我正在尝试使用以下make文件编译我的程序。我在互联网上找到了一个模板,我正在尝试使用它。我只修改了# Main entry point
制作文件
# Define executable name
BIN = CLI_DeskManager
# Define source files
SRCS = main.cpp shell.cpp
# Define header file paths
INCPATH = -I./ -I/usr/include/X11/exensions -I/usr/include/X11 -I/home/julien/Documents/DeskManagerDll
# Define the -L library path(s)
LDFLAGS = -L/usr/X11R6/lib -L/home/julien/Documents/DeskManagerDll
# Define the -l library name(s)
LIBS = -lX11 -lXext -Wl,--no-as-needed -lDeskManager -lpthread
# Only in special cases should anything be edited below this line
OBJS = $(CPP_SRCS:.cpp=.o)
CXXFLAGS = -Wall -ansi -pedantic -std=c++11 -pthread
DEP_FILE = .depend
# Main entry point
#
all: depend $(BIN)
# For linking object file(s) to produce the executable
#
$(BIN): $(OBJS)
@echo Linking $@
@$(CXX) $^ $(LDFLAGS) $(LIBS) -o $@
# For compiling source file(s)
#
.cpp.o:
@echo Compiling $<
@$(CXX) -c $(CXXFLAGS) $(INCPATH) $<
# For cleaning up the project
#
clean:
$(RM) $(OBJS)
distclean: clean
$(RM) $(BIN)
$(RM) $(DEP_FILE)
# For determining source file dependencies
#
depend: $(DEP_FILE)
@touch $(DEP_FILE)
$(DEP_FILE):
@echo Generating dependencies in $@
@-$(CXX) -E -MM $(CXXFLAGS) $(INCPATH) $(SRCS) >> $(DEP_FILE)
ifeq (,$(findstring clean,$(MAKECMDGOALS)))
ifeq (,$(findstring distclean,$(MAKECMDGOALS)))
-include $(DEP_FILE)
endif
endif
错误
但我有很多错误,如下面的
/usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
但是on this thread soru说重要的是:
(.text+0x18): undefined reference to `main'
collect2: error: ld returned 1 exit status
make: *** [CLI_DeskManager] Error 1
其他信息
我已经使用Code :: blocks成功编译了它,这是构建日志。
g++ -Wall -fexceptions -std=c++11 -g -pthread -I/usr/include/X11/extensions -I/usr/include/X11 -I../DeskManagerDll -c /home/julien/Documents/CommandLineInterface_DeskManager/main.cpp -o obj/Debug/main.o
g++ -Wall -fexceptions -std=c++11 -g -pthread -I/usr/include/X11/extensions -I/usr/include/X11 -I../DeskManagerDll -c /home/julien/Documents/CommandLineInterface_DeskManager/shell.cpp -o obj/Debug/shell.o

我在StackOverflow上找到了答案,但我不理解它们。
我做错了什么?
谢谢。
更新
推荐修改后的Makefile
# Define executable name
BIN = CLI_DeskManager
# Define source files
SRCS = main.cpp shell.cpp
# Define header file paths
INCPATH = -I./ -I/usr/include/X11/exensions -I/usr/include/X11 -I/home/julien/Documents/DeskManagerDll
# Define the -L library path(s)
LDFLAGS = -L/usr/X11R6/lib -L/home/julien/Documents/DeskManagerDll/bin/Debug
# Define the -l library name(s)
LIBS = -lX11 -lXext -Wl,--no-as-needed -lDeskManagerDll -lpthread
# Only in special cases should anything be edited below this line
OBJS = $(CPP_SRCS:.cpp=.o)
CXXFLAGS = -Wall -ansi -pedantic -std=c++11 -pthread
DEP_FILE = .depend
# Main entry point
#
all: depend $(BIN)
# For linking object file(s) to produce the executable
#
$(BIN): $(OBJS)
echo Linking $@
$(CXX) $^ $(LDFLAGS) $(LIBS) -o $@
# For compiling source file(s)
#
.cpp.o:
echo Compiling $<
$(CXX) -c $(CXXFLAGS) $(INCPATH) $< -o $@
# For cleaning up the project
#
clean:
$(RM) $(OBJS)
distclean: clean
$(RM) $(BIN)
$(RM) $(DEP_FILE)
# For determining source file dependencies
#
depend: $(DEP_FILE)
touch $(DEP_FILE)
$(DEP_FILE):
echo Generating dependencies in $@
-$(CXX) -E -MM $(CXXFLAGS) $(INCPATH) $(SRCS) >> $(DEP_FILE)
ifeq (,$(findstring clean,$(MAKECMDGOALS)))
ifeq (,$(findstring distclean,$(MAKECMDGOALS)))
-include $(DEP_FILE)
endif
endif
完全输出。我很抱歉这是法语。我的问题的第一部分只翻译了两个不同的句子。

答案 0 :(得分:2)
稍微不清楚您要实现的目标是什么,您是尝试创建共享库还是只是尝试使用它?
Code ::阻止第二个选项的日志提示,如果是这种情况,我注意到你在code :: blocks log中有libDeskManagerDll.so,在makefile中有-lDeskManager,因为它们是相同的我会预计将成为-lDeskManagerDll
这条线对我来说也很奇怪
@$(CXX) -c $(CXXFLAGS) $(INCPATH) $<
我本以为它看起来像
@$(CXX) -c $(CXXFLAGS) $(INCPATH) $< -o $@
如果这不能解决问题,你可以删除makefile中行开头的@符号并发布make的完整输出吗?
<强>更新强>
从您的更新中可以清楚地看到make不包含链接命令中的目标文件。仔细检查线
SRCS = main.cpp shell.cpp
定义您尝试与
一起使用的源文件OBJS = $(CPP_SRCS:.cpp=.o)
将该行更改为
OBJS = $(SRCS:.cpp=.o)
应该让你更接近你想要的东西
