MakeFile目標目錄

Question

我有我的代碼在src文件夾中。 src/Client包含用於創建客戶端應用程序的makefile。 src/Server包含一個用於創建客戶端應用程序的makefile。 我在與src相同的文件夾中有一個bin文件。 名爲ad的文件夾包含src和bin。 在箱櫃中，我有一個makefile

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

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

我的問題是，我想在所有箱子我的可執行文件，但是現在他們在服務器和客戶端文件夾中創建。

我的makefile在客戶端文件夾：

# 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) 

我應該在這個文件改變什麼？

Answer 1

通常，您的主makefile是構建可執行文件的內容。輔助應該創建目標文件。在這種情況下，將實際的正義之舉的可執行文件的根文件夾：

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

如果你真的想這樣做是正確的，目標文件從主化妝

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

連結，並在輔助文件只是編譯

# 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

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) 

這工作
