1 # sourceipk.bbclass enables the creation of an ipk file that contains the
2 # sources used during the build. The sources contained in the ipk are the
3 # patched sources before configuration has been done.
5 # This class is used to provide an easy method to ship the corresponding
6 # sources for a package to end users so that they can install them on their
7 # host or target systems.
9 # This package uses the following variables to control its operations:
10 # - CREATE_SRCIPK = When set to 1 this variable indicates that
11 # a source ipk should be generated for the package.
12 # - SRCIPK_INSTALL_DIR = This variable indicates the directory to install
14 # - SRCIPK_PACKAGE_ARCH = This variable allows specific recipies to
15 # specify an architecture for the sourcetree
16 # package is "all" is not appropriate
17 # - SRCIPK_INC_EXTRAFILES = When set to 1 this variable indicates that
18 # the source ipk should contain extra files
19 # such as the README file and recipe.
21 # The default installation directory for the sources is:
24 # By setting the SRCIPK_INSTALL_DIR this default can be changed to any
25 # location desired. When combined with the opkg -o option this allows for the
26 # system building to specify a relative package install location to the
27 # install root given to opkg. Each source ipk can have a different directory.
29 # Creation of the source ipk can be controlled per package by setting
30 # CREATE_SRCIPK = "1" in the package recipe or by setting
31 # CREATE_SRCIPK_pn-<package name> = "1" in your local.conf
34 # Need to figure out how to use opkg-build in this class.
35 # I tried adding it as a dependency for the do_create_srcipk
37 # do_create_srcipk[depends] += "opkg-utils-native:do_populate_sysroot"
38 # But then there is a circular dependency between sourcipk.bbclass and
39 # opkg-utils-native. Until I can figure out how to resolve this
40 # circular dependency I am extracting the needed pieces from opkg-build
41 # into this class and building the source ipk myself.

47 # Default installation prefix
48 SRCIPK_INSTALL_DIR ?= "/usr/src/${PN}-src"
