[gentoo-user] Append string on Kernel builds

[gentoo-user] Append string on Kernel builds

[reader]

In the first section during a `makeconfig' session, there is a line
(the second one) that says:

  Local Version - append to kernel release

I like to use that and put `-$MYHOST' as string.  I wondered if there
is any way to set a numericly incrementing string.  Maybe some trick
syntax that can go in that spot?

The build system does that automatically as long as you don't "make mrproper", 
see "uname -a" output.

HTH...

You can backup .version

No.. its not the same as what I'm talking about.  When you set the
item in menuconfig:
  General Setup/Local Version [...]

The string you set there  is appended to that actual build product
like vmlinuz-2.6.26-gentoo-$HOST

The vmlinuz that gets sent to /boot/ when you say `make install' is
named that way, along with the config-XXX and System-XXX that is moved
there.

Keeps things kind of tidy in /boot/ if you are mucking around with
several kernels.

What I asked was if there is some tricky syntax I could use on that
kernel setting that would do:  linux-2.6.26-gentoo-$HOST-N
Where N is an incremented number every time I build the kernel without
running `mrproper'.

Not quite what you are asking, but would appending a timestamp to the
name work instead? It would pretty much guarantee a different name for
every build.

Just a thought,

A timestamp would be fine.  What syntax would I use on the kernel
config item:

  inside menuconfig => General Setup/Local Version [...]  

to get a timestamp?

How about an external tool?  I use sed to fill in LOCALVERSION, e.g.

  V=$( date "+%m%d.%H%M" )
  cp -p .config .config.old
  sed s/LOCALVERSION.*/LOCALVERSION=\"$V\"/ < .config.old > .config

  make vmlinux modules modules_install

HTH,

David

Ahaa ... that looks just like what I'm after... I didn't know about
the env variable LOCALVERSION.

I haven't actually tried this yet but it looks like what I'm after..
Thanks

cd /usr/src/linux
echo "-${MYHOST}-" >localversion1
ln -s .version localversion2

The build system adds the contents of any localversion* files it finds,
and it also increments .version.
