error: ‘toROSMsg’ is not a member of ‘pcl’

这个错误通常是由于缺少 PCL 的 ROS 包所导致的。请确保你已经安装了 `ros-<distro>-pcl-ros` 包,其中 `<distro>` 是你正在使用的 ROS 版本,例如 `kinetic` 或 `melodic`。如果你已经安装了该包但仍然出现此错误,请确保你的程序中正确地包含了 PCL 和 PCL ROS 的头文件,并且正确地链接了相关的库。

error: ‘ExtractIndices’ is not a member of ‘pcl’
This error message means that the compiler is unable to find the definition of the function or class called "ExtractIndices" within the "pcl" namespace. There could be several reasons for this error, such as:
1. The function or class definition may not be included in the header files or libraries that are being used in the program.
2. The function or class definition may be misspelled or named differently.
3. The function or class definition may be defined in a different namespace.
To resolve this error, you can try the following steps:
1. Check if the function or class definition is included in the header files or libraries that you are using in your program.
2. Check if the function or class name is spelled correctly and matches the definition.
3. Check if the function or class is defined in a different namespace and use the appropriate namespace prefix to access it.
If none of these steps work, you may need to consult the documentation or seek help from the community or support team for the library or framework that you are using.
error: ‘pointToLineDistance’ is not a member of ‘pcl’
这个错误提示意味着编译器无法在 `pcl` 命名空间中找到名为 `pointToLineDistance` 的成员函数。
这可能是因为你没有正确地包含所需的头文件或链接所需的库。请确保在程序中包含了正确的头文件并链接了必要的库。
`pcl::pointToLineDistance` 是 PCL(Point Cloud Library) 中的一个函数,用于计算点到直线的距离。因此,你需要确保你已经正确地安装了 PCL 库,并在程序中包含了正确的头文件。
正确的包含头文件的方式可能如下所示:
```cpp
#include <pcl/common/distances.h>
```
此外,你还需要在链接时链接 PCL 库。在使用 CMake 构建你的项目时,你需要使用 `find_package(PCL REQUIRED)` 来找到 PCL,并将它添加到链接器中,例如:
```cmake
find_package(PCL REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
target_link_libraries(your_project ${PCL_LIBRARIES})
```
如果你使用的是其他构建工具或没有使用 CMake,请查看 PCL 的文档以了解如何正确地链接 PCL 库。
