Sorry, somehow forgot about this. TBH, if this doesn't really fix the UBSAN problems (as the game lib still can't be built) I don't really see the point of this change. Implementing static linking of the game lib seems like the way to go, and shouldn't be too hard (see d3wasm) - though in case of dhewm3 it of course needs to be optional (enabled by a CMake option that's off by default - ideally we could switch between "off" / "statically link base" / " statically link d3xp"). |

Well there's also the FIXME comment (that I seem to have forgotten to remove) that says this should be done. @HarrievG do you want to incorporate this into your changes? |
Please don't - this breaks the Game API (=> makes mod DLLs incompatible), without solving any problem (that old FIXME isn't worth it) If we break the game API in the future for some other reason we could think about incorporating this change |

I was under the impression that he needed to change this class anyway. |

As far as I see #339 doesn't touch Game.h |

I'll check it out later this night or this week, will rebase, and make it
ready.

Well, we are waiting :D |

Rebased and removed the fixed FIXME comment. |

There was a problem hiding this comment.

Virtual functions bind dynamically, but default function parameter values bind statically.
So if you implement this function in a derived class with a different default parameter, and you call it through a base pointer without parameter, it will use the default parameter specified in the base class, not the one in the derived class!

Split
idGameEditinto base classidGameEditBasewhich is in the main binary andidGameEditwhich is only referenced in the game libraries.This was an attempt to fix UBSAN compilation. The main binary now compiles with UBSAN but the game library does not. It requires vtables of things which only exist in the main binary. I think the way to make it work will be to implement static linking of game library. So this might not even be necessary. Thoughts?
