 Posted: Thu Oct 01, 2009 1:41 pm Post subject: Confused on kernel compilation [SOLVED] |
 |
|
Hi All,
Built a new system last night and am going through my first amd64 install using the amd64 minimal install CD.
Just compiled the kernel and am told...
| Code: |
Kernel: arch/x86/boot/bzImage is ready (#1)
|
...I would have expected it to have been compiled into the appropriate folder i.e. arch/x86_64/boot/bzImage ?
Any reason why this isn't the case? Has my kernel genuinely been built as 64-bit?
Not set much up yet, but heres the /etc.make.conf
| Code: |
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
CFLAGS="-O2 -march=core2 -pipe"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j3"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.

The solution is about 2 years back....
IIRC in 2.6.24 they merged x86 and x86_64 again to reduce redundant code.
So yes, you have built a 64-bit kernel, but the original lies with the x86 tree. there should be a soft link in x86_64...
hope that clears it up
cheers

No, thats great thanks, I did check for symbolic links between the two but nada.
This is the first x86_64 system I've built, in fact its my first new computer (bar NAS's) since 2001!! 
Cheers for the sanity check, much appreciated

Yeah, I'm familiar with that unfortunately at present I can't yet boot my new kernel to test it!
Going to try sorting that out this weekend (currently installing stuff under a chroot'd env over ssh from work  )

Ahh, I'd checked to see if the directory was sym linked, not the file itself!
