You must include these definitions in the header file. Also you must
remove the #ifndef from your main.cpp.

I mean this:

 #include <cstdlib>
 #ifndef arrh_H
 #include "arrh.h"
 #endif

should become this:

#include <cstdlib>


Also remove the #endif from the main.cpp. The #ifndef #endif should be
placed in the header files only. I mean your header file should become:


 #ifndef arrh_H
 #define arrh_H
 
 [...]
 
 class arrhenius
 {
  public:
  arrhenius();
  [...]
  bool calc();
} arh;

// Member function definitions here


#endif


No other macros in main.cpp. Also better choose longer name in the place
of arrh_H.
