One last Make question (for now!) ****************** IN BRIEF: I'm having difficulty with the ".cpp.obj" style syntax for automatically creating any required .obj file from its corresponding .cpp file.
I'm trying to change this: $(FULL_LIST_OF_OBJECT_FILES_WITH_PATHS) : $(OUTPUT_PATH)/%.obj: %.cpp #works to something like this: {}.cpp{$(OUTPUT_PATH)}.obj: #doesn't work So I'm hoping somebody can please help me with the syntax...! ****************** IN DETAIL: I'm building a set of object files in a subdirectory from a set of .cpp files in the current directory. I've got it working fine by explicitly listing the object files: ##################################### # this works a treat: OUTPUT_PATH = ./Subfolder TARGET_EXE = ./Subfolder/Foo.exe FULL_OBJ_LIST = ./Subfolder/Foo.obj\ ./Subfolder/Bar.obj\ ./Subfolder/Another.obj # ... # link step $(TARGET_EXE) : $(FULL_OBJ_LIST) link /OUT:$(TARGET_EXE) $(FULL_OBJ_LIST) # compile step $(FULL_OBJ_LIST) : $(OUTPUT_PATH)/%.obj: %.cpp $(CC) $(SWITCHES) $*.cpp ##################################### This works absolutely fine. (Took me ages to get to this stage!) ;) Now I've been experimenting with implicit/inference rules (not quite sure of the terminology? -- the .cpp.obj style syntax) to achieve the same thing without having to refer to FULL_OBJ_LIST in the compile step ... but without any luck. :( Here are my best attempts: ##################################### # ATTEMPT A: ##################################### # alternative compile step {}.cpp{$(OUTPUT_PATH)}.obj: $(CC) $(SWITCHES) $*.cpp # error: # target `{}.cpp{./Subfolder}.obj' doesn't match the target pattern ##################################### ##################################### # ATTEMPT B: ##################################### # alternative compile step {}.cpp{$(OUTPUT_PATH)}.obj: $(OUTPUT_PATH)/%.obj: $(CC) $(SWITCHES) $*.cpp # error: # No rule to make target `Subfolder/Foo.obj', needed by `Subfolder/Foo.exe'. ##################################### Any idea what I'm doing wrong?
