question about configure

question about configure

[Yongming wei]

hi all,
 
I will simulate some applications for arm7 in my
redhat linux box, and I am confused when compiling
sid. I remember when building gcc and binutils for
arm, I use --target=arm-elf when running configure as
below:

../src/configure  --target=arm-elf

My question is if I need --target=arm-elf when
compiling sid, I think sid is only an simulator
running in linux, it will not create any code for arm
cpu, but the configure for sid have the --target
parameter, what it is used for?

I have tried building sid with --target=arm-elf and
without this parameter, all can complete.

thanks,

No, you don't need it, but it doesn't hurt either.

By default, sid will configure itself to provide a
simulation for processor architectures it supports.  If
you supply "--target=arm-elf", sid will configure itself
to support just that single target and disable the others.
This means that the resulting sid tree would be somewhat
smaller and somewhat faster to build, but less functional.
