I have Fedora 8 installed from a magazine's DVD, and built a kernel from 2.6.24 source downloaded from a kernel mirror. I got a 32-bit i686 kernel.

I am trying to build a 64-bit kernel from that source with no luck.

make xconfig does not appear to offer x86_64 as an option for processor type. .config has the following lines:

# CONFIG_64BIT is not set
CONFIG_X86_32=y
# CONFIG_X86_64 is not set
CONFIG_X86=y

If I try to change them manually they get changed back when I run make.

How do I build a kernel for x86_64?

The processor is an AMD Athlon 4600+

TIA
Jim

First and foremost, you have the 32-bit version of Fedora 8 installed, building a 64-bit kernel will be useless. To start with you do not have the tools and components required to build or support a 64-bit kernel.

As a suggestion, please download and install the 64-bit OS first.

Thanks. I'll do that.
