@Riccardo

Thank you very much for your reply Riccardo!
Yes of course you are right - modifying the c4d sdk is a bad way.

I just did this to see what happens.
I will take a close look to the manual you have mentionend and will review
the memory handling in my code.

Hello Cinema Coders,

I am running into a crash when compiling and executing my plugins in Release Mode (Cinema4D R19)
C4D crashes with an application error and a bug report is being generated:

If I compile this plugin in Debug Mode no problem occurs.

As a dirty try-out I modified 2 functions in the cinema.framework:

In file c4d_memory.cpp:

void _GeFree(void** Daten)
{
	if (*Daten)
	
   try 
   {
         {
            C4DOS.Ge->Free(*Daten);
         }

         *Daten = nullptr;
   }

  catch (...)
   { 
   }
}

In file c4d_basplugin.cpp:

void BaseData::Destructor(void)
{
   BaseData* _this;

   _this = this;
  
  try 
   {
      DeleteObj(_this);
   }

   catch (...)
   {
     
   }
}

With the try and catch blocks in these two functions c4D works without crash in Relase mode.

Has maybe someone an idea where to look further regarding this issue?

Thanks a lot for your time!

Hi Riccardo,

please excuse me me for interrupting your work.

I am completely new to the sdk development for Cinamea 4D.
In my company we use currently R 19 to develop plugins in C++
My task is to port our R 19 plugins to R 20.
As far as I could figure out there is a major change in the sdk with the introduction of R 20.

The R 20 cinema.framework compiles ok after running the project tool over it.

But now I have the same problem like viktor had: MAXON_MODULE_ID : undeclared identifier.
In a former post you mentioned to put this ID in the projectdefinition.txt file.
Do I have to create this file manually in all plugins folders?
Do I have to run the project tool over these folders once the projectdefinition.txt file is there?

As far as I have understood the project tool creates the project files for Visual Studio.
But in our R 19 plugin folders these files are already existing. Would it be enough to put an additional
projectdefinition.txt into these folders?

Thank you very much for your time!

Best regards
Andi
