Weird strings in kernel uname when cross-compiling

Weird strings in kernel uname when cross-compiling

[A. Nolson]

Hi all,

 anybody knows why every time I cross-compile my kernel (Denx 4.2 
cross-compiling chain ) I get an extra string in my vermagic like this

2.6.24-rc3-gd7ed933b-dirty

when my kernel's ( secretlabs 2.6.24-rc3) makefile has this parameters:

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 24
EXTRAVERSION = -rc3

(So no -gd7ed933b-dirty anywhere... )

 Having that is a bit annoying when I try to natively compile modules, 
so I need to workaround it by copying  that extra string into my other 
Makefiles. Anybody knows how to get rid of it?

It gets added on if you are building from a git repository and you have
CONFIG_LOCALVERSION_AUTO set.  Disable that and it should go away.

(BTW, a quick grep in the top level Makefile would have told you all
that.)

It seems you don;t use the kernel's Makefile to build your modules,
which is a problem in itself. You should fix that first.

Note that disabling this is strongly  discouraged  as  the  "annoying
extra  string"  is  extremely  useful  -  it allows for exact version
ideltification of the kernel you are using, including the  fact  that
you have modified but uncommited files in your tree.

Best regards,
