lua failing to load modules

[Gordo]

I'm attempting to make lua file system work with Avorion's lua. Now, by default require("module") can load lua modules.

 

Using the following lua:

local lfs = require("lfs")

 

I compiled lua file system using Mingw-w64 4.9.2 using the following commands:

gcc -c -Wall -fpic lfs.c -IC:/lua/include

gcc -shared -o lfs.dll lfs.o -LC:/lua/ -llua52

 

Which produced the lfs.dll file. Which is usable in normal lua52 and I've tested that, it loads fine.

 

I double checked what version of lua you're using in your engine and it reported lua52.

 

So then I did a simple test and used require("lfs") the module is found and the server crashes.

 

it then spits out this error

So then I changed the load library code in the DLL and commented out the default library functionality to make sure the DLL was loading, and it was, the engine stopped crashing.

LFS_EXPORT int luaopen_lfs (lua_State *L) {
        //dir_create_meta (L);
        /*lock_create_meta (L);*/
        //luaL_newlib (L, fslib);
        //lua_pushvalue(L, -1);
        //lua_setglobal(L, LFS_LIBNAME);
        //set_info (L);
        return 1;
}

 

Then i tested a basic example from the lua c api wiki and the same crash happened.

 

static int l_sin (lua_State *L) {
        double d = luaL_checknumber(L, 1);
        lua_pushnumber(L, sin(d));
        return 1;  /* number of results */
}

LFS_EXPORT int luaopen_lfs (lua_State *L) {
        lua_pushcfunction(L, l_sin);
        lua_setglobal(L, "mysin");
        //dir_create_meta (L);
        /*lock_create_meta (L);*/
        //luaL_newlib (L, fslib);
        //lua_pushvalue(L, -1);
        //lua_setglobal(L, LFS_LIBNAME);
        //set_info (L);
        return 1;
}

 

Can you please fix this as it's not fun being unable to use these modules?

 

LuaFileSystem is not really the main one I wanted to test but it was the smallest. (it's a 2 file library)

This would be great, as there are many lua modules that modders can take advantage of.

Any updates on this, I would appreciate any feedback
