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

[Maity, Ashis K]

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
