I want to add a couple of functions to the LuaInterpreter.dll that suit my needs for a challenge I am creating.

Before adding anything to the source files, I tried to recompile the vanilla ones that come with Orbiter 2010 P1, to see if I have the development environment setup properly.

But I am getting these warnings:

Code:

1>LuaInterpreter - 0 error(s), 4 warning(s)
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

they correspond to these lines of code (which I haven't touched) in the Interpreter.cpp file (bold):

Code: 
COLOUR4 Interpreter::lua_torgba (lua_State *L, int idx)
{
	COLOUR4 col = {0,0,0,0};
	lua_getfield (L, idx, "r");
	[B]if (lua_isnumber(L,-1)) col.r = lua_tonumber (L, -1);[/B]
	lua_pop (L,1);
	lua_getfield (L, idx, "g");
	[B]if (lua_isnumber(L,-1)) col.g = lua_tonumber (L, -1);[/B]
	lua_pop (L,1);
	lua_getfield (L, idx, "b");
	[B]if (lua_isnumber(L,-1)) col.b = lua_tonumber (L, -1);[/B]
	lua_pop (L,1);
	lua_getfield (L, idx, "a");
	[B]if (lua_isnumber(L,-1)) col.a = lua_tonumber (L, -1);[/B]
	lua_pop (L,1);
	return col;
}

When I run a scripted scenario with the recompiled dll (In the D3D9 client), I see no problems during the simulation, but when I exit I get this msg:

At first I thought it was the AscensionUltra creating a problem, but I've also tested it on a clean installation with the same results.

Any ideas on how to fix this? I am mainly interested in the D3D9 client, since my aged PC gets a much better frame-rate.

The warnings are pretty straightforward: Number is of type double, and you are implicitly casting it to float. The compiler is warning you that there is a loss in precision of which you might not be aware.

So, the compiler is merely telling you that it cannot clearly deduct if that was your intent. This won't lead to problems, unless you really do need the double precision and weren't aware that you are casting to float.
If you don't need the precision and it was your full intent to cast to float, you can leave the warnings. Or, if you prefer your code to compile without warning, you can cast explicitly:

Code: 
if (lua_isnumber(L,-1)) col.r = (float) lua_tonumber (L, -1);

In this case the compiler knows that you are fully aware of what you're doing and will not throw a warning.

I don't know where the error on exit comes from, but I'd consider it impossible that it's got anything to do with this.

Did you try to compile the entire Lua subsystem, or just LuaInterpreter? From your logfile I see that LuaInline still has the original build date. This could be a problem, since the dependent modules (LuaInline, LuaMFD and LuaConsole) call routines in LuaInterpreter, so they may have gone out of sync.

It's best to recompile the entire subsystem. Just load the LuaScript solution file and rebuild. LuaInterpreter should already be registered as a dependency for the other modules.

If that doesn't help, you could build debug versions of the Lua modules and try to figure out if you can locate the problem. Since it occurs on exit, a good starting point would be the destructors of the various Lua modules.

Also make sure that your recompiled LuaInterpreter.dll and LuaInline.dll modules actually end up in the Orbiter root directory. I can't remember if the project files do that automatically, or if you have to copy the files by hand. LuaMFD.dll and LuaConsole.dll on the other hand should end up in Modules/Plugin.

Does Lua actually work with your recompiled LuaInterpreter.dll? It's curious that problems should only arise on exit.

Thanks for replying martin.
I recompiled just the interpreter; I'll try recompiling the whole project and see how that works.
Lua works fine with just the recompiled LuaInterpreter.dll. No problems during the simulation, just the problem on exit.

---------- Post added at 22:57 ---------- Previous post was at 22:02 ----------

Before compiling the whole project, I tried just the LuaInline and the LuaInterpreter. The problem on exit is gone. Everything seems to be working properly.
Just to be on the safe side, I'll also recompile the whole project, after I've added a couple of things in the interpreter, that I need for a challenge I am making.

NonsphericalGravityEnabled() and oapiOpenMFD (mode, mfd)

What I want to do, is to check whether the NonsphericalGravity is enabled on scenario start and to be able to turn off the left and right MFDs via the script.

Thanks for the help!
