Question

While combining boost, a demo project and another library I ran into problems with my definitions.

Having one X.cpp file, including a class X, I need to use this class for a variable in a Y.cpp, to convert a void pointer as a pointer to this class.

In Code:

X.cpp

#include <boost/...>

class x {
}

Main(){
  x c(...);
  handler = init(&c);
  anotherLib-Function(void *handler); 
  //will call function in Y.cpp with c as void pointer
}

Y.cpp

#include ?!!

yfunction(void *c){
  x *cHandle;
  *cHandle = (x *)c;
  (*cHandle).write("texte");
}

This is how it worked last time – kind of. I would very much appreciate a solid solution for this messy contruct or anything making this code better/working. Thanks!

Answer 1

Split the X file in a header file (X.h) containing class declaration and a source file (X.cpp) containing definitions for the class constructors, methods etc.
Now include the header file in the Y.cpp file of yours. Then compile somehow like this:

g++ Y.cpp X.cpp
