Hi
I'm just starting out with c++ (coming from Python) so bare with me
I'm trying to get the CommandLineRendering part of the SDK to work. In "main.ccp" theres a section under "PluginMessage" with code for command line rendering:

             
case C4DPL_COMMANDLINEARGS:   
     //sample implementation of command line rendering:   
     //void CommandLineRendering(C4DPL_CommandLineArgs* args);   
     //CommandLineRendering((C4DPL_CommandLineArgs* )data);   
     ..........

If i uncomment this like this, add "Bool RegisterCommandLineRendering();" to "main.h" and Build it:

             
case C4DPL_COMMANDLINEARGS:   
     //sample implementation of command line rendering:   
     void CommandLineRendering(C4DPL_CommandLineArgs* args);   
     CommandLineRendering((C4DPL_CommandLineArgs* )data);   
     ..........

I get theese errors:

  
Undefined symbols for architecture x86_64:   
"CommandLineRendering(C4DPL_CommandLineArgs* )", referenced from:   
      PluginMessage(int, void* ) in main.o   
ld: symbol(s) not found for architecture x86_64   
clang: error: linker command failed with exit code 1 (use -v to see invocation)

What am i doing wrong?

Cheers

You've uncommented the line

             
//void CommandLineRendering(C4DPL_CommandLineArgs* args);

and you shouldn't. It's there in the comment to show the prototype of the function to call for the CommandLineRender example in commandlinerender.cpp.

Hm, i must be doing something else wrong because only uncommenting "CommandLineRendering((C4DPL_CommandLineArgs* )data);" in main.ccp gives the same error on compile.

Hi Bonsak,

The code in the SDK for the CommandLineRendering example needs some fixes and has to be changed.
I'll try to explain the changes:

In commandlinerender.cpp remove the "#if 0" macro at the beginning and its respective "#endif" at the end of the file:

 ~~#if 0~~
  
#include "c4d.h"
#include <string.h>
#include <ctype.h>

 ~~#endif~~

In the same file change the definition of CommandLineRendering() function from

static void CommandLineRendering(C4DPL_CommandLineArgs* args)

to

void CommandLineRendering(C4DPL_CommandLineArgs* args)

Add its declaration in main.h :

Bool RegisterCustomDatatypeCustomGUI();
  
void CommandLineRendering(C4DPL_CommandLineArgs* args);
  
#endif // MAIN_H__

And include "main.h" in commandlinerender.cpp:

#include "main.h"
  
Float lastProgressValue = -1.0;
RENDERPROGRESSTYPE lastProgressType = RENDERPROGRESSTYPE_AFTERRENDERING;

The SDK example for CommandLineRendering will be fixed and updated online soon in its GitHub PluginCafe repository.

Thanks a alot! It's pretty intimidating starting out with C++ so your help is very much appreciated.
I'm still getting an error on compile after changing what you suggested:

commandlinerender.cpp:243:22: No viable conversion from 'Char *' (aka 'char *') to 'AutoGeFree<char>'

But i just commented out the whole block from here (commandlinerender.cpp) :

else if (!strcmp(args->argv[i], "-sdk_oformat"))

This compiles fine and is perfectly ok for now.

In "main.h" i think it needs to be something like:

CommandLineRendering((C4DPL_CommandLineArgs* )data);

to actually call the function in "commandline.ccp" not:

void CommandLineRendering(C4DPL_CommandLineArgs* args);

as that is the same as the declaration?

Yes in main.cpp you can remove the line with the function prototype for CommandLineRendering() and just keep the line calling it.

Thanks! It works fine on the command line now. But it crashes cinema when i start c4d in gui mode with commandlinerender plugin in the plugin dir. I'll investigate more.
