Makefile：對象在編譯和鏈接後不會被刪除

Question

以下makefile的工作原理除了在編譯和鏈接後清理目標文件。我試過make clean，它完全符合我的要求：刪除所有文件夾中的可執行文件和目標文件。我還包括make和make clean的輸出。任何想法？

生成文件：輸出make的

CC=g++ 
CFLAGS=-c -std=c++11 -O2 -O3 
SOURCES=main.cpp\ 
     BoundaryConditions/BoundaryConditions.cpp\ 
     Cell/Cell.cpp\ 
     Face/Face.cpp\ 
     Formulation/Explicit/Explicit.cpp\ 
     Formulation/Implicit/Implicit.cpp\ 
     Grid/Grid.cpp\ 
     Grid/ReadGrid.cpp\ 
     Grid/SetGrid.cpp\ 
     Init/Init.cpp\ 
     InterFlux/Interflux.cpp\ 
     InterFlux/Roe/Roe.cpp\ 
     Matrix5/Operators.cpp\ 
     Output/Output.cpp\ 
     Solver/GaussSeidel.cpp\ 
     Vector/Vector.cpp 
OBJECTS=$(SOURCES:.cpp=.o) 
EXECUTABLE=codeBaku 

all: $(SOURCES) $(EXECUTABLE) 

$(EXECUTABLE): $(OBJECTS) 
    $(CC) $(LDFLAGS) $(OBJECTS) -o $@ 

.cpp.o: 
    $(CC) $(CFLAGS) $< -o $@ 

.PHONY: clean 
clean: 
    rm -rf $(OBJECTS) $(EXECUTABLE) 

：輸出make clean的

g++ -c -std=c++11 -O2 -O3 main.cpp -o main.o

：

rm -rf main.o BoundaryConditions/BoundaryConditions.o Cell/Cell.o Face/Face.o Formulation/Explicit/Explicit.o Formulation/Implicit/Implicit.o Grid/Grid.o Grid/ReadGrid.o Grid/SetGrid.o Init/Init.o InterFlux/Interflux.o InterFlux/Roe/Roe.o Matrix5/Operators.o Output/Output.o Solver/GaussSeidel.o Vector/Vector.o codeBaku

自動刪除目標文件是很常見的，因爲這意味着每次都需要重新編譯所有內容，即使只更改一個源文件也是如此。但是，如果你真的想這樣做，你可以做這樣的事情：

all: $(SOURCES) $(EXECUTABLE) 
     rm $(OBJECTS)
