Question

我正在遵循ROS-tutorial，并且在创建自己的包后面临以下行为：如果尝试执行任何已安装的软件包（例如any_package），则会出现以下错误：

[rosrun] Couldn't find executable named <any_package> below /opt/ros/kinetic/share/<any_package>
[rosrun] Found the following, but they're either not files
[rosrun] or not executable:
[rosrun]   /opt/ros/kinetic/share/<any_package>

有帮助吗？

编辑： 如果我执行catkin_find --without-underlays --libexec --share <any_package>，它将得到以下输出：

Multiple packages found with the same name "my_package":
- my_new_package/my_package
- my_new_package/my_package_2

Answer 1

我假设您的工作区受到污染。我假设您只是将my_package复制到my_package_2，而没有编辑package.xml中的my_package_2文件。 tutorial中并没有真正提到它，因为它假定您使用正确的命令来创建带有唯一包名称的清单文件。只需按如下所示编辑名称标签：

<name>my_package</name>

到

<name>my_package_2</name>

在相应的文件夹中。

Answer 2

You have to make sure you edit CmakeLists.txt according to your compile version, c++ executable declaration & Specify libraries to link a library

Below are step step modification and then run catkin_make before running your project:

step 1
add_compile_options(-std=c++11)

step 2
## Declare a C++ executable
## With catkin_make all packages are built within a single CMake context
## The recommended prefix ensures that target names across packages don't collide
add_executable(${PROJECT_NAME}_node src/myproject_node.cpp)

step 3

## Specify libraries to link a library or executable target against
target_link_libraries(${PROJECT_NAME}_node
   ${catkin_LIBRARIES}
 )
