2014-10-02kbuild: simplify build, clean, modbuiltin shorthandsMasahiro Yamada3-4/+4
$(if $(KBUILD_SRC),$(srctree)/) was a useful strategy to omit a long absolute path for in-source-tree build prior to commit 890676c65d699db3ad82e7dddd0cf8fb449031af (kbuild: Use relative path when building in the source tree). Now $(srctree) is "." when building in the source tree. It would not be annoying to add "$(srctree)/" all the time.

2014-10-02kbuild: arm: Do not define "comma" twiceMasahiro Yamada2-4/+0
The definition of "comma" exists in scripts/Kbuild.include. We should not double it. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Michal Marek <mmarek@suse.cz>
2014-10-02kbuild: remove obj-n and lib-n handlingMasahiro Yamada4-7/+5
Kconfig never defines CONFIG_* as 'n'. Now obj-n is only used in firmware/Makefile and it can be replaced with obj-. No makefile uses lib-n. Let's rip off obj-n and lib-n.

2014-10-02kbuild: remove unnecessary variable initializaionsMasahiro Yamada18-69/+0
Clearing obj-y, obj-m, obj-n, obj- in each Makefile is a useless habit. They are non-exported variables; therefore they are always empty whenever descending into each subdirectory. (Moreorver, obj-y and obj-m are also set to empty at the beginning of scripts/Makefile.build) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Peter Foley <pefoley2@pefoley.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
2014-10-02kbuild: remove unnecessary "obj- := dummy.o" trickMasahiro Yamada3-7/+0
In these Makefiles, at least one of "obj-y" and "obj-" is non-empty, hence built-in.o is always created without such a trick.

2014-10-01kbuild: handle C=... and M=... after entering into build directoryMasahiro Yamada1-31/+29
This commit avoids processing C=... and M=... twice when O=... is also given. Besides, we can also remove KBUILD_EXTMOD="$(KBUILD_EXTMOD)" in the sub-make target.

2014-10-01kbuild: use $(Q) for sub-make targetMasahiro Yamada1-2/+1
Since commit 066b7ed9558087a7957a1128f27d7a3462ff117f (kbuild: Do not print the build directory with make -s), "Q" is defined above the sub-make target. This commit takes advantage of that and replaces "$(if $(KBUILD_VERBOSE:1=),@)" with "$(Q)".

2014-10-01kbuild: fake the "Entering directory ..." message more simplyMasahiro Yamada1-11/+8
Commit c2e28dc975ea87feed84415006ae143424912ac7 (kbuild: Print the name of the build directory) added a gimmick to show the "Entering directory ...". Instead of echoing the hard-coded message (that is, we need to know the exact message), moving --no-print-directory would be easier.

2014-09-23kconfig/lxdialog: get ncurses CFLAGS with pkg-configBjørn Forsman1-1/+5
This makes "make menuconfig" also work on systems where ncurses is not installed in a standard location (such as on NixOS). This patch changes ccflags() so that it tries pkg-config first, and only if pkg-config fails does it go back to the fallback/manual checks. This is the same algorithm that ldflags() already uses.

2014-08-22kconfig: nconfig: fix multi-byte UTF handlingBrian Norris1-1/+2
Currently, Kconfig descriptions that use multi-byte UTF-8 characters (such as MTD_NAND_CAFE) will have their menu entries dropped from the 'make nconfig' ncurses menu, and all subsequent entries in the same window will be omitted. This seems to be due to the ncurses 'menu' library, which does not traditionally handle UTF-8 >8-bit characters properly. The ncursesw library ('w' is for "wide") is written to handle these UTF-8 characters, and is practically a drop-in replacement at the source level. Use it by default, if available.

2014-08-20kbuild: Make scripts executableMichal Marek23-0/+0
The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. Signed-off-by: Michal Marek <mmarek@suse.cz>
2014-08-19kbuild: remove redundant clean-files from scripts/kconfig/MakefileMasahiro Yamada1-1/+0
Now mconf, qconf, gconf, nconf are always added to hostprogs-y. Files added to hostprogs-y are removed by "make clean". Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

2014-08-19kbuild: handle the dependency of multi-objs hostprogs appropriatelyMasahiro Yamada1-2/+4
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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
2014-08-19kbuild: handle multi-objs dependency appropriatelyMasahiro Yamada2-6/+13
The comment in scripts/Makefile.build says as follows: We would rather have a list of rules like foo.o: $(foo-objs) but that's not so easy, so we rather make all composite objects depend on the set of all their parts This commit makes it possible! For example, assume a Makefile like this obj-m = foo.o bar.o foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this patch, foo.o depends on all of foo1.o foo2.o bar1.o bar2.o. It looks funny that foo.o is regenerated when bar1.c is updated. Now we can handle the dependency of foo.o and bar.o separately.
