The tested targets are the followgin ones: * tools * distribution * sets * release The remaining NetBSD targets have not been disabled nor tested *at all*. Try them at your own risk, they may reboot the earth. For all compliant Makefiles, objects and generated files are put in MAKEOBJDIR, which means you can now keep objects between two branch switching. Same for DESTDIR, please refer to build.sh options. Regarding new or modifications of Makefiles a few things: * Read share/mk/bsd.README * If you add a subdirectory, add a Makefile in it, and have it called by the parent through the SUBDIR variable. * Do not add arbitrary inclusion which crosses to another branch of the hierarchy; If you can't do without it, put a comment on why. If possible, do not use inclusion at all. * Use as much as possible the infrastructure, it is here to make life easier, do not fight it. Sets and package are now used to track files. We have one set called "minix", composed of one package called "minix-sys"

# Rules used when building a GNU host package. Expects MODULE to be set.

# There's not a lot we can do to build reliably in the face of many
|
|
# available configuration options. To be as low-overhead as possible,
|
|
# we follow the following scheme:
|
|
#
|
|
# * Configuration is only re-run when an autoconf source file (such as
|
|
# "configure" or "config.sub") is changed.
|
|
#
|
|
# * "config.status" is run to rebuild Makefiles and .h files if an
|
|
# autoconf-parsed file (such as Makefile.in) is changed.
|
|
#
|
|
# * If MKUPDATE != "no", "make install" is only run if a build has happened
|
|
# since the last install in the current directory.
