Could not connect to localhost:8172

[alfredopalhares]

Hello,

Archlinux updated. Lua 5.2 Luasocket from https://github.com/diegonehab/luasocket/tree/unstable Latest Mobdebug from master.

When I run the server.lua and run start.lua i get Could not connect to localhost:8172

[pkulchenko]

@masterkorp, can you run the same scripts using Lua 5.1 and a stable version of sockets? If it works, the issue is likely to be with the new code in mobdebug that uses connect4 method from the unstable branch.

[alfredopalhares]

What stable version of sockets do you recomend ? I am failing to build http://files.luaforge.net/releases/luasocket/luasocket/luasocket-2.0.2

[pkulchenko]

@masterkorp, are you building this luasocket with Lua 5.2? This is probably not going to work as for 5.2 you need the branch you used earlier, but 2.0.2 needs to be compiled with Lua 5.1.

I am using lua5.1 Maybe luasockets its not recognizing it ? pacman -Ql lua51

In file included from luasocket.c:31:0: auxiliar.h:38:61: error: unknown type name ‘luaL_reg’

@masterkorp, this looks like it may still be using Lua 5.2 includes. From auxiliar.h:

#include "lauxlib.h"

int auxiliar_open(lua_State *L);
void auxiliar_newclass(lua_State *L, const char *classname, luaL_reg *func);

Lua 5.1 lauxlib.h includes defined for luaL_reg (line 170):

#define luaL_reg    luaL_Reg

but Lua 5.2 lauxlib.h doesn't include that, which would explain why the type is unknown.

[alfredopalhares]

Sorry for the delayed awsner, I can now confirm luasocket 2.0.2 compiled against working! But I need 5.2 support for my app. If you could port that, or give me pointers how to do it, I would be thankful.

[pkulchenko]

@masterkorp, is this still an issue? Closing for now; please re-open if you have additional information that can help with this.
