用于cppunit的makefile

Question

这是我的makefile

#Makefile
CC=g++
CFLAGS=-lcppunit
OBJS=Money.o MoneyTest.o

all : $(OBJS)
    $(CC) $(OBJS) -o TestUnitaire

#création des objets 
Money.o: Money.cpp Money.hpp
    $(CC) -c Money.cpp $(CFLAGS)

MoneyTest.o: MoneyTest.cpp Money.hpp MoneyTest.hpp
    $(CC) -c MoneyTest.cpp $(CFLAGS)

clean:
    rm *.o $(EXEC)

当我运行这个makefile时，会得到这样的错误：

O MoneyTest.o main': Money.cpp:(.text+0x3c): undefined reference toCppUnit::TestFactoryRegistry::getRegistry(std::basic_string，-o TestUnitaire Money.o:在函数g++ std::allocator > const&)‘Money.cpp:(.text+0x78)：未定义引用CppUnit::TextTestRunner::TextTestRunner(CppUnit::Outputter*)' Money.cpp:(.text+0x8c): undefined reference toCppUnit::TestRunner::addTest(CppUnit::Test*)’Money.cpp:(.text+0x98)：未定义的对CppUnit::TextTestRunner::result() const' Money.cpp:(.text+0xec): undefined reference toCppUnit::CompilerOutputter::CompilerOutputter(CppUnit::TestResultCollector*，std::basic_ostream >& std::basic_string，CppUnit::TextTestRunner::setOutputter(CppUnit::Outputter*)' Money.cpp:(.text+0x168): undefined reference toCppUnit::TextTestRunner::run(std::basic_string，：：分配器> const&)‘Money.cpp:(.text+0xfc)：未定义的对CppUnit::TextTestRunner::~TextTestRunner()' Money.cpp:(.text+0x233): undefined reference toCppUnit::TextTestRunner::~TextTestRunner()’的引用：：分配程序>，bool，bool，bool)‘Money.cpp:(.text+0x1a5)：未定义的对CppUnit::TextTestRunner::~TextTestRunner()' Money.cpp:(.text+0x233): undefined reference toCppUnit：：TextTestRunner：：~TextTestRunner()’的引用

似乎我们班之间没有任何联系。有什么问题吗？

-lcppunit标志在CFLAGS中是不正确的，这是放置C编译器标志的地方。您是(a)编译C++程序，而不是C程序，和(b) -l标志是链接器标志，而不是编译器标志。此外，CC变量包含C编译器。您应该将CXX变量用于C++编译器。生成文件应该如下所示：

#Makefile
CXX = g++
LDLIBS = -lcppunit
OBJS = Money.o MoneyTest.o

all : TestUnitaire

TestUnitaire: $(OBJS)
        $(CXX) $^ -o $@ $(LDFLAGS) $(LDLIBS)

#création des objets
%.o : %.cpp
        $(CXX) $(CPPFLAGS) $(CXXFLAGS) -o $@ -c $<

Money.o: Money.hpp
MoneyTest.o: Money.hpp MoneyTest.hpp

clean:
        rm *.o $(EXEC)
