Hi,

Please take the time to read and understand
http://loop.luaforge.net/release/preload.html.

Generate a .c/.h file for each .lua file in the list

     ftp.lua
     http.lua
     smtp.lua
     tp.lua
     ltn12.lua
     mime.lua
     socket.lua
     url.lua

You should now have one C function that is equivalent to each of these
Lua modules. Make sure they have the following names:

     ltn12.lua -> luaopen_ltn12
     mime.lua -> luaopen_mime
     socket.lua -> luaopen_socket
     url.lua -> luaopen_socket_url
     ftp.lua -> luaopen_socket_ftp
     http.lua -> luaopen_socket_http
     smtp.lua -> luaopen_socket_smtp
     tp.lua -> luaopen_socket_tp

Include the .h files and create the following table in your
lua.c:

     static luaL_Reg pre = {
         {"socket.core", luaopen_socket_core},
         {"mime.core", luaopen_mime_core},
         {"socket", luaopen_socket},
         {"socket.smtp", luaopen_socket_smtp},
         {"socket.http", luaopen_socket_http},
         {"socket.ftp", luaopen_socket_ftp},
         {"socket.tp", luaopen_socket_tp},
         {"socket.url", luaopen_socket_url},
         {"mime", luaopen_mime},
         {"ltn12", luaopen_mime}
         {NULL, NULL}
     };

Call this function right after the call to luaL_openlibs in
lua.c:

     void initpre(lua_State *L) {
         const luaL_Reg *lib = pre;
         luaL_findtable(L, LUA_GLOBALSINDEX, "package.preload",
             sizeof(pre)/sizeof(pre[0])-1);
         for (; pre->func; pre++) {
             lua_pushstring(L, pre->name);
             lua_pushcfunction(L, pre->func);
             lua_rawset(L, -3);
         }
         lua_pop(L, 1);
     }

Compile everything together in a big mush. Voila.

Regards,
Diego

Disclamer: It's late and I didn't test this code, but the idea should
work.
