Question

我对C ++和Cppunit都很陌生。我正在尝试编译一个小的cppunit测试。但是，我没有成功。

qwerty@qwerty:~/chessgame/src$ g++ -Wall CoordinateTest.cpp ftest.cpp -lcppunit -o test
/tmp/cc1vJJqz.o: In function `CoordinateTest::coordinateTest()':
CoordinateTest.cpp:(.text+0xbb): undefined reference to `Coordinate::Coordinate(int const&, int const&)'
CoordinateTest.cpp:(.text+0xe2): undefined reference to `Coordinate::Coordinate(int const&, int const&)'
collect2: ld returned 1 exit status

这是源代码。我在这里错过了什么？

Answer 1

尝试将Coordinate.cpp添加到命令行。

qwerty @ qwerty：〜/ chessgame / src $ g ++ -Wall CoordinateTest.cpp ftest.cpp -lcppunit -o test

qwerty @ qwerty：〜/ chessgame / src $ g ++ -Wall CoordinateTest.cpp Coordinate.cpp ftest.cpp -lcppunit -o test

Answer 2

将coordinate.cpp添加到命令行。链接器无法找到任何Coordinate::*方法的主体。

CppUnit的;试图编译类进行测试
