Struggling with a new lua project

I managed to resolve all my other errors but this set confounds me:

Code:

---

These need to be placed after the .o files compiled as part of your project.

Same result (unless I misunderstood):

Code:

---

mingw32-make POE_BIT=64 -f makefile.mak

Yes, you mis-understood.

After your .o files.

Thaaat's better, still came out with a wierd error however:

Code:

---

mingw32-make POE_BIT=64 -f makefile.mak (in directory: O:\Data\C_Playground\idlejp)

Despite me having this in main.c:

Code:

---

# if defined( _UNICODE ) || defined( UNICODE )
#                define POE_UNICODE
#        endif
#        ifdef POE_UNICODE
int CALLBACK wWinMain(
        HINSTANCE hThis,
        HINSTANCE hPrev,
        LPWSTR lpCmdLine,
        int iCmdShow )
#        else
int CALLBACK WinMain(
        HINSTANCE hThis,
        HINSTANCE hPrev,
        LPSTR lpCmdLine,
        int iCmdShow )
#        endif

---

Any ideas as to why it is expecting the wrong function?

Didn't manage to fix root cause but the app compiled fine once I used both wWinMain & WinMain, my next problem lies with running my lua file, loads fine but doesn't run, just in case can you see anything wrong at all?

Code:

---

lua_State *L = luaL_newstate();
  luaL_openlibs(L);
  iuplua_open(L);
  if(luaL_loadfile(L,"main.lua"))
                bail(L,"Failed to load main.lua");
  if(lua_pcall( L, 0, 0, 0 ))
                bail(L,"Failed to run main.lua");
  lua_close(L);

While you're looking I'll investigate a different suspicion I have related to an apparent MS oversight in CommandLineToArgvW, I made a function to wrapup the exe part and add "0 " before it before calling the function but haven't got round to filtering that "0 " back out after calling it.

Edit: Nope had nothing to do with it
Edit 2: Finally got my compiler to stop complaining of missing lua_tostring so I could diagnose the error and found I had forggoten to actually create a lua file that main.lua was expecting, so went and did that with a basic parameter to build my GUI with (IUP is helpful in that regard) and lua started complaing of invalid characters or something to that effect, here's what my other file consists of for now:

Code:

---

local list = {
        "時々" = {}
}

---

Any ideas of how to handle UTF16 characters?

Post is getting a bit big so here's new one, I managed to get lua to except the name, I've used UTF8 encoding with my file looking like this for now:

Code:

---

local list = {}
list["時々"] = {}

---

Got a different error now related to IUP so I will have to go it alone for now or contact the developer.
