Hi David,

Great, thanks so much. I didn't know that there was this difference in MSVC
2005 (I first even failed by choosing the wrong abstractions such that the
threads required Vista rather than Windows 2000 or better). I'll add the fix
to the trunk as soon as possible and let you know.

Thanks
Christian

Hi Christian,

I quote from msdn "Certain functions that depend on a particular version of
Windows are declared using conditional code. This enables you to use the
compiler to detect whether your application uses functions that are not
supported on its target version(s) of Windows. To compile an application
that uses these functions, you must define the appropriate macros." 

The error we receive without the macro is:

.\gecode/support/thread/windows.hpp(77) : error C3861:
'TryEnterCriticalSection': identifier not found

Old versions of Windows (before NT 4.0) did not support the system call
TryEnterCriticalSection on CriticalSection objects. A default Visual C++
build is compatible with old Windows releases, so it does not provide
TryEnterCriticalSection. Defining _WIN32_WINNT to 0x0400 (or greater) solves
this problem.

Hi David,

Sure! I'll add that! Can you enlighten me what this magic incantation does?

All the best
Christian

Hi,

I noticed that version 3.0.x no longer supports the Microsoft Visual C++
2005 Express Edition and indeed the code does not compile using this
compiler. Although the Microsoft Visual C++ 2008 Express Edition is free it
is no option for me to use this one. 


I also noticed it is pretty easy to get the code compiling, running and
passing al the tests again using the Microsoft Visual C++ 2005 Express
Edition. All one has to do is change in "thread.hh"

#ifdef GECODE_THREADS_WINDOWS
#include <windows.h>
#endif

into

#ifdef GECODE_THREADS_WINDOWS

#ifndef _WIN32_WINNT
#   define _WIN32_WINNT 0x400
#endif

#include <windows.h>
#endif

this works for 32 bits and 64 bits machine. Perhaps this can be added in the
next releases?

thanks,
