Description Sven Vermeulen 2009-03-31 17:54:57 UTC

E-mail I received:

"""
Why no one has mentioned here:
http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml?part=1&chap=7
that the sparc kernel needs to be compiled using:
# CROSS_COMPILE=sparc64-unknown-linux-gnu- make
Can you update the handbook?

Sparc team: is this correct?

Yes, for kernel >= 2.6.25

For reference see bug #214765, kernel-2.eclass also has an elog-message about this.

FWIW, here is a patch to add the necessary environment variable for 64-bit kernel compilation.
