Re: lib32

[Francesco Pietra <frapietra@alice.it>]

I must confess that I was not aware that amd64 etch provides /lib32 
and /usr/lib32. However, I did no IA installation, link, no export. Should any 
exist in my installation (tell me what to search and how) it is [a bug of] 
the system. I have reinstalled amd64 etch raid1 anyway to rule out any 
mistake with the mode of installation or repositories. I detected no mistake.

As to my problem, under this light, where to put Open Motif in order that 
OpenGL is OK? Under /lib32 or /usr/lib32, or under a 32bit chroot, should I 
decide for the moment to run my 32bit application mentioned below? That is, 
is any advantage with chroot, except perhaps upgrading? Ideally, compile the 
package libmotif3 and my application at 64bit.

At any rate, I was surprised to see (from the lists) acute interest for kde,  
open office and other application at 64bit, while the tools for OpenGL have 
not yet been included (or demanded, except by myself). I find it curious 
because the graphics for computational molecular packages is in OpenGL and 
there are good reasons to move from 32bit to 64bit for heavy computations as 
quantum mechanics involves. In contrast, why running openoffice kde and so on 
at 64bit? to write a traditional letter or e-mail at doubled floatpoint?

As this is a list, is anyone aware of linux 64bit that provides OpenGL tools?

Thank you
