Ok, I hacked away a bit, it's not pretty, but I got it to work in MSW.
I downloaded the sources for luasocket-2.0.tar.gz. Compiled it using
MSVC 2005 express using the sln file, I had to edit the *.vcproj to
point to wxLua/module/lua/include for the include path to lua.h.
I edited mime.h/c and added
MIME_API int luaopen_mime(lua_State *L);
MIME_API int luaopen_mime(lua_State *L) {
return luaopen_mime_core(L);
}
edited socket.h/c and added
LUASOCKET_API int luaopen_socket(lua_State *L);
LUASOCKET_API int luaopen_socket(lua_State *L) {
return luaopen_socket_core(L);
}
*** I don't know why I have to do that?
I then created a dir called "socket" and "mime" in the
luasocket-2.0/src dir and copied (not moved) all the lua files into
them. I moved src/mime.dll to src/mime/core.dll and src/socket.dll to
src/socket/core.dll. You HAVE TO either delete src/socket.dll and
src/mime.dll or get rid of them somehow, otherwise require tries to
load them instead of mime.lua and socket.lua and they have to both be
called core.dll.
src/mime.lua -- these two are already there, leave others too
src/socket.lua
src/mime/core.dll
src/socket/core.dll
src/socket/ftp.lua
src/socket/http.lua
src/socket/smtp.lua
src/socket/socket.lua
src/socket/tp.lua
src/socket/url.lua
I edited src/compat/compat5.1r4/compat5.1.lua to have this
package.cpath = os.getenv("LUA_CPATH") or
"./?.dll;" ..
instead of ?.so for unix systems. I could have just used the
environment variables, but after some debugging about why it couldn't
find the libs I just left it the way I had it.
It works! Both using the lua.exe program and wxlua.exe. I ran the
programs from the luasocket-2.0/src dir like this
../../wxLua/bin/wxlua.exe wxlua_socket.lua (the name I gave your program)
(note also I'm using cygwin in Windows so I use forward slashes)
I made some tweaks to wxLua.exe to make it handle the errors a little better.
I'm not sure that this helps at all since I really just trashed
things, but the problem you have is with the paths not being right and
it not being able to find either the lua or dll files for the module's
require.
To help debug things change src/compat/compat5.1r4/compat5.1.lua
At the top add the "print" to this list of functions
local print, assert, error, getfenv, ipairs, loadfile, loadlib, pairs,
setfenv, setmetatable, type = print, assert, error, getfenv, ipairs,
loadfile, loadlib, pairs, setfenv, setmetatable, type
then later on add some "print" statements
local function search (path, name)
...
print("search ", c)
local function loader_C (name)
print("loader_C ", name)
local function loader_Lua (name)
print("loader_Lua ", name)
and whatever else seems necessary to help you understand why it cannot
find what it's looking for.
Good luck,
John Labenski
