Cppunit; trying to compile class to test

Question

I am quite new to both C++ and Cppunit. I am trying to compile a little cppunit test. However, I do not succeed.

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

This is the sourcecode. What am I missing here?

    mY = y;

Answer 1

Add coordinate.cpp to your command-line. The linker can't find the bodies of any of the Coordinate::* methods.

Answer 2

Try adding Coordinate.cpp to your commandline.

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
