kbuild: handle the dependency of multi-objs hostprogs appropriately

2014-08-19T08:26:20+00:00

Assume we have a Makefile like:

hostprogs-y := foo bar
foo-objs := foo1.o foo2.o
bar-objs := bar1.o bar2.o

Without this commit, the host program foo depends on all of
foo1.o foo2.o bar1.o bar2.o.

This commit allows to handle the dependency of each host program
separately.

kbuild: clean-up and bug fix of scripts/Makefile.host

2014-07-16T15:15:26+00:00

Assume we have a Makefile like this:

  hostprogs-y := foo
  foo-cxxobjs := bar/baz.o
  foo-objs := qux/quux.o

In this case, Kbuild creates bar/ directory,
but fails to create qux/ directory.

This commit re-writes directory creation more simply,
fixing that bug.

kbuild: clean up scripts/Makefile.host

2014-07-16T15:15:26+00:00

The directory creation can be more simplified by two levels.

[1] Drop $(dir ...)

 $(dir $(f)) always returns non-empty string.

So, $(if $(dir $(f)),$(dir $(f)) is equivalent to $(dir $(f)).

[2] Unroll $(foreach ...) loop

$(dir ...) can take one or more arguments and returns a list of
directories of them.

$(foreach f, $(progs), $(dir $(f))) can be unrolled as $(dir $(progs)).

kbuild: drop shared library support from Makefile.host

2014-07-16T15:15:26+00:00

The shared library feature in Makefile.host is no longer used.
Rip it off to keep the build infrastucture simple.

Update Documentation/kbuild/makefiles.txt too.
The section "4.3 Definition shared libraries" should be removed
and the following sections should be re-numbered.

kbuild: fix a bug of C++ host program handling

2014-07-16T15:15:25+00:00

The comment claims:
  C++ executables compiled from at least one .cc file
  and zero or more .c files

But C++ executables with zero .c file fail in build.

For example, assume we have a Makefile like this:

  hostprogs-y := foo
  foo-cxxobjs := bar.o

In this case, foo is treated as host-csingle
and Kbuild tries to search non-existing foo.c source.
