How to disable building of -dbg Debian package?

How to disable building of -dbg Debian package?

[Aleksander Alekseev]

Hello.

I'm building Linux kernel like this:

```
cp /boot/config-$(uname -r) ./.config
make olddefconfig
make -j4 deb-pkg LOCALVERSION=-custom
```

Resulting files are (for 4.7.0 kernel):

```
   966694 linux-firmware-image-4.7.0-custom_4.7.0-custom-1_amd64.deb
 10316460 linux-headers-4.7.0-custom_4.7.0-custom-1_amd64.deb
 45639036 linux-image-4.7.0-custom_4.7.0-custom-1_amd64.deb
471400164 linux-image-4.7.0-custom-dbg_4.7.0-custom-1_amd64.deb
   851664 linux-libc-dev_4.7.0-custom-1_amd64.deb
```

Compilation takes about an hour and most of this time is spent on
creating a -dbg package which I don't install anyway. Frankly I don't
think this package is very useful since Linux kernel can't be built
with -O0 option [1].

Is it possible to disable building of this package?

Maybe the relatively new "bindeb-pkg" target is closer to what you want?
See "make help" for all alternatives.

Hi Aleksander,

disable CONFIG_DEBUG_INFO and -dbg package will not be built.
But this package can be very useful, if you are going to debug kernel
code. SystemTap, crash, makedumpfile need debug symbols.

Thanks for your replies!

Indeed, commenting CONFIG_DEBUG_INFO option disables building -dbg
package. Just what I needed!

bindeb-pkg doesn't disable building -dbg package, but it helps in
another way. When this target is used only .deb package are built,
all .tar.gz archives, .changes and stuff like this are disabled. It
also speeds up building a little, thanks!
