Question

我正在尝试使用yaml-cpp并根据wiki，这是一个系统依赖，所以我们甚至不需要更改CMakelists.txt或manifest.xml。但是，当我编译代码时，我仍然会遇到如下错误：

/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()'

我添加到CMakeLists.txt的唯一代码是：

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

我在Linux中使用fuerte。任何解决方案吗？

编辑：我找到了解决方案！我改变了我的CMakeLists.txt来构建可执行文件然后添加yaml-cpp库！

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

我的CMakeLists.txt中的那两行正常工作！

这些是链接器错误。确保您链接到库以及包含其标题。在您提供的链接中，您需要在CMakeLists.txt文件中显示：

target_link_libraries(${PROJECT_NAME} yaml-cpp)

错误在ROS中使用yaml-cpp？
