Re: [Wxlua-users] require problem with luasocket

[Marcos <mar...@ya...>]

Thanks, John

I will try.

But, I think wxlua.exe must correctly use the require function without  
recompile libraries, because my goal is to use the binaries disposed on  
the web. Example is luasql, luazip, luasocket and so..

Another question is: You have a project to build wxLua module(dll,so) for  
dynamic load with lua.exe?

Thanks in advance
