Question

以下makefile工作，但在编译和链接后清除目标文件除外。我尝试了make clean，它完全符合我的要求：删除所有文件夹中的可执行文件和目标文件。我还包括make和make clean的输出。有什么想法吗？

生成文件：

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)

make的输出：

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

g++ -c -std=c++11 -O2 -O3 Matrix5/Operators.cpp -o Matrix5/Operators.o
g++ -c -std=c++11 -O2 -O3 Output/Output.cpp -o Output/Output.o
g++ -c -std=c++11 -O2 -O3 Solver/GaussSeidel.cpp -o Solver/GaussSeidel.o
g++ -c -std=c++11 -O2 -O3 Vector/Vector.cpp -o Vector/Vector.o
g++  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 -o codeBaku

make clean的输出：

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

自动删除目标文件是不常见的，因为这意味着每次都必须重新编译所有内容，即使您只更改了一个源文件。但是，如果你真的想这样做，你可以这样做：

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

Makefile：编译和链接后不删除对象
