- riotboot targets should not be needed for riotboot application
so dont include it.
- also fixes#12003 by not setting FLASHFILE = $(RIOTBOOT_EXTENDED_BIN)
when compiling riotboot application
If CC_NOCOLOR was not set by the user it was set according to the
terminal support of colored output.
But since CC_NOCOLOR is also used to set `-fdiagnostics-color` flags
this means changing `CFLAGS` according to terminal support of colored
output.
This is not needed for `-fdiagnostics-color` since this option is by
default `auto` if the compiler supports colored output, and `auto`
means it will only use color when standard error is a terminal.
In Windows setups using MSYS environment variables which start with a
slash get the 'root path' added. This adds a second slash to the content
of KCONFIG_AUTOHEADER_HEADER, so the first one is escaped when building
on those platforms.
Having the definitions sit in the `net/gnrc/sixlowpan/frag.h` header
does not make much sense, when using Selective Fragment Forwarding
(and the fragmentation buffer already includes a
`net/gnrc/sixlowpan/frag/stats.h` header), so they are moved to their
own header. Since with this change it makes more sense to have the
statistics stored in their own sub-module, the pseudo-module is also
actualized.
This adds a check to decide if Kconfig should run on a build. It will
run if any of the following conditions is true:
- A file with '.config' extension is present in the application folder
- A 'Kconfig' file is present in the application folder
- A previous configuration file is present (e.g. from a previous call to
menuconfig)
- menuconfig is being called
This assumes that Kconfig will not generate any default configurations
just from the Kconfig files outside the application folder (i.e. module
configuration via Kconfig is disabled by default). Should this change,
the check would not longer be valid, and Kconfig would have to run on
every build.
Introduce a new variable 'BOARDSDIR' to use when referencing the base
boards directory.
This is a transition to allow defining external boards while still using
the `RIOT/boards` directory for like `boards/common` for example through
'RIOTBOARD'.
- The autoconf.h header file, generated with the current Kconfig
configurations, is added as a build dependency.
- autoconf.h depends on the proper tool (genconfig) and a Kconfig.dep
which contains the dependencies for the given application and board,
this is generated from $(USEMODULE).
- The menuconfig target is added, to allow the configuration of modules
using the Kconfig system.
When CCACHE_BASEDIR variable is set, ccache rewrites absolute paths into
relative paths before computing the hash that identifies the compilation
for all the paths under that directory.
The problem is that those paths are also used when the compiler is
called, so the generated dependency files (*.d) will have a relative
path to the object files, and thus, it will not match our rule for
compiling (we use absolute paths). As dependency files define the
targets this way, any change on its dependencies (e.g. an included
header file) will not re-trigger a build.
