Cross-architecture compiling

[Jan Dušátko]

Hi,

I would like to ask people in this conference for advice regards
cross-architecture compiling.
Right now I have 32-bit system, where I need to boot over TFTP/NFS diferrent
architectures (i386/AMD64). I need to populate appropriate directory
structure using some "generalized" kernel configuration, each platform have
thein own kernel.conf.

I did those steps bellow, but this not work. Can someone help me?

Regards

Jan
