5.4 When userspace programs are actually built
----------------------------------------------
- Same as "When host programs are actually built".
+ Kbuild builds userspace programs only when told to do so.
+ There are two ways to do this.
+
+ (1) Add it as the prerequisite of another file
+
+ Example::
+
+ #net/bpfilter/Makefile
+ userprogs := bpfilter_umh
+ $(obj)/bpfilter_umh_blob.o: $(obj)/bpfilter_umh
+
+ $(obj)/bpfilter_umh is built before $(obj)/bpfilter_umh_blob.o
+
+ (2) Use always-y
+
+ Example::
+
+ userprogs := binderfs_example
+ always-y := $(userprogs)
+
+ Kbuild provides the following shorthand for this:
+
+ userprogs-always-y := binderfs_example
+
+ This will tell Kbuild to build binderfs_example when it visits this
+ Makefile.
