2.1. gcc is complaining about the following code:
#ifdef LUA_DEBUG
if(0 != lua_gettop(L))
goto HandleErr;
#endif
...
const DoubleRect& pos = curSprite->getPos();
...
#ifdef LUA_DEBUG
HandleErr:
lua_stringerror(L, "GetPosition expects 0 arguments");
return 0;
#endif
The error messages (there are three) are:
LuaSpriteInterface.cpp:1205: error: jump to label 'HandleErr'
LuaSpriteInterface.cpp:1186: error: from here
LuaSpriteInterface.cpp:1194: error: crosses initialization of
'const DoubleRect& pos'
Am I doing something non-standard here? How can I fix it? I would
like to continue using goto: as this problem occurs in many places
in my code.
I'm not sure what the C++ standard says about this, but GCC is
definitely pickier than CodeWarrior about such things. CodeWarrior
seems to only complain when something other than a simple built-in
type is being instantiated.
A simple fix is to enclose the block that uses 'pos' between { }.
