Hello,

this is the relevant part of the error message. As usual, you can find it
by searching the first occurrence of a word "error".

This particular message says that the C++ data hiding definitions conflict
at src/objects.h file around line 179. As the compilers develop futher,
this kind of stuff seems to happen ; sorry for the inconvenience...

So please edit the src/objects.h file from around line 179 from this:

class object_location
{
	protected:

	friend obj_loc_data * dummy_object::GetLocDataRW(void) const;

to this:

class object_location
{
	//protected:
	public:

	friend obj_loc_data * dummy_object::GetLocDataRW(void) const;

This will loosen the definitions and the program should compile. If you
get stuck in an identical error message elsewhere, the fix is similar ;
just replace "private" or "protected" with "public".

Regards,
