kconfig: do not require pkg-config on make {menu,n}config

2018-09-02T17:13:48+00:00

Meelis Roos reported a {menu,n}config regression:
 "I have libncurses devel package installed in the default system
  location (as do 99%+ on actual developers probably) and in this
  case, pkg-config is useless.  pkg-config is needed only when
  libraries and headers are installed in non-default locations but
  it is bad to require installation of pkg-config on all the machines
  where make menuconfig would be possibly run."

For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.

kconfig: add build-only configurator targets

2018-08-22T14:21:37+00:00

Add build-only targets for build_menuconfig, build_nconfig,
build_xconfig, and build_gconfig.
(targets must end in "config" to qualify in top-level Makefile)

This allows these target to be built without execution (e.g., to
look for errors or warnings) and/or to be built and checked by sparse.

Merge tag 'kconfig-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

2018-08-15T19:50:10+00:00

Pull Kconfig updates from Masahiro Yamada:

 - show clearer error messages where pkg-config is needed, but not
   installed

 - rename SYMBOL_AUTO to SYMBOL_NO_WRITE to reflect its semantics

 - create all necessary directories by Kconfig tool itself instead of
   Makefile

 - update the .config unconditionally when syncconfig is invoked

 - use 'include' directive instead of '-include' where
   include/config/{auto,tristate}.conf is mandatory

 - do not try to update the .config when running install targets

 - add .DELETE_ON_ERROR to delete partially updated files

 - misc cleanups and fixes

kconfig: create directories needed for syncconfig by itself

2018-07-25T14:25:30+00:00

'make syncconfig' creates some files such as include/config/auto.conf,
include/generate/autoconf.h, etc. but the necessary directory creation
relies on scripts/kconfig/Makefile.

To make Kconfig self-contained, create directories as needed in
conf_write_autoconf().

This change allows scripts/kconfig/Makefile cleanups; syncconfig can
be merged into simple-targets.

kconfig: remove unneeded directory generation from local*config

2018-07-25T14:25:29+00:00

Commit 17263baf958b ("kconfig: Create include/generated for
localmodconfig") added the 'mkdir' line because local{yes,mod}config
ran streamline_config.pl followed by silentoldconfig at that time.

Since commit 81d2bc227305 ("kconfig: invoke oldconfig instead of
silentoldconfig from local*config"), no sub-directory is required.

kconfig: check for pkg-config on make {menu,n,g,x}config

2018-07-17T16:18:09+00:00

Each of 'make {menu,n,g,x}config' uses (needs) pkg-config to make sure
that other required files are present and to determine build flags
settings, but none of these check that pkg-config itself is present.
Add a check for all 4 of these targets and update
Documentation/process/changes.rst to mention 'pkg-config'.

kbuild: Rename HOST_LOADLIBES to KBUILD_HOSTLDLIBS

2018-07-17T16:18:05+00:00

In preparation for enabling command line LDLIBS, re-name HOST_LOADLIBES
to KBUILD_HOSTLDLIBS as the internal use only flags. Also rename
existing usage to HOSTLDLIBS for consistency. This should not have any
visible effects.
