In essence you don't need to include either header into the other. This fixes the circular includes.
friend class Master_Thread; already forward declares Mater_Thread, so you don't need the Master_Thread.h header.
In Master_Thread.h, you can also forward declare
class ROS_Topic_Thread; before the declaration of the Master_Thread class, since you only use references to ROS_Topic_Thread in the

One way seems to be to extract from script tag though you will need to split the text by horoscope:
I am using this nuget package
It is available for both ios and android in pcl.
I am using it to make videos in my app.
Unfortunately, it has issues on iOS that are inside the project, not inside my code.
I am therefore trying to debug the project, not just implement the nuget library.
It does work fine on Android, so all I want to change is the iOS part.
Unfortunately, I dont know how to insert the same library when it isnt a nuget package but just the solution and also how to then adress it from pcl code. I havent found a solution on google, but probably I dont know how to describe the problem well enought.
How can I debug an open source nuget package?

- Download or clone the src code,
- Go to your project in VS,
- Right click on your solution, choose Add -> Existing project,
- Navigate to MediaPlugin-master\src\Media.Plugin and choose Media.Plugin.csproj file,
- Right click on your iOS project (or whatever project where you use the plugin), choose Add -> Reference,
- Check Media.Plugin and click OK,
- Now you should be able to use the plugin in your project code after adding
using Plugin.Media;(and the code of the plugin will be available to you).

One thing that immediately jumps to my eye is that you have actually put
std_msgs::String::ConstPtr as the topic type but have topics
/velodyne_points which should not be of type
std_msgs::String but instead should have a different data types, point clouds I assume, so something like
sensor_msgs::PointCloud2. Therefore you would have to modify the callbacks to their correct data types, e.g.
What surprises me as well is the message
roswtf gives you:
I'm writing a simple Xamarin Forms mobile app (Android and iOS, but focusing on Android for now) as a school project. I'm using Visual Studio 2019 Community and I have installed the NuGet package sqlite-net-pcl v1.7.335
Everything was moving along when suddenly the application started throwing errors any time database access was attempted, saying "DatabasePath must be specified".
Concerned I might have made an error in my code, I created a blank application and attempted only a simple database connection. The same error occurs. Please see my code below.

MainPage before you assign

I'm not able to link external libraries with the libraries I wrote using CMake. I'm wondering if there's something that is needed to be added to my

src) and what would that need to contain?
