#53782 — Bug#822666: linux-headers-3.16.0-4-amd64: deprecated syntax in linux-headers Makefile

Package: linux-headers-3.16.0-4-amd64
Version: 3.16.7-ckt20-1+deb8u4
Severity: normal

Dear Maintainer,

When installing a linux-headers package, a Makefile is installed for compiling
external modules (e.g. /usr/src/linux-headers-3.16.0-4-amd64/Makefile)

the syntax in this Makefile is not compatible with the version of make in
jessie (4.0-8.1)

the symptom is the following message when compling an external module:

Makefile:10: *** mixed implicit and normal rules: deprecated syntax

the problem is fixed with the following patch:

herbelot@ascain:tmp$ diff -Nau Makefile.ori Makefile.new
--- Makefile.ori        2016-04-25 16:32:15.340304128 +0200

 Makefile:;
-$(cmd) %/: all
+$(cmd): all
+       @:
+%/: all
        @:

The patch is also applicable to more recent versions of the package (for
example
the patch is valid for linux-headers-4.6.0-rc3-amd64_4.6~rc3-1~exp1_amd64.deb)

Dear Maintainer,

The problem cannot be solved by importing a more recent version of the 
Linux kernel: the problem comes from a specific Makefile, which is only 
present in Debian

For example, the linux-headers-4.6.0-rc3-amd64_4.6~rc3-1~exp1_amd64.deb 
package, which is quite recent contains a Makefile with the same error:

/usr/src/linux-headers-4.6.0-rc3-amd64/Makefile:

----%----
  1	VERSION = 2
  2	PATCHLEVEL = 6
  3	MAKEARGS := -C /usr/src/linux-headers-4.6.0-rc3-common 
O=/usr/src/linux-headers-4.6.0-rc3-amd64
  4	MAKEFLAGS += --no-print-directory
  5	.PHONY: all $(MAKECMDGOALS)
  6	cmd := $(filter-out all Makefile,$(MAKECMDGOALS))
  7	all:
  8		@$(MAKE) $(MAKEARGS) $(cmd)
  9	Makefile:;
10	$(cmd) %/: all             <=======================
11		@:
----%----

The problem comes from line 10 which contains two types of targets.

Then I do not think the initial problem is solved by switching to a more 
recent version of the kernel (indeed the problem is also present in an 
even more recent of the kernel).

	Best regards

	Thierry

Please read the changelog that was included in the previous message.
