[gecode-users] Which version of MSVC on Windows?

[Christian Schulte]

Actually, when I tried to compile Gecode with MSVC 2005 there were way more
errors than that (even central parts of the kernel would have to be
rewritten in order to compile as there seems to be a quirk with friend
declarations).

So the difference is between _compiling_ and _using_ Gecode with MSVC 2005. 

If you send me a patch I could add that to the trunk of Gecode but I would
still not say that 2005 is supported (actually, we just added a check in
Gecode's configure script that makes it barf if it does not find MSVC 2008
or better).

Cheers
Christian

Well actually i still need to stick with MSVC 2005, so I modified the code
to
compile with MSVC 2005, it's not that much work, only had to help the
compiler
in deciding what type to use:

so what I did was to modify the files at the coresponding line

gecode\gist\gist.hpp(163)
gecode\gist\gist.hpp(167)
gecode\gist\gist.hpp(171)
gecode\gist\gist.hpp(175)
gecode\driver\options.hpp(362)
gecode\driver\options.hpp(366)
gecode\driver\options.hpp(370)
gecode\driver\options.hpp(374)

and do a static cast to int for the parameter of the 
call: someobject[mustcast]

like this example:
from:  _click[n_click++]
to:    _click[static_cast<int>(n_click++)]

I imagine that there is no use in doing this for the new releases yourself,
but
if you want I can provide the modified source code to work with MSVC 2005 or
even the already compiled binary files (I compiled it only without gist
because
of configuration problems with qt, but this should be fixed soon)
