| Would it be possible to have Luacom, luasocket, et al. in a separate directory than the lua directory, and Mushclient set package.cpath to be %LUA_CPATH%;<MCInstallDir>\Lua\clibs?
I already have Lua for Windows installed, and have most if not all of these dlls. I don't want to run into DLL hell because versioning issues.

| Well I don't really want to fiddle with the Lua package.cpath if I can help it, because there could be other side-effects.
Where do you have yours installed? Will they necessarily clash?
In any case, you can set the package.cpath in your Lua sandbox, which is a once-off change to affect all your scripts. |

| In any case I think we are already in DLL hell, frankly.
For one thing, some of the Lua libraries load against lua5.1.dll and others against lua51.dll. They have worked around that a bit, I believe, by releasing a "stub" DLL that redirects from one to the other (I forget which the "real" one is).
I found a while back that downloading some of the LuaBinaries files and trying to run them is indeed a special form of hell.
That is one of the reasons I am distributing my own copies, which are basically compiled from the original source, but at least linked against the "right" libraries to run with MUSHclient (eg. not against Cygwin).

| I have LfW (Lua for Windows) installed to C:\Lua\5.1 . I manually set a system environment variable LUA_CPATH to C:\Lua\5.1\clibs\?.dll;

| | I would have to agree with Nick here, the sandbox code is almost certainly the best place to set the cpath. |

lua5.1.dll is the real one.
lua51.dll is the stub (since we're not at version 51 yet) | | Top |

| Funny you should say that. I raised this issue in 2008 on the Lua mailing list and got told:
Mike Pall said:
The standard DLL name "lua51.dll" has been selected more than three years ago. Around twice every year someone comes along and thinks "Oh, we absolutely need a dot in the DLL version number".
and:
Thomas Lauer said:
As Mike wrote, the "standard naming convention", insofar as there is one, is to have the version number w/o dots or other embellishments.
Rightly or wrongly (personally I like the dot, since, as you say, it isn't Lua version 51), the issue hasn't really been resolved, and indeed people are prepared to argue both sides of the case.
