Percent symbol not getting evaluated in makefile -

i'm new makefiles etc.

the file looks this:

compiler_name = gcc compiler_flags =  path_objects = ./obj path_sources = ./src  $(path_objects)/%.o: $(path_sources)/%.c     $(info generating object files...)     @$(compiler_name) $(compiler_flags) -c $< -o $@  cleanup: $(path_objects)/%.o     $(info final cleanup...)     @rm -rf $< 

when try make project error: make: *** no rule make target 'obj/%.o', needed 'cleanup'. stop.

it's % wildcard not getting evaluated correctly. please me.

a pattern rule has '%' in target, , maybe in 1 or more of prerequisites. have:

cleanup: $(path_objects)/%.o     ... 

is not pattern rule, , '%' not wildcard, it's character. that's ordinary rule looks file called "./obj/%" prerequisite, , there's no such file.

if want cleanup remove of object files in directory, there's no need of complication. this:

cleanup:     @echo final cleanup...     @rm -rf $(path_objects)/*.o 

note uses shell command echo, not make command info, , shell wildcard '*', not make wildcard '%'.

if want target depend on object files can build, must construct list yourself; it's not difficult, doesn't need here.
