Bug 458616 – ARCH="x86" - usr/initramfs_data.S:1:0: error: CPU you selected does not support x86-64 instruction set

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Raymond Jennings 2013-02-21 16:35:03 UTC]

Tried to build a 64-bit kernel on atom, it failed saying that atom doesn't support 64 bit, which I know isn't true.

Reproducible: Always

Actual Results:  
bogus build error

Expected Results:  
no build error

ARCH="x86"

That certainly won't work.

Please post your `emerge --info' output in a comment.

I figured gcc ought to be able to generate 64-bit code just fine.

[Comment 6 Chí-Thanh Christopher Nguyễn 2013-02-22 14:19:57 UTC]

It is possible to generate 64 bit code, but for that you need to build a 64 bit gcc (using crossdev, or amd64 stage3, or similar).

[Comment 7 Raymond Jennings 2013-03-07 21:32:50 UTC]

I just tried this after doing "crossdev x86_64" and I keep getting the same errors.

Are you guys SURE this is an invalid bug or is there something else I need to do?
