LuaSocket in Windows - How to install and use it in an Eclipse Project - eclipse

Question

When I run my code in terminal,
local function main()
local socket = require ("socket.http")
end
main()
I get this error/message: module 'socket.http' not found:
no field package.preload['socket.http']
no file '/usr/local/share/lua/5.2/socket/http.lua'
no file '/usr/local/share/lua/5.2/socket/http/init.lua'
no file '/usr/local/lib/lua/5.2/socket/http.lua'
no file '/usr/local/lib/lua/5.2/socket/http/init.lua'
no file './socket/http.lua'
no file '/usr/local/lib/lua/5.2/socket/http.so'
no file '/usr/local/lib/lua/5.2/loadall.so'
no file './socket/http.so'
no file '/usr/local/lib/lua/5.2/socket.so'
no file '/usr/local/lib/lua/5.2/loadall.so'
no file './socket.so'
I'm working with lua in Windows and I have no idea of how to implement this.
I want to use LuaSocket to get an image from http repository and then get its base64 encoded, without downloading the image. This with an image in a filesystem, this solution works:
dofile("C:\\Users\\se47596\\Desktop\\LUA\\prueba2\\src\\Base64.lua")
imagen = "C:\\Users\\se47596\\Desktop\\LUA\\prueba2\\src\\pruebaAsyncOCR.png"
local function main()
imfh = io.open(imagen,'rb')
imblob = imfh:read('*a')
imfh:close()
print("ImageData="..enc(imblob))
end
main()
What files should I import to my Eclipse project? I saw these operations but I don't know how to use them...
--package.path = "./lua/modules/?.lua"
--package.cpath = "./lua/modules/?.dll"
--local socket = require ("socket")
how should I structure my project? At least I have this:
MyProjectFolder
|__src
|__Base64.lua
|__main.lua
Could you help me please? I want to prove it out of the Lua interpreter. I saw also these solutions, but I couldn't make it work in my Eclipse project, maybe I need a previous step.
Do I need to create a library? How could I do this in that case?

Answer 1

First error looks like you are running in Linux??
Have you successfully installed LuaSockets? Its written in C so you need a compiler to install it. That can be found in Microsoft developer tools. You can also use cygwin.
Alternatively if you have mingw installed you can first download:
https://github.com/pkulchenko/ZeroBraneStudio/blob/master/build/build-win32.sh
Then you can run:
bash ./build-win32.sh lua luasocket

Answer 2

I can build them by the way blow :
(1) replace gcc/g++ in build-win32.sh like thie:
GCC=x86_64-w64-mingw32-gcc
GPP=x86_64-w64-mingw32-g++
#gcc $BUILD_FLAGS
$GCC $BUILD_FLAGS
(2) apt-cyg cmake unzip mingw64-x86_64-gcc-g++
(3) bash ./build-win32.sh lua luasocket
