所以我有兩個並排的遊戲。鏈接/集成問題。我需要一個方向去哪裏？
proj2/main.cpp (main that gets run that then can call either game)
proj2/spades/display.cpp
proj2/spades/gameplay.cpp
proj2/spades/otherFiles.cpp
proj2/hearts/display.cpp (this is the same display class as in the spades game with the same functions just sightly altered.)
proj2/hearts/hearts.cpp
proj2/hearts/otherFiles.cpp
基本上什麼事情是我試圖整合2場，1我創建，另一個使用相同display.cpp和display.h文件稍有改變。爲了做到這一點，我創建了2個獨立的命名空間，心臟和黑桃。我編譯的所有東西都很好，但一些.cpp文件沒有正確鏈接，並且出現如下錯誤。
./gamePlay.o: In function `__static_initialization_and_destruction_0(int, int)':
gamePlay.cpp:(.text+0x396): undefined reference to `spades::display::display()'
./gamePlay.o: In function `__tcf_3':
gamePlay.cpp:(.text+0x480): undefined reference to `spades::display::~display()'
./gamePlay.o: In function `spades::gamePlay::storeBid(std::basic_stringstream<char, std::char_traits<char>, std::allocator<char> >&)':
gamePlay.cpp:(.text+0x1507): undefined reference to `spades::display::captureInput()'
我在這裏做錯了什麼？
下面是一些我使用的文件。讓我知道，如果有任何我應該補充。 （不想臃腫這個帖子了，比我有）
