[Swig-user] swig -lua does not produce ANSI C

[Matthew B. <mat...@ea...>]

I am trying to get the LUA bindings under windows to work, but have 
failed miserably.
Just working in the examples\lua\simple directory
I run
swig -lua example.i

from the DOS cmd line.

The file example_wrap.c contains a declaration of a pointer that is not 
at the start of the function which causes the Microsoft compiler to 
complain, in particular

Generating Code...


A segment of the example_wrap.c code...
SWIGRUNTIME void SWIG_Lua_NewPointerObj(lua_State* L,void* 
ptr,swig_type_info *type, int own)
{
    if (!ptr){
        lua_pushnil(L);
        return;
    }
    swig_lua_userdata* 
usr=(swig_lua_userdata*)lua_newuserdata(L,sizeof(swig_lua_userdata));    
// get data
    usr->ptr=ptr;    // set the ptr


The declaration swig_lua_userdata* usr=... is not at the top of the 
function definition causing the failure.  Now it is easy to fix this by 
hand and get the code to compile, however Lua will not read in the .dll 
that is created no matter how I set the paths or even if I use a 
complete pathname to the .dll file inside the loadlib() function.  I'll 
play around with this a bit more, but I'm not sure if the Lua bindings 
are useable in this state on a windows machine, at least with a 
Microsoft compiler or any compiler that is strict ANSI C.  I do not want 
to edit all the _wrap.c functions by hand.
