That's right. > 2. I'm building on a 64 bit system, if I follow the book exactly, would this > build yield a 32 bit or 64 bit system? It actually depends on the host OS. If the host OS is 32-bit, the new one will be "pure" 32-bit. If it's 64-bit, the new one will be a "pure" 64-bit system. To make a multi-lib system, you have to compile the libraries needed twice with different parameters. We don't do that in LFS. You also don't need the "other" size libraries if you have the source. You only need them if running a proprietary 32-bit binary on a 64-bit system. > 3. if the answer to question one is 64 bit, is this automatically a multilib > system or are there additional steps that will pave the way to multilib? > > 4. can I use the LFS book to create a 32bit system on a 64 bit OS?
