This brings up the whole issue of 32-bits vs 64-bits. In the current Linux From
Scratch book, I wrote:
"Some other facts about a 64-bit systems need to be added here. When compared to
a 32-bit system, the sizes of executable programs are slightly larger and the
execution speeds are only slightly faster. For example, in a test build of
LFS-6.5 on a Core2Duo CPU based system, the following statistics were measured:
Architecture Build Time Build Size
32-bit 198.5 minutes 648 MB
64-bit 190.6 minutes 709 MB
As you can see, the 64-bit build is only 4% faster and is 9% larger than the
32-bit build. The gain from going to a 64-bit system is relatively minimal. Of
course, if you have more than 4GB of RAM or want to manipulate data that exceeds
4GB, the advantages of a 64-bit system are substantial."
Everything I've tried works fine in both a 32-bit system and 64-bit system.
I still believe that a 64-bit system for most users is unnecessary. However,
it's probably relatively difficult to find a new hardware system that does *not*
support 64-bits. Eventually, I think we'll see support for 32-bit systems drop
away like we saw support for real mode software dropped. The current mixed-mode
systems that have /lib and /lib64 are an inelegant hack and I think we will see
less and less need for any 32-bit libraries. Even today, the only real need for
32-bit libraries is to support proprietary code like flash and other older code.
Nvidia already has 64-bit versions and Adobe is going that way with the flash
player. The only other proprietary code I run is vmware and I'm pretty sure
that comes in native 64-bit versions too.
