Hi Jeremy,
Ok, I've uploaded the changes and asked the user to test. Will revert with success or failure soon :)

Hi Justin,

Ah, I see the problem. Try the (experimental) MUSCLE archive at the link below and see if it works better for you.... I've replaced the calls to muscleSwapBytes() with inline C code instead. If it works out, I'll keep the
change in the next muscle release (v3.25).

Hi Jeremy,

I updated my MuscleSupport.h file and still no luck with 64bit
platforms, but made some further progress in debugging it:

The client is a C client, hence I'm using MiniMessage, and not the C
class for this.

As its a C client, we are not compiling with the C++, hence the
MuscleSwapBytes function isn't compiled (its surrounded by #ifdef
__cplusplus), but as these targets are intel platforms, I'm assuming
that we can use the MuscleX86Swap* functions instead.

So, I tried to update the #defines to catch if __X86_64__ was defined
and set MUSCLE_USE_X86_INLINE_ASSEMBLY but this hasn't worked.

Anyway, I've tracked back the use of MuscleSwapBytes and its used in
MakePrettyTypeCodeString which is only used for debugging, so I can
get around this for my particular problem, but it would be good to
solve this for 64Bit intels.

I'm not sure where to go from here though, so any adivse is
appreciated. (you can see my changes to MuscleSupport.h at http://

In this case, the released code uses Muscle 3.01 for the clients, but
the server is Muscle 3.21 I've since updated my development copy of
the client to the latest Muscle, but the only changes were in

Hi Justin,

Like you, I don't have any 64-bit systems handy to test on, but
from looking
at the HISTORY.TXT file in the latest MUSCLE release (v3.24), I see

v3.22 Released 7/5/2006
  * Added Lior Okman and Rony Gutherz' patches to re-enable
    on 64-bit systems, Solaris, MSVC, and Windows 2000.

v3.11 Released 3/1/2006
  * Merged in Lior Okman's AMD-64 compatibility patch.

So hopefully everything is 64-bit compatible... perhaps Lior or
Rony could
describe their experiences with muscle in a 64-bit environment.

In any case, I recommend upgrading to the latest version if you
can... just be
sure to read the HISTORY.txt to see what the changes have been
since your
existing version, since some of them may require corresponding
changes to
your program's source code.

What version of MUSCLE are you currently using, btw?

What about 64bit intel boxes? I got reports that it wont compile


Again, I'm using a older version here, so let me know if its fixed or

Hi Justin,

AFAIK Muscle has compiled correctly on Intel-based Macs since the
release, but I merged in your patch anyway since it makes the code
logical (now that __APPLE__ no longer implies PowerPC)

Not sure if this is in the latest code or not, but Muscle wont
compile in intel based mac's due to a macro. Below patch fixes

I also believe that this will have problems on 64bit X86
platforms as
well, but I don't have a box to test on, so no patch :(
