By convention, each package has two package names. In this text we will refer to them as $pkg and $PKG. The name $pkg usually consists of lower case letters, digits, underlines and hyphens. $PKG consists of uppercase letters, digits and underlines, but no hyphens. Normally $PKG is the name $pkg with letters converted to upper case and hyphens converted to underlines. Version numbers are not part of a package name, so most package names don't contain digits. Packages may be either library packages or binary packages. Library packages are in make/libs/*, while binary packages are in make/*. Each package must define the following targets: ${pkg}-source Download source for the package ${pkg}-precompiled Compile package and prepare for firmware generation or ${pkg}-package ${pkg}-package Create a precompiled binary package ${pkg}-clean ${pkg}-dirclean Remove all files that can be recreated ${pkg}-list add package to the list of static or dynamic patches To use the convenience macros, you need some more defines: # initialize package macros, ether BINary or LIBrary. # $(1) = version (mandatory) # $(2) = lower-case package name (optional, default name of makefile) # $(3) = upper-case package name (optional, default $2 converted to uppercase/underline) # default values for # - $(PKG)_DIR : directory for sources # - $(PKG)_MAKE_DIR : directory for freetz makefile, patches and files # - $(PKG)_TARGET_DIR : directory for installation BIN: $(call PKG_INIT_BIN, VERSION, [pkg], [PKG]) LIB: $(call PKG_INIT_LIB, VERSION, [pkg], [PKG]) # The download URL, split in directory part and filename $(PKG)_SITE:=http://www.server.net/download $(PKG)_SOURCE:=package-name-$($(PKG)_VERSION).tar.gz # directory containing the makefiles. This value is the default from PKG_INIT. # It should not be necessary to override this value. $(PKG)_MAKE_DIR:=$(MAKE_DIR)/$(pkg) # directory for sourcefile, "$(SOURCE_DIR)/" and the directory created by extracting the tar-file # This value is the default from PKG_INIT. $(PKG)_DIR:=$(SOURCE_DIR)/package-name-$($(PKG)_VERSION) # target directory for the package. The default value depends on BIN/LIB, # It should not be necessary to override this value.
