luarocks install lfs

[GoogleCodeExporter]

What steps will reproduce the problem?
1.luarocks install lfs
2.or luarocks --local install lfs

What is the expected output? What do you see instead?
i see error lfs already exists. 

What version of the product are you using? On what operating system?
LuaForWindows_v5.1.4-46, ms windows xp sp3, i386.

Please provide any additional information below.
luarock can't update lfs because luarocks use lfs. I think that better way move 
luarocks in dependent dir with personal lua, lfs and etc. binaries.

Is there any way to update luafilesystems?

I think it would be easiest to just remove C:\Programming\Lua\5.1\clibs/lfs.dll first before installing with LuaRocks.

[Rainrider]

I tried that already. One can't run luarocks without lfs.dll. This is what the original issue author meant by luarocks depending on luafilesystem I think

[Rainrider]

This is the error message when trying to install luafilesystem with clibs/lfs.dll removed

This feels like a LuaRocks issue. I have no experiance with that on Windows. I would ask the LuaRocks mailing list. https://lists.sourceforge.net/lists/listinfo/luarocks-developers

Sorry.

[rjpcomputing]

Are you running this from a Visual C++ command prompt? Or a minGW command prompt? That might be needed.

[Rainrider]

Sorry for the late response. Visual C++ command prompt. It's the Enterprise 2015 edition if that matters.

OK so I worked up a solution to update LuaRocks to a MUCH newer version. I am going to add the file to the download section of GitHub Steps:

1. Install LuaForWindows
2. In a temp location, unzip http://keplerproject.github.io/luarocks/releases/luarocks-2.2.2-win32.zip
3. In same location, unzip the downloaded lfw_luarocks-2.2.2-win32.zip from GitHub project
4. In same location, open a command prompt

• if you want to install rocks, make it a "Visual Studio Command Prompt"
• make sure LUA_DEV environment var set correctly
• will probably need to open command prompt as Administrator
• admin rights are typically need to write to "Program Files" 5) Run lfw_install.bat
• this "manually" installs 2.2.2 in the LfW directory 6) Optionally run lfw_update_rocks.bat
• this will try to install (get, compile, deploy) rocks for a lot of modules
• A LOT of these will fail
• it uses the "popular" list from https://luarocks.org/
• A FEW of these will fail
• in the end you should have 40-50 modules installed as "rocks"
• it does some cleanup of old stuff if new installed

Here is the link to the file. https://github.com/rjpcomputing/luaforwindows/releases/download/luarocks-update/lfw_luarocks-2.2.2-win32.7z

I moved to using https://github.com/Tieske/luawinmulti for the time being. It's minimal and I have full control of what gets installed. It also supports Lua 5.2 and 5.3.

I do appreciate your effort and will keep an eye on your project. Thank you very much
