Question

我有这个Makefile：

TARGET  =   foobar
CXX     =   g++
CXXFLAGS =  -Wall -I./inc/
LINKER  =   $(CXX) -o
LFLAGS  =   -I./inc/

SRCDIR  =   src
INCDIR  =   inc
OBJDIR  =   obj
BINDIR  =   bin

SOURCES     :=  $(wildcard &(SRCDIR)/*.cpp)
INCLUDES    :=  $(wildcard $(INCDIR)/*.h)
OBJECTS     :=  $(SOURCES:$(SRCDIR)/%.cpp=$(OBJDIR)/%.o)
rm          =   rm -f

$(info SOURCES [${SOURCES}])
$(info INCLUDES [${SOURCES}])
$(info OBJECTS [${OBJECTS}])

$(BINDIR)/$(TARGET): $(OBJECTS)
    @$(LINKER) $@ $(LFLAGS) $(OBJECTS)
    @echo "Linking complete!"

$(OBJECTS): $(OBJDIR)/%.o : $(SRCDIR)/%.cpp
    @$(CXX) $(CXXFLAGS) -c $< -o $@
    @echo "Compiled "$<" successfully"

.PHONY: clean
clean:
    @$(rm) $(OBJECTS)
    @echo "Cleanup complete!"

.PHONE: remove
remove: clean
    @$(rm) $(BINDIR)/$(TARGET) 
    @echo "Exacutable removed!"

我的文件夹结构是：

src/somesources.cpp
inc/somesources.h
obj/
bin/
Makefile

这个makefile与c文件完美配合，但我遇到了c ++问题。有人能说出c和c ++之间的区别以及我错在哪里吗？我得到的输出消息是：

SOURCES []
INCLUDES []
OBJECTS []
g++: fatal error: no input files
compilation terminated.

Answer 1

更改

SOURCES     :=  $(wildcard &(SRCDIR)/*.cpp)

到

SOURCES     :=  $(wildcard $(SRCDIR)/*.cpp)

另外，

.PHONE: remove

应该是

.PHONY: remove

Makefile因c ++编译而失败
