rev 4649 doesn't build on linux

[killerbot]

due to squirrel update ?

inline SQHash HashObj(const SQObjectPtr &key)
{
   switch(type(key)) {
      case OT_STRING:      return _string(key)->_hash;
      case OT_FLOAT:      return (SQHash)((SQInteger)_float(key));
      case OT_BOOL: case OT_INTEGER:   return (SQHash)((SQInteger)_integer(key));
      default:         return hashptr(key._unVal.pRefCounted);  ///<--------------------------------------------
   }
}

../../../../src/include/scripting/squirrel/sqtable.h: In function 'SQHash HashObj(const SQObjectPtr&)':
../../../../src/include/scripting/squirrel/sqtable.h:21: error: cast from 'SQRefCounted*' to 'SQInteger' loses precision

I just compiled it on linux without problems.

For me, too. What compiler are you using?

Edit: I just checked: sqtable.{h/cpp} was not touched at all during the update...?!

Sounds like a 64-bit portability issue. Killerbot: are you compiling for 64-bit?

Hello, I have the same problem on a x86_64 too and my version of gcc is 4.1.2

[killerbot]

just did a build on my laptop --> OK

but the laptop is 32 bit, since it seems a pointer to int or the other way around is happening, I think it's a 64 bit issue, because the machine giving problems is a 64 bit one.

Note : before the update squirrel code builded fine on my 64 bit machine

This part I don't get. Cause really: That part you are mentioning was not modified at all. So how can that be...?! :shock:

[bludo]

That is the question because it was the same for me !

Could really be. SQ(Plus) is not yet 64bit compatible. There are tons of notes within the code accordingly. ;-)
BTW: killerbot: What happens if you use the -m32 compiler switch?

[killerbot]

I think Squirrel was 64 bit compatible, if I remember correctly that was one of the main reasons Yiannis changed to this scripting engine ??

[MortenMacFly]

I think Squirrel was 64 bit compatible, [...]

Squirrel is indeed, but not SQPlus (search for "<TODO> 64-bit" in the code...)...

[killerbot]

maybe one of the types that get translated into one another has changed and those type definitions can be in another file ?

Ok... this should be SQInteger then... let me check...
But anyways: We cannot rely on 64bit compatibility anyway.

Dammed! Maybe I found the error. Could you do me a favour and add the following code into include\scripting\include\squirrel.h:

Code Select Expand


#ifdef _LP64
    #define _SQ64
#endif

Just after:

Code Select Expand


#ifndef SQUIRREL_API
#define SQUIRREL_API extern
#endif

If that's the cause than it's all my fault!!! :roll: :roll: :roll:

I have found the solution looking on squirrel forum (one of the threads : http://squirrel-lang.org/forums/thread/746.aspx) . Compiling squirrel on 64 bits platforms requires to define the _SQ64 variable so I have added in squirrel Makefile the flag -D_SQ64 in CXXFLAGS and then the compilation succeed. Is it possible that something have changed in the configuration script or squirrel code source ? Can somebody fix this problem in codeblocks code source ?

Thanks
