C++ “没有可用的来源”；main（）；c+的错误+；日蚀

我知道以前有很多人问过这个问题，但我一直没能解决。我想在eclipse中调试makefile项目，但我不能。我刚学C++，不知道怎么写Mag文件，但是我的老师给我一个用，我已经把它贴在下面了。如何修复此错误

另外，如果这对你们有帮助的话，我只想调试DijkstraTest.cpp主函数，而不是其他任何函数

# first name a variable objects for all object files
# FOR strauss
#CXX = CC

objectsqueue = LinkedList.o

objectstestqueue = QueueTests.o

objectsheap = BinaryHeap.o

objectstestheap = BinaryHeapTest.o

objectsdijkstra = CSV.o Network.o Dijkstra.o

objectstestdijkstra = DijkstraTest.o

# name a variable sources for all source files

sourcesqueue = LinkedList.cpp

sourcestestqueue = QueueTests.cpp

sourcesheap = BinaryHeap.cpp

sourcestestheap = BinaryHeapTest.cpp

sourcesdijkstra = CSV.cpp Network.cpp Dijkstra.cpp

sourcestestdijkstra = DijkstraTest.cpp

# now make default target all exe files
all: testqueue testheap testdijkstra

# list the dependencies for object files - those header files which help build objects
LinkedList.cpp: Collection.h Stack.h Queue.h
QueueTests.o: QueueTests.cpp LinkedList.cpp
BinaryHeap.o: BinaryHeap.h 
BinaryHeapTest.o: BinaryHeap.h 
Dijkstra.o: CSV.h Dijkstra.h Network.h BinaryHeap.h 

# how to build all object files from all dependent source files

$(objectsqueue): $(sourcesqueue)
$(CXX) -c $(sourcesqueue) $(INCLUDES)

$(objectstestqueue): $(sourcestestqueue)
$(CXX) -c $(sourcestestqueue) $(INCLUDES)

$(objectsheap): $(sourcesheap)
$(CXX) -c $(sourcesheap) $(INCLUDES)

$(objectstestheap): $(sourcestestheap)
$(CXX) -c $(sourcestestheap) $(INCLUDES)

$(objectsdijkstra): $(sourcesdijkstra)
$(CXX) -c $(sourcesdijkstra) $(INCLUDES)

$(objectstestdijkstra): $(sourcestestdijkstra)
$(CXX) -c $(sourcestestdijkstra) $(INCLUDES)

clean:
rm -f *.o
rm -f *.exe

testqueue:  $(objectsqueue) $(objectstestqueue)
$(CXX) -o QueueTests.exe $(objectsqueue) $(objectstestqueue)

testheap: $(objectsheap) $(objectstestheap) 
$(CXX) -o BinaryHeapTest.exe $(objectsheap) $(objectstestheap)

testdijkstra: $(objectsheap) $(objectsdijkstra) $(objectstestdijkstra) 
$(CXX) -o DijkstraTest.exe $(objectsheap) $(objectsdijkstra) $(objectstestdijkstra)

为了能够调试应用程序，您需要使用

-g

（调试）标志对其进行编译：

---

所有编译规则都需要使用此标志。

代码中是否有main（）？是的，我的每个test.cpp文件中都有一个。应该只有1个

main

函数。您是否在编译器或链接器的命令行中包含了

test.cpp

文件？不，我不知道该怎么做。我已经删除了另外两个带有主要函数的测试文件，但是没有什么区别

CXXFLAGS=-g

$(objectsqueue): $(sourcesqueue)
$(CXX) $(CXXFLAGS) -c $(sourcesqueue) $(INCLUDES)

...

testqueue:  $(objectsqueue) $(objectstestqueue)
$(CXX) $(CXXFLAGS) -o QueueTests.exe $(objectsqueue) $(objectstestqueue)

....
