hello again,
 
now i tried to compile the helloworld example of the howto from johannes zmölning.
 
i'll explain my  done steps:
 
i use dev-c++ for compiling the code.
 
first i copied the text from the tutorial into a file and named it helloworld.cpp
i included it in a project, the m_pd.h, too.
 
then i pressed compile.
 
after that i got the errormessages :
 
In function `void helloworld_setup()':
invalid conversion from `int' to `t_atomtype'
initializing argument 6 of `_class* class_new(t_symbol*, void*(*)(), void (*)(), size_t, int, t_atomtype, ...)'
[Build Error]  [obj1.o] Error 1
 
than i thougth i'll do a casting and put (t_atomtype) before the last argument.
 
after that the messages were:
 
[Linker error] undefined reference to `post'
  [Linker error] undefined reference to `pd_new'
  [Linker error] undefined reference to `gensym'
  [Linker error] undefined reference to `class_new'
  [Linker error] undefined reference to `class_addbang'
  ld returned 1 exit status
 [Build Error]  [obj.dll] Error 1
 
i don't know what i can do next...
 
what kind of project do i have to choose? dll? console? 
should i do it better in visual c++?
 
as you see, i'm not in the know what i'm doing. sorry for wasting you time...
