Need help with lua and luasql

Stevie

To make this short, I want to use mongoose web server (the MIT version: https://github.com/civetweb/civetweb ) with lua and with luasql library.

I can compile mongoose and lua easy but I have no clue how to compile luasql with it, I never compiled a lua module, and I do not even know if compiling luasql with lua and mongoose would be compatible. Has anyone done this?

Also most of the articles say "just use lua rocks" which I can't, since lua is compiled with mongoose (so its just one binary file).

Any help would be super appreciated.

It doesn't matter that lua is compiled with mongoose into a single binary.

You can ask Lua to load a shared library or package with require or package.loadlib commands - after setting up the right path. In your case you would need to point it to where your files are available, typically your luarocks distribution.

LuaRocks is just a package manager that puts its files in a nice directory hierarchy. In my case, LuaRocks is installed under /usr/local/lib/luarocks/rocks. For examples on loading libraries take a look at Trepl's Init. It has a custom require function that loads up its requirements. Search for uses of require, package.config and package.loadlib.

You could have a difficult time with Lua if you don't have a fair deal of experience with C.

Looking in the Makefile, could you not compile using WITH_LUA_SHARED=1 instead of WITH_LUA=1? You should then be able to install/compile Lua seperately from Civetweb and luarocks should not be a problem.

Sadly C is my weak point, and of course I knew about lua require but I guess civetweb/mongoose was updated to support lua ether compiled with it or shared (which I did not know till now.)

@r0t3n
I am truly sorry as stated a bit above I have used mongoose/civetweb about a year ago, and loading other modules was not possible at that time so this opens up alot for me :-)

You guys made my day since I did not know I could now use lua as shared, this is great.
