Question

我的代码在src文件夹中。 src / Client包含用于创建客户端应用程序的makefile。 src / Server包含用于创建客户端应用程序的makefile。我在与src相同的文件夹中有一个bin文件。名为ad的文件夹包含src和bin。在bin我有一个makefile

all: 
    cd ../src/Server; make
    cd ../src/Client; make

clean: 
    cd ../src/Server; make clean
    cd ../src/Client; make clean

我的问题是我想要bin中的所有可执行文件，但现在它们是在Server and Client文件夹中创建的。

我在客户端文件夹中的makefile：

# Define the compiler and the linker. The linker must be defined since
# the implicit rule for linking uses CC as the linker. g++ can be
# changed to clang++.
CXX = g++
CC  = g++

# Define preprocessor, compiler, and linker flags. Uncomment the # lines
# if you use clang++ and wish to use libc++ instead of libstd++.
CPPFLAGS  =-I.. -I ../database

CXXFLAGS =  -g -O2 -Wall -W -pedantic-errors
CXXFLAGS += -Wmissing-braces -Wparentheses -Wold-style-cast 
CXXFLAGS += -std=c++11 
LDFLAGS =   -g -L.. -L../database
#CPPFLAGS += -stdlib=libc++
#CXXFLAGS += -stdlib=libc++
#LDFLAGS +=  -stdlib=libc++

# Libraries
LDLIBS = -lclientserver -ldatabase

# Targets
PROGS = interface


all: $(PROGS)

# Targets rely on implicit rules for compiling and linking
# The dependency on libclientserver.a is not defined.
interface: interface.o com.o ans.o

# Phony targets
.PHONY: all clean

# Standard clean
clean:
    rm -f *.o $(PROGS)

# Generate dependencies in *.d files
%.d: %.cc
    @set -e; rm -f $@; \
         $(CPP) -MM $(CPPFLAGS) $< > $@.$$$$; \
         sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
         rm -f $@.$$$$

# Include the *.d files
SRC = $(wildcard *.cc)
include $(SRC:.cc=.d)

我应该在此档案中更改什么？

Answer 1

通常，您的主makefile是构建可执行文件的内容。辅助的应该是制作目标文件。在这种情况下，将可执行文件移动到根文件夹是可行的：

mv src/Client/$(EXECUTABLE) src/bin
mv src/Server/$(EXECUTABLE) src/bin

如果您确实想要做到正确，请链接主要生成

中的目标文件

all:
      $(CC) $(LDFLAGS) $(CLIENT_FOLDER)/*.o $(SERVER_FOLDER)/*.o $(BIN_FOLDER)/$(EXECUTABLE)

使aux文件只需编译

# Define the compiler and the linker. The linker must be defined since
# the implicit rule for linking uses CC as the linker. g++ can be
# changed to clang++.
CXX = g++
CC  = g++

# Define preprocessor, compiler, and linker flags. Uncomment the # lines
# if you use clang++ and wish to use libc++ instead of libstd++.
CPPFLAGS  =-I.. -I ../database

CXXFLAGS =  -g -O2 -Wall -W -pedantic-errors
CXXFLAGS += -Wmissing-braces -Wparentheses -Wold-style-cast 
CXXFLAGS += -std=c++11 
LDFLAGS =   -g -L.. -L../database
#CPPFLAGS += -stdlib=libc++
#CXXFLAGS += -stdlib=libc++
#LDFLAGS +=  -stdlib=libc++

# Libraries
LDLIBS = -lclientserver -ldatabase

# Targets
PROGS = interface


all: $(PROGS)

# Targets rely on implicit rules for compiling and linking
# The dependency on libclientserver.a is not defined.
interface: interface.o com.o ans.o
     $(CXX) -o ../../bin/$@ $^ $(LDLIBS) $(LDFLAGS)
# Phony targets
.PHONY: all clean

# Standard clean
clean:
    rm -f *.o $(PROGS)

# Generate dependencies in *.d files
%.d: %.cc
    @set -e; rm -f $@; \
         $(CPP) -MM $(CPPFLAGS) $< > $@.$$$$; \
         sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
         rm -f $@.$$$$

# Include the *.d files
SRC = $(wildcard *.cc)
include $(SRC:.cc=.d)

这有效

MakeFile目标目录
