Re: [B.A.T.M.A.N.] batman-adv bug...

Distributions like Gentoo or Debian have to strip the options regarding the optimisation levels and debugging information to fulfil their policies. There is currently no valid reason why the Makefile should override it.

Signed-off-by: Sven Eckelmann sven@narfation.org --- This patch depends on other patches submitted earlier: - batmand: Fix FTBFS on second build attempt - batmand: Remove obsolete creation of source packages - batmand: Remove subversion/svk revision information - batmand: Use nproc to get number of available processors

Distributions like Gentoo and Debian have policies which make it necessary to use some kind of environmental variable to control the parallel build.

New subject: [B.A.T.M.A.N.] [PATCH 04/14] batmand: Directly specify objects in Makefile

The information about header and source files aren't needed by the Makefile. Only the dependencies to headers provide useful information, but these are automatically included by the generated *.d files.

Normally makefile targets should create an output with the same name as the target. It is necessary to mark them as PHONY to prevent that the virtual target like all, clean or install aren't executed when a file with the same name exists.

It is possible that a build environment specifies the CC different than gcc (for example gcc-4.6). The Makefile should only set it when the compiler wasn't explicitely set.

User expect a specific naming inside makefile rules which they can modify by changing environment variables or providing them explicitely as parameters of the make call. The naming was extracted from the gnu make standard rules database.
