錯誤在ROS中使用yaml-cpp？

Question

我正在嘗試使用yaml-cpp，並且根據wiki，這是一個系統依賴項，所以我們甚至不需要更改CMakelists.txt或manifest.xml。然而，當我編譯代碼，我還是得到這樣的錯誤：

/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:53: undefined reference to `YAML::Parser::Parser(std::basic_istream<char, std::char_traits<char> >&)' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:54: undefined reference to `YAML::Node::Node()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Node::~Node()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Parser::~Parser()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Node::~Node()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Parser::~Parser()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Node::~Node()' 
/home/aramus/fuerte_workspace/sandbox/image_test/src/image_test.cpp:92: undefined reference to `YAML::Parser::~Parser()' 

我已經添加到的CMakeLists.txt唯一的代碼是：

target_link_libraries(${PROJECT_NAME} yaml-cpp) 
rosbuild_add_executable(image_test src/image_test.cpp) 

我在Linux中使用富爾特。任何解決方案？編輯： 我找到了我的解決方案！我改變了我的CMakeLists.txt來構建可執行文件，然後添加yaml-cpp庫！

rosbuild_add_executable(image_test src/image_test.cpp) 
target_link_libraries(image_test yaml-cpp) 

我的CMakeLists.txt中的這兩行工作正常！

這些是鏈接器錯誤。確保你鏈接到庫以及包含它的頭文件。從你提供的鏈接，它出現在你的CMakeLists.txt文件，你需要：

target_link_libraries(${PROJECT_NAME} yaml-cpp)
