Confusion about 32/64-bit user space
I am a tad confused here, so bear with me...
Okay: I have an Ultra 10, on which I've installed Debian 3.0r0. As I
understand it, the kernel operates in 64-bit mode, while any programs I
write and run operate in 32-bit mode. Is that correct?
Is there anyway to change user space such that it is 64-bit?
This came up when I built gcc 3.2; the configure script couldn't figure out
my installation. As it is explained to me by someone in the gcc mailing
list, what I managed to build was a 32-bit version of the compilers, given
that my user space is 32-bit.
Why isn't user space 64-bit by default? Is it that many GNU/Linux programs
aren't compatible with 64-bit?
