Re: [Ltib] Tlib: using local files to re-build

[Stuart Hughes]

Hi Simon,

Please keep all messages on the list.

In step 2, you need to enter the directory where you have _your_ kernel 
source for the platform you want to build (e.g. the one you downloaded 
and are working on).

In step 3 you don't need to change anything.

In step 4: you are working on some particular target (which one?).  This 
will have a directory config/platform/_target_.  In there you will find 
a kernel config file, which may be usable.  If not you should copy 
something suitable there OR deleting the entry for the kernel config 
file may be okay as there is a default search for kernel config files 
within the kernel source.  This cannot be guaranteed though as platforms 
do not orthogonally place or name their "defconfig" files.

Regard, Stuart
