[SOLVED] Makefile targets autocomplete when using wild card targets

Issue

> ls
abcd.config  efgh.config  ijkl.config

Makefile:

%_defconfig: %.config
    @echo "Some commands i want to run on %.config"

What i want is autosuggestion (tab completion) for

abcd_defconfig 
efgh_defconfig
ijkl_defconfig 

Solution

Explicitly declare the targets for which you want auto completion? For instance with the wildcard and patsubst functions and a static pattern rule instead of a pattern rule:

configs     := $(wildcard *.config)
defconfigs  := $(patsubst %.config,%_defconfig,$(configs))

$(defconfigs): %_defconfig: %.config
    @echo "Some commands i want to run on $<"
