Infrastructure for host packages
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[[host-package-tutorial]]

First, let's see how to write a +Makefile+ for an host only package, required
by another target package to build, with an example:

------------------------
01: # This file is part of the OpenADK project. OpenADK is copyrighted
02: # material, please see the LICENCE file in the top-level directory.
03:
04: include $(ADK_TOPDIR)/rules.mk
05:
06: PKG_NAME:=              hostfoo
07: PKG_VERSION:=           1.0
08: PKG_RELEASE:=           1
09: PKG_MD5SUM:=            291ba57c0acd218da0b0916c280dcbae
10: PKG_DESCR:=             hostfoo utility
11: PKG_SECTION:=           misc
12: PKG_URL:=               http://www.foo.org/
13: PKG_SITES:=             http://download.foo.org/
14:
15: PKG_CFLINE_HOSTFOO:=    depends on ADK_HOST_ONLY
16:
17: include $(ADK_TOPDIR)/mk/host.mk
18: include $(ADK_TOPDIR)/mk/package.mk
19:
20: $(eval $(call HOST_template,HOSTFOO,hostfoo,$(PKG_VERSION)-${PKG_RELEASE}))
21:
22: HOST_STYLE:=            auto
23:
24: include ${ADK_TOPDIR}/mk/host-bottom.mk
25: include ${ADK_TOPDIR}/mk/pkg-bottom.mk
------------------------

The differences to a target package is the inclusion of +mk/host.mk+ in line 17 and
+mk/host-bottom.mk+ in line 24. Furthermore the HOST_template is called instead of
the PKG_template. The last difference is the usage of +PKG_CFLINE_HOSTFOO+ to mark
the package as host only package.

Following mix between host and target package is possible, too:
------------------------
01: # This file is part of the OpenADK project. OpenADK is copyrighted
02: # material, please see the LICENCE file in the top-level directory.
03:
04: include ${ADK_TOPDIR}/rules.mk
05:
06: PKG_NAME:=		foo
07: PKG_VERSION:=	1.0
08: PKG_RELEASE:=	1
09: PKG_MD5SUM:=	032a7b7b9f1a6e278ccde73f82cec5c2
10: PKG_DESCR:=		foo tool
11: PKG_SECTION:=	lang
12: PKG_BUILDDEP:=	foo-host
13: PKG_URL:=		http://www.foo.org/
14: PKG_SITES:=		http://download.foo.org/
15:
16: include ${ADK_TOPDIR}/mk/host.mk
17: include ${ADK_TOPDIR}/mk/package.mk
18:
19: $(eval $(call HOST_template,FOO,foo,${PKG_VERSION}-${PKG_RELEASE}))
20: $(eval $(call PKG_template,FOO,foo,${PKG_VERSION}-${PKG_RELEASE},${PKG_DEPENDS},${PKG_DESCR},${PKG_SECTION}))
21:
22: HOST_STYLE:=	auto
23:
24: foo-install:
25:	${INSTALL_DIR} ${IDIR_FOO}/usr/bin
26:	${INSTALL_BIN} ${WRKINST}/usr/bin/foo ${IDIR_FOO}/usr/bin
27:
28: include ${ADK_TOPDIR}/mk/host-bottom.mk
29: include ${ADK_TOPDIR}/mk/pkg-bottom.mk
------------------------

If you need to rebuild a mixed package, you can do:
------------
 $ make package=<package> hostclean hostpackage clean package
------------

If your host package have some dependencies, use following:
------------
 HOST_BUILDDEP:=libbaz-host bar-host
------------
