Question

如果我尝试make all，我会：

make: ***No rule to make target 'src\SOURCES', needed by 'all'. Stop.

如果我尝试make qwark，我会：

make: ***No rule to make target 'obj\src\SOURCES' needed by 'qwark'. Stop.

如果我尝试make qwark.o，我会

Fatal error: can't create obj\qwark.o: No such file or directory
make: *** [qwark.o] Error 1

这是我的源代码，为了您的观赏乐趣......

COMPILER := g++
CFLAGS := 
LDFLAGS := 
SOURCES := quark.cc
SOURCES := $(addprefix src\,SOURCES)
OBJECTS := $(addprefix obj\,$($(notdir SOURCES):.cc=.o))
EXECUTABLE := qwark.exe
DEBUG := bin\debug\$(EXECUTABLE)
NORMAL := bin\release\$(EXECUTABLE)

all: $(SOURCES) $(EXECUTABLE)

release: qwark
normal: qwark

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

qwark.o: src\qwark.cc
    $(CC) $(CFLAGS) -c src\qwark.cc -o obj\qwark.o

%.o: src\%.cc
    $(CC) $(CFLAGS) -c $(input) -o obj\$(output)

请有人告诉我这是错的..........

Answer 1

您正在修改文字SOURCES字，而不是相应的变量值。请尝试以下方法：

SOURCES := quark.cc

SOURCES := $(addprefix src\,$(SOURCES))
OBJECTS := $(addprefix obj\,$(patsubst %.cc,%.o,$(notdir $(SOURCES))))

或者，更简单：

SOURCES := quark.cc

OBJECTS := $(SOURCES:%.cc=obj\%.o)
SOURCES := $(SOURCES:%=src\%)

Answer 2

在rhs上展开SOURCES变量？

SOURCES := $(addprefix src\,$(SOURCES))
OBJECTS := $(addprefix obj\,$($(notdir $(SOURCES)):.cc=.o))

有makefile相关的噩梦
