socket = require("socket")

[zmarotrix]

On Windows, socket = require("socket") causes an error saying;

NLua.Exceptions.LuaScriptException: error loading module 'socket.core' from file '.\socket\core.dll':
    dynamic libraries not enabled; check your Lua installation

I've recompiled my Lua interpreter and made sure they are enabled. Does Bizhawk have a built-in Lua interpreter? If so, how can I update it?

[vadosnaprimer]

Try luainterface instead of nlua. Somewhere in advanced config.

[zmarotrix]

I got the same error.

[zmarotrix]

Nevermind, I reloaded the Emulator and now I'm getting this:

NLua.Exceptions.LuaScriptException: error loading module 'socket.core' from file '.\socket\core.dll':
%1 is not a valid Win32 application.

[vadosnaprimer]

You're obviously still using nlua, you need luainterface.

Weird, I have that option checked, restarted the emulator and all. I'm not sure what's going on.

Here are my settings

Yeah this is stupid. It seems to need @zeromus.

You cant just slop random lua plugins into bizhawk. See here for all the annoying complexities:

Sounds like your bug is due to using a 32bit dll, anyway

[udoheld]

I followed the instructions given on SO e.g.

• download http://files.luaforge.net/releases/luasocket/luasocket/luasocket-2.0.2/luasocket-2.0.2-lua-5.1.2-Win32-vc8.zip
• use the following structure

/emuhawk.exe
/Lua (untouched)
/Socket/ftp.lua,http.lua,etc.
/ltn12.lua,socket.lua,mime.lua
/lua5.1.dll
/mytest.lua

I get the following error leaving out the "core.dll" as described:

NLua.Exceptions.LuaScriptException:
[string "main"]:2: module 'socket.core' not found:
no field package.preload['socket.core']
no file '.\socket\core.lua'
no file 'D:\emu\BizHawk-2.2.1\lua\socket\core.lua'
no file 'D:\emu\BizHawk-2.2.1\lua\socket\core\init.lua'
no file 'D:\emu\BizHawk-2.2.1\socket\core.lua'
no file 'D:\emu\BizHawk-2.2.1\socket\core\init.lua'
no file 'd:\Program Files (x86)\Lua\5.1\lua\socket\core.luac'
no file '.\socket\core.dll'
no file 'D:\emu\BizHawk-2.2.1\socket\core.dll'
no file 'D:\emu\BizHawk-2.2.1\loadall.dll'
no file '.\socket.dll'
no file 'D:\emu\BizHawk-2.2.1\socket.dll'
no file 'D:\emu\BizHawk-2.2.1\loadall.dll'

If I do put the "core.dll" from the download above into the socket folder it will complain:

NLua.Exceptions.LuaScriptException: error loading module 'socket.core' from file '.\socket\core.dll':
%1 is not a valid Win32 application.

[zeromus]

You must also change the bizhawk setting to use luainterface instead of nlua

[udoheld]

I changed that already and the config.ini reads (for both of my release and dev versions)

"UseNLua": false,

and when trying the current dev version it seems to pull load "LuaInterface.dll" at "EmuHawk.exe!BizHawk.Client.EmuHawk.Program.CurrentDomain_AssemblyResolve(object sender, System.ResolveEventArgs args) Line 347"
so I'd say it does that. And it should be the same for the released version.

The message is slightly different:

NLua.Exceptions.LuaScriptException:
error loading module 'socket.core' from file '.\socket\core.dll':
The specified module could not be found.

[udoheld]

Ok. I noticed for dev the file structure has to be put into the "output" directory, but it now prints

NLua.Exceptions.LuaScriptException: error loading module 'socket.core' from file '.\socket\core.dll':
%1 is not a valid Win32 application.

as well.

[zeromus]

ok, NOW the instructions on stackoverflow works.
Looks like even when you use luainterface all the errors and stuff say nlua, because lame reasons

[udoheld]

Thx, it works for me now. @zmarotrix you may want to retry the daily build.
