[gecode-users] Compilation trouble in 64 bit environment?

[Christian Schulte]

Well, as you do not tell which version of Visual Studio you use...

 But there are no issues: Gecode compiles and runs just fine with MSVC 2008
and 2010 both for x86 (32 bit) and x64 (64 bit). The MSVC 2010 compilers
seem to use more memory and seem to take more time, but that's fine. The
warnings you get can be safely ignored (we also test for warnings), somehow
you switched on the highest warning level where everything gets you a
warning (try the standard C++ header files to see what I mean).

I myself use Windows 7 and all the different versions of MSVC mentioned
above, so I can't real see any issues.

Best
Christian

Subject: [gecode-users] Compilation trouble in 64 bit environment?

Hi All,

I have recently upgraded my computer to 64 bit Windows 7 and new visual
Studio installation. After this I get a bunch of warnings like the following
and the compilation takes a long time. Worse, while running the same
problem, the new environment consumes a ton of memory. Did anybody
experience similar issues? Any feedback is appreciated.

Thanks,

Ashis
