c++ - Makefile - 通配符，如何正确执行？

Question

FLAGS:= -Wall -Wvla -g -lm
OBJECT := Nominated.h UniversityNominated.h AliceGraduate.h BobGraduate.h CollegeNominated.h ColinGraduate.h DannyGraduate.h NominatedList.h Parser.h Parser.cpp
all: Hire

Nominated.o: Nominated.h Nominated.cpp
    g++ -c $(FLAGS) Nominated.cpp -o Nominated.o

NominatedList.o: Nominated.h NominatedList.h NominatedList.cpp
    g++ -c $(FLAGS) NominatedList.cpp -o NominatedList.o

UniversityNominated.o: Nominated.h UniversityNominated.h UniversityNominated.cpp
    g++ -c $(FLAGS) UniversityNominated.cpp -o UniversityNominated.o

AliceGraduate.o: Nominated.h UniversityNominated.h AliceGraduate.h AliceGraduate.cpp
    g++ -c $(FLAGS) AliceGraduate.cpp -o AliceGraduate.o

BobGraduate.o: Nominated.h UniversityNominated.h BobGraduate.h BobGraduate.cpp
    g++ -c $(FLAGS) BobGraduate.cpp -o BobGraduate.o

CollegeNominated.o: Nominated.h CollegeNominated.h CollegeNominated.cpp
    g++ -c $(FLAGS) CollegeNominated.cpp -o CollegeNominated.o

ColinGraduate.o: Nominated.h CollegeNominated.h ColinGraduate.h ColinGraduate.cpp
    g++ -c $(FLAGS) ColinGraduate.cpp -o ColinGraduate.o

DannyGraduate.o: Nominated.h CollegeNominated.h DannyGraduate.h DannyGraduate.cpp
    g++ -c $(FLAGS) DannyGraduate.cpp -o DannyGraduate.o

Parser.o: $(OBJECT)  
    g++ -c $(FLAGS) Parser.cpp -o Parser.o

Parser: Nominated.o UniversityNominated.o AliceGraduate.o BobGraduate.o CollegeNominated.o ColinGraduate.o DannyGraduate.o NominatedList.o Parser.o
    ar rcu libParser.a Nominated.o UniversityNominated.o AliceGraduate.o BobGraduate.o CollegeNominated.o ColinGraduate.o DannyGraduate.o NominatedList.o Parser.o
    ranlib libParser.a

Hire: Hire.cpp Parser
    g++ Hire.cpp libParser.a -o Hire

clean:
    rm -f Hire *.a *.o *~
.PHONY: clean all

所以这是我的 Makefile。

我怎样才能不那么丑陋？

我总是读到它，但我无法理解

如何？

我的意思是我知道我需要使用通配符工具，但正如您所说，我可能用错了

Answer 1

这是一个如何使用通配符和模式替换的示例:

SOURCES := $(wildcard *.cpp)
OBJECTS := $(patsubst %.cpp,%.o,$(SOURCES))
CXX := g++ -Wall -Wvla -g

.cpp.o:
        ${CXX} -c $<

这会将所有 .cpp 文件构建到它们的目标文件中。
