molecular 
mechanics as an input to mpqc.

I am used at planning before moving; although not an expert in computer 
science, I am trying to get a clear knowledge of the boxes where to move.

Thanks for help and for your kind patience.
