The Makefile begins on line 6 to 8 with metadata information: the
+GENTARGETS+ Reference
~~~~~~~~~~~~~~~~~~~~~~
-The +GENTARGETS+ macro takes three arguments:
-
-* The first argument is the package directory prefix. If your package
- is in +package/libfoo+, then the directory prefix is +package+. If
- your package is in +package/editors/foo+, then the directory prefix
- must be +package/editors+.
-
-* The second argument is the lower-cased package name. It must match
- the prefix of the variables in the +.mk+ file and must match the
- configuration option name in the +Config.in+ file. For example, if
- the package name is +libfoo+, then the variables in the +.mk+ file
- must start with +LIBFOO_+ and the configuration option in the
- +Config.in+ file must be +BR2_PACKAGE_LIBFOO+.
-
-* The third argument is optional. It can be used to tell if the
- package is a target package (cross-compiled for the target) or a
- host package (natively compiled for the host). If unspecified, it is
- assumed that it is a target package. See below for details.
+The +GENTARGETS+ macro takes one optional argument. This argument can
+be used to tell if the package is a target package (cross-compiled for
+the target) or a host package (natively compiled for the host). If
+unspecified, it is assumed that it is a target package. See below for
+details.
For a given package, in a single +.mk+ file, it is possible to call
GENTARGETS twice, once to create the rules to generate a target
package and once to create the rules to generate a host package:
----------------------
-$(eval $(call GENTARGETS,package,libfoo))
-$(eval $(call GENTARGETS,package,libfoo,host))
+$(eval $(call GENTARGETS))
+$(eval $(call GENTARGETS,host))

This might be useful if the compilation of the target package requires
