Host x86_64, Can I compile for x86_32???


Hello,

I have a laptop with dual core, and OS Suse 11.0 x86_64.

My question is, Can I compile programs and kernel for x86_32 ???

Before this question, I have looked for information in google and for example I can configure gcc for 32 bits:

./configure --host=x86_64-pc-linux --build=x86_64-pc-linux --target=i386_pc-linux-gnu

Best reagards

Yes, cross compile is possible, as far as I know, the only thing to remember is that you need a copy of binutils for the target system you intend to compile to, so both, binutils and gcc should be configured to use the --target option

Or you can just install multilibs, chroot to a 32bit environment and use 32bit gcc

Or you could run a 32bit virtual machine for my 32bit development, it seems like its a hassle but you don't have to futz with anything once its setup and you can compile it in the environment/os you want.

No it is not necessary, but then you have to cross compile.
