Getting Log: ObjectFactorySystem::AddConstructors() called with no constructors about runtimecompiledcplusplus

This isn't the intended way of using RCC++, which is designed for changing your own code at runtime. It is possible, but it's an advanced use case.

You need to use m_pRuntimeObjectSystem->AddToRuntimeFileList( filename, projectId );.

I think you will also need to set off the first compile after adding a file. I would use a different projectId (default is 0) to your main code so you can recompile only that code if needed and set options for that project separately.

Since the file doesn't exist to start with, RCC++ won't have a pre-compiled set of information about the libraries, includes etc. which this file uses. If the user writes their code by first adding the correct library and includes as per RCC++ before writing any code this should work, but you may want to make sure they always include a header which has the correct includes in it to work well.

One issue for using RCC++ this way is that the scripting system will always need to recompile the source code every run, though it you do not delete the temporary files this should be fairly fast.

I am considering adding improved support for scripting with RCC++ at some point, but currently do not have the time.

Thanks for the suggestion. I'll try to implement that.
But before I do that, the problem at hand right now is the program is not able to find RCCppMainloop.cpp as given in step 3 of the tutorial. It keeps on returning ObjectFactorySystem::AddConstructors() called with no constructors in the console along with Found Directory Maps. I have the file, RCCppMainloop.cpp, in the directory.
RCCppInit()

bool dag::EditorUILayer::RCCppInit()
{
    g_SystemTable.pRuntimeObjectSystem = new RuntimeObjectSystem;
    g_SystemTable.pLogger = &g_Logger;
    if (!g_SystemTable.pRuntimeObjectSystem->Initialise(&g_Logger, &g_SystemTable))
    {
        delete g_SystemTable.pRuntimeObjectSystem;
        g_SystemTable.pRuntimeObjectSystem = NULL;
        return false;
    }

     g_SystemTable.pRuntimeObjectSystem->CleanObjectFiles();
#ifndef _WIN32
    g_SystemTable.pRuntimeObjectSystem->SetAdditionalCompileOptions("-std=c++11");
#endif

    return true;
}

I have the program compiling and running. What might be causing this?

Have you first tried compiling the full example:
https://github.com/juliettef/RCCpp-DearImGui-GLFW-example

If this works then check for differences in logic or build (cmake) settings.

My initial thought is that you don't have RCCppMainloop.cpp in your CMakeLists.txt as per:
https://github.com/juliettef/RCCpp-DearImGui-GLFW-example/blob/main/CMakeLists.txt#L51-L52
