I'm trying to wrap a class from a library I'm using in Lua. Specifially, I'm trying to wrap the color class from SFML. The full source for the color class can be seen here and here.
This is the function that's that I'm failing in.
int SFColor_new(lua_State* L)
{
// omitting part where I set r, g, b, and a
new (lua_newuserdata(L, sizeof(Color))) Color(r, g, b, a); // Line 47
luaL_getmetatable(L, LuaInfo<Color>::myMetaTableName);
lua_setmetatable(L, -2);
return 1;
}
And this is the error
LuaSFMLColor.cpp: In function ‘int ag::SFColor_new(lua_State*)’:
LuaSFMLColor.cpp:47: error: no matching function for call to ‘operator new(unsigned int, void*)’
<built-in>:0: note: candidates are: void* operator new(unsigned int)
make: *** [game] Error 1
I do similar things in a few other places without running into this error, so I'm not sure what would be causing it. Looking at the Color's source code I don't see anything weird or out of the ordinary, and I've run out of ideas. I've also tried using the default constructor (i.e. no arguments) and then just setting the value afterward, but that didn't do any good either.
